Pear Diamond Necklace Australia: A Guide to the Pear Cut Solitaire
The pear cut is one of the oldest diamond shapes still in widespread use. It combines two cutting styles — the rounded base of the brilliant cut and the tapered point of the marquise into a silhouette that is immediately recognisable and distinctly elongating when worn as a necklace.
This guide covers the properties of the pear cut, what to look for when choosing one, and how the Bellari pear diamond solitaire necklace is made.
What Makes the Pear Cut Distinctive
The pear cut has 58 facets arranged in a pattern derived from the round brilliant. The rounded base refracts light similarly to a round cut stone, while the tapered end produces a concentration of brilliance toward the tip.
The result is a stone that appears larger than its carat weight would suggest. At the same carat weight as a round brilliant, a pear cut presents roughly 10 to 15 percent more face-up surface area. This is because the elongated outline distributes the stone's mass differently rather than concentrating it in depth.
In a necklace, this visual effect is amplified. The stone sits against the skin and moves slightly with the wearer, which activates the brilliance across the full facet pattern.
The Length-to-Width Ratio
The proportions of a pear cut are described by its length-to-width ratio — the measurement of the stone's length divided by its width. Most pear diamonds fall between 1.45 and 1.75.
A ratio toward the lower end produces a softer, rounder silhouette. A ratio toward the higher end produces a more elongated, tapered shape.
For a necklace setting, ratios between 1.50 and 1.65 tend to read well against the neckline. Stones with very high ratios can appear narrow and are better suited to ring settings where the elongating effect on the finger is more pronounced.
There is no universally correct ratio. It is a matter of proportion relative to the setting and personal preference.
The Bow Tie Effect — What It Is and Why It Matters
All elongated brilliant cuts — oval, marquise, and pear — can exhibit what is known as the bow tie effect. This is a shadow that runs across the central width of the stone, roughly resembling the shape of a bow tie when viewed face-up.
The bow tie is caused by the geometry of elongated facets. Light entering from the sides of the stone is not fully redirected toward the viewer's eye, producing a darker band across the centre.
The presence of a bow tie is not a flaw in itself. All pear diamonds have some degree of it. What matters is the intensity. A strong, dark bow tie that remains fixed under all lighting conditions indicates a poorly proportioned cut. A soft, faint bow tie that shifts and disappears as the stone moves indicates a well-executed cut with normal light behaviour.
When viewing a pear diamond, look at the stone in motion — tilt and rotate it under a consistent light source. A well-cut pear will show the bow tie flickering and dissolving as the stone moves rather than remaining as a static dark band.
The Bellari pear diamond necklace uses IGI certified stones. Each certificate records the stone's cut quality, which is one of the primary factors that determines how the bow tie behaves.
Tip Up or Tip Down: Orientation in a Necklace
In a pear cut ring, the orientation of the stone — whether the point faces toward the fingertip or toward the palm — is a common question. For a necklace, the equivalent question is whether the tip should face upward toward the chin or downward toward the décolletage.
Both orientations are worn. There is no convention that overrides personal preference.
Tip pointing downward is the more common orientation for solitaire pendants. The tapered point draws the eye toward the centre of the neckline and creates a subtle lengthening effect on the neck.
Tip pointing upward can appear more unusual and creates a different visual balance. Some settings are designed specifically for this orientation.
In the Bellari pear diamond solitaire necklace, the stone is set with the tip downward. This is consistent with the most common pendant orientation and allows the stone's elongated silhouette to follow the natural line of the neckline.
Yellow Gold or White Gold: Choosing a Metal for a Pear Diamond Necklace
The Bellari pear diamond necklace is available in 18K solid yellow gold and 18K solid white gold. Both use the same stone — IGI certified, lab-grown, D to E colour, VS1 clarity.
The choice between yellow and white gold is primarily aesthetic, though the metal can subtly affect how the stone appears.
18K Yellow Gold
Yellow gold is warmer in tone. It does not affect the stone's colour grade, but the warm base can create a soft contrast against a D or E colour stone, making the white of the diamond appear slightly crisper by comparison.
Yellow gold has experienced a sustained return in fine jewellery over the past several years. In Australia, the preference for yellow gold has grown particularly in the solitaire pendant category.
18K solid gold contains 75 percent pure gold. This is the standard for fine jewellery. It is more durable than 24K gold and more valuable in gold content than 9K or 14K alloys.
18K White Gold
White gold is created by alloying yellow gold with white metals — typically palladium or silver — and is usually rhodium-plated to achieve a bright, neutral finish. Over time, rhodium plating can wear and may need to be reapplied, though this is a minor maintenance consideration.
White gold creates a more neutral visual pairing with a colourless diamond. The stone and setting read as a single unified piece rather than two contrasting elements.
Both metals are solid 18K gold. Neither is plated, coated, or filled. The difference is purely in the alloy composition and resulting colour.
Chain Length and Wearing Position
The Bellari pear diamond necklace is available in two chain lengths: 16 inches and 18 inches.
16-Inch Chain
A 16-inch chain sits at or just below the collarbone. On most necklines, this positions the pendant in the centre of the upper chest. It is the most common length for a solitaire pendant and works well as a standalone piece or worn over a high neckline.
