Round cut diamond studs. The clearest expression of the stone.
The round brilliant cut is designed around a single purpose: to return the maximum amount of light back through the face of the stone.
The Bellari Round Cut Diamond Stud Earrings set each stone in a four-prong basket in solid 18K gold. Both stones are matched for cut, colour, and clarity before leaving our studio.
Available in two total weights.
- The 1ct pair carries 0.5ct per earring, a proportional and versatile scale.
- The 2ct pair carries 1ct per earring, a more prominent presence that holds its position as the defining piece.
Each pair is accompanied by an IGI certificate verifying the cut, colour, and clarity of the stones. Set in solid 18K gold. Finished with a butterfly push back closure.
Round cut diamond studs. Precise, considered, worn daily.
This is a made-to-order piece, crafted with intention and care. Please allow a crafting time of 10 business days before shipping.

Frequently asked questions
The stone:
What is a lab grown diamond?
What is a lab grown diamond?
A lab grown diamond is a real diamond. It is pure crystallised carbon with the same chemical composition, hardness and optical properties as a mined diamond.
The difference is origin. A lab grown diamond is formed in a controlled environment rather than beneath the earth. Once cut and polished, the two cannot be told apart without specialist laboratory equipment.
Are lab grown diamond studs real diamonds?
Are lab grown diamond studs real diamonds?
Yes. Lab grown diamonds are recognised as diamonds by gemmological laboratories, including the International Gemological Institute (IGI). They rate 10 on the Mohs hardness scale, the same as any diamond.
What makes the round brilliant cut different?
What makes the round brilliant cut different?
The round brilliant is cut with 57 or 58 facets arranged around a circular outline. The proportions are designed to return as much light as possible through the top of the stone.
Of all diamond shapes, the round brilliant gives the most consistent brightness from every viewing angle. It is the most chosen shape for stud earrings for that reason.
How does a lab grown diamond compare to moissanite?
How does a lab grown diamond compare to moissanite?
They are different stones with different character. Diamond returns light as bright, white brilliance. Moissanite has a higher refractive index and greater dispersion, which shows as more coloured fire.
Diamond is also slightly harder, at 10 on the Mohs scale against 9.25 for moissanite. Bellari offers round studs in both. The choice comes down to which character you prefer.
Certification:
Do the diamond earrings come with a certificate?
Do the diamond earrings come with a certificate?
Yes. Each pair is accompanied by an IGI certificate verifying the cut, colour and clarity of the stones. The IGI is an independent gemmological laboratory, and its reports identify each diamond as lab grown.
What colour and clarity are the diamonds?
What colour and clarity are the diamonds?
Bellari selects diamonds graded D to E for colour and VVS2 to VS1 for clarity. D and E are the two highest colour grades, fully colourless. At VVS2 to VS1, any inclusions are not visible to the eye. The exact grades for your pair are recorded on the IGI certificate supplied with the earrings.
Are both diamonds in a pair matched?
Are both diamonds in a pair matched?
Yes. Both stones are matched for cut, colour and clarity before leaving our studio, so the pair reads as one.
Size and carat weight:
What does 1ct or 2ct total weight mean?
What does 1ct or 2ct total weight mean?
Total carat weight is the combined weight of both earrings. The 1ct pair carries 0.5ct per earring. The 2ct pair carries 1ct per earring.
How big are 0.5ct and 1ct round diamonds?
How big are 0.5ct and 1ct round diamonds?
A 0.5ct round brilliant measures approximately 5.1mm across. A 1ct round brilliant measures approximately 6.4mm across. Exact measurements vary slightly with each stone's proportions.
Should I choose the 1ct or 2ct total weight pair?
Should I choose the 1ct or 2ct total weight pair?
The 1ct pair, at 0.5ct per earring, is a proportional, versatile scale. It sits neatly on the lobe and suits daily wear, workwear and stacking with other piercings.
The 2ct pair, at 1ct per earring, has a more prominent presence and holds its position as the defining piece. If you wear one pair most days and want it to be noticed, the 2ct pair is the stronger choice.
Do 1ct studs look much bigger than 0.5ct studs?
Do 1ct studs look much bigger than 0.5ct studs?
Yes, noticeably. A 1ct round diamond is roughly 25% wider across than a 0.5ct stone, and its face is around 55 to 60% larger.
Setting, metal and wear:
What is