18-Inch Chain
An 18-inch chain sits slightly lower, typically in the area just above the sternum. This is often described as a princess length and gives the pendant a little more movement. It reads well with open necklines and lower-cut tops.
Both lengths allow the pear diamond to sit comfortably and move naturally. The right length depends on where you want the stone to rest and the necklines you typically wear.
For reference, the Bellari size guide at bellari.com.au/pages/size-guide includes a necklace length visual that shows where each chain length sits on the body.
IGI Certification and What It Tells You
Every pear diamond in the Bellari collection is certified by the International Gemological Institute (IGI). IGI is one of the world's primary independent gemological laboratories and is widely recognised as the standard certification body for lab-grown diamonds.
The certificate records the stone's four primary quality characteristics:
Cut. For a pear shape, cut quality describes the precision of the facet arrangement, the symmetry of the outline, and the polish of each facet surface. A well-executed cut determines how efficiently the stone handles light.
Colour. The Bellari diamond necklaces use D to E colour stones. D is the highest colour grade — completely colourless. E is the next grade and is also colourless to all but a trained examiner under magnification. Both grades are at the top of the colour scale.
Clarity. The stones are graded VS1 (Very Slightly Included, first degree). VS1 stones contain inclusions that are very difficult to see even under 10x magnification. To the naked eye, VS1 stones are clean.
Carat weight. The certificate records the exact mass of the stone.
Beyond the four characteristics, each stone has its IGI certificate number laser-inscribed on the girdle — the thin band around the widest part of the stone. This number can be entered at igi.org to verify the certificate in full.
The laser inscription is a permanent marking that does not affect the stone's appearance and confirms that the physical stone matches the certificate. The inscribed number is not visible to the naked eye but is readable under jeweller's magnification.

How the Pear Cut Compares to Other Shapes in the Bellari Range
The Bellari lab-grown diamond solitaire necklace is available in four cuts: round brilliant, oval, pear, and emerald cut. Each produces a different visual character and different light behaviour.
This section describes how the pear relates to the other three cuts. It is not a ranking — all four are available in the same metal options and at similar price points.
Pear vs Round Brilliant
The round brilliant produces the highest overall brilliance of any diamond cut. Its symmetrical facet arrangement maximises the return of white light toward the viewer's eye. The round has no orientation preference and no bow tie effect.
The pear produces comparable brilliance with a different quality. The light return is concentrated more at the rounded base and along the tapered outline, giving the stone a slightly more directional sparkle. The elongated shape has a different visual weight on the neckline than the round.
Pear vs Oval
The oval and the pear are both elongated brilliant cuts. They have similar face-up surface areas at the same carat weight. Both can exhibit the bow tie effect.
The oval has two symmetrical rounded ends and a more continuous silhouette. The pear has the same rounded base but tapers to a point, which creates a more defined directionality. In a pendant setting, the point of the pear is visible as a distinctive feature. The oval reads as symmetrical from any angle.
The oval has seen strong sustained demand in Australia over the past several years. The pear is less common as a necklace stone, which gives it a distinctive quality.
Pear vs Emerald Cut
The emerald cut is a step cut rather than a brilliant cut. It has a smaller number of larger, flat facets arranged in a rectangular outline with cropped corners. It produces a different type of light interaction — a slower, gliding flash rather than the rapid multi-directional sparkle of a brilliant cut.
The emerald cut has a clean, architectural quality. The pear has more dynamic brilliance. They suit different aesthetic preferences and different necklines.
For buyers deciding between cuts in the Bellari solitaire range, both the lab-grown diamond solitaire necklaces collection and the individual product pages include photography of each cut in both metal options.
About Lab-Grown Diamonds
Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds. They are composed of pure carbon in the same crystalline structure (cubic) and share the same optical properties — the same refractive index, the same dispersion, the same hardness (10 on the Mohs scale).
They are grown in controlled laboratory environments using two established methods: High Pressure High Temperature (HPHT) and Chemical Vapour Deposition (CVD). Both methods reproduce the conditions under which natural diamonds form.
A lab-grown diamond and a mined diamond cannot be distinguished visually — not by the naked eye and not by a standard jeweller's loupe. The distinction requires specialised equipment that detects trace growth patterns specific to laboratory growth.
The Bellari moissanite vs lab-grown diamond guide covers the distinction between lab-grown diamonds and moissanite in full for buyers considering both materials.
The Bellari Pear Diamond Necklace
The Bellari pear diamond solitaire necklace is made to order. Each piece is assembled from its components after an order is placed rather than held in pre-made inventory. This affects lead times but not the stone or setting quality.
The stone is IGI certified, D to E colour, VS1 clarity. It is set in a fine claw setting that holds the pear diamond at the girdle and protects the tip — the point of a pear cut is the most vulnerable part of the stone and should always be held by a claw or bezel at the apex.
The chain is solid 18K gold, matching the setting. Both yellow gold and white gold options are available.
The necklace is designed in Sydney. Every certificate number is laser-inscribed on the stone and verifiable at igi.org.
The pear diamond necklace in 18K yellow gold and the pear diamond necklace in 18K white gold are available on the Bellari website.
Caring for a Pear Diamond Necklace
Lab-grown diamonds are as hard as mined diamonds (Mohs 10) and require the same basic care. The following applies to the pear diamond necklace and to all Bellari diamond pieces.
Clean the stone and setting with warm water, a small amount of gentle dish soap, and a soft brush. Work gently around the claw setting and rinse thoroughly. Pat dry with a lint-free cloth. Avoid ultrasonic cleaners if the necklace has any inclusions near the surface — VS1 stones are generally safe, but regular cleaning with a soft brush is sufficient and lower risk.
Store the necklace flat or hanging to prevent the chain from knotting. Keep it separate from other jewellery to avoid surface scratching.
18K solid gold is durable for daily wear but can develop fine surface scratches over time. A jeweller can re-polish the setting if needed. White gold may require rhodium replating over years of wear.
The chain's lobster clasp should be checked periodically for any signs of wear at the closure. Any movement or play in the clasp mechanism is worth addressing before it becomes a loss risk.
Summary
The pear cut is one of the most distinctive shapes available in the Bellari lab-grown diamond range. Its elongated silhouette, concentrated brilliance at the tip, and visible asymmetry make it different in character from the round, oval, and emerald options in the collection.
When choosing a pear diamond necklace, the primary factors are: the length-to-width ratio of the stone, the quality of the cut (which determines how the bow tie behaves), the claw protection at the tip, the metal and chain length, and the IGI certification.
All Bellari pear diamond necklaces use D to E colour, VS1 clarity stones with IGI certification, set in solid 18K gold.
The collection is available at Diamond Solitaire Necklaces
Frequently Asked Questions
What is the best length-to-width ratio for a pear diamond necklace?
Most pear diamonds for pendant use fall in the range of 1.50 to 1.65. This produces a stone that reads as clearly elongated without appearing narrow. Ratios below 1.45 appear rounder and fuller. Ratios above 1.70 appear very elongated and are less common in necklace settings. The right ratio depends on personal preference and the size of the stone.
Does a pear diamond necklace suit all necklines?
The pear cut pendant works well with open necklines — V-necks, scoop necks, and off-the-shoulder styles allow the stone to sit against the skin and move freely. A 16-inch chain suits higher necklines by positioning the stone just below the collarbone. An 18-inch chain gives more clearance and works well with lower necklines. Crew necks and high-neck tops do not leave room for a pendant to sit comfortably.
What causes the bow tie in a pear diamond and is it a problem?
The bow tie is a shadow across the centre of the stone caused by light entering from the sides of an elongated brilliant cut that is not fully redirected toward the viewer. A soft bow tie that shifts when the stone moves is normal and expected in a well-cut pear. A strong, fixed bow tie indicates poor proportions in the cut. Check the stone by tilting and rotating it under consistent light rather than viewing it from a single fixed angle.
What does IGI certification mean for a pear diamond necklace?
IGI (International Gemological Institute) certification means the stone has been independently assessed by a third-party gemological laboratory. The certificate records the cut, colour, clarity, and carat weight. For the Bellari pear diamond necklace, each stone is D to E colour and VS1 clarity. The certificate number is laser-inscribed on the stone's girdle and is verifiable at igi.org. This allows independent confirmation that the physical stone matches its paperwork.
Is a lab-grown pear diamond the same quality as a mined pear diamond?
Lab-grown and mined diamonds are chemically, physically, and optically identical. Both are pure carbon in a cubic crystalline structure. Both receive the same grading standards from gemological laboratories including IGI and GIA. A lab-grown pear diamond at D colour, VS1 clarity is graded to the same standard as a mined diamond at those grades. The difference is origin, not material composition or optical properties.
What chain length should I choose for a pear diamond necklace?
The Bellari pear diamond necklace is available in 16-inch and 18-inch lengths. A 16-inch chain sits at the collarbone and positions the stone in the upper chest area. An 18-inch chain sits slightly lower, above the sternum. Both are common lengths for solitaire pendants. The choice depends on where you want the stone to rest and the necklines you most often wear. The Bellari size guide at bellari.com.au/pages/size-guide shows where each length sits on the body.
How do I care for an 18K gold pear diamond necklace?
Clean the stone and setting with warm water, a small amount of gentle dish soap, and a soft brush. Rinse thoroughly and dry with a lint-free cloth. Avoid ultrasonic cleaners for routine maintenance. Store the necklace flat or hanging to prevent chain tangling. Keep it separate from other pieces to avoid surface contact scratching. 18K gold is durable but will develop fine surface scratches with daily wear — a jeweller can re-polish the setting periodically.
Can a pear diamond necklace be worn every day?
Yes. The stone is diamond (Mohs 10), the setting is 18K solid gold, and the chain is matched 18K solid gold. All of these materials are appropriate for daily wear. The claw at the tip of the pear should be checked periodically as it is the point most likely to catch on fabric or experience wear. Routine checks by a jeweller once a year are sufficient for most wearers.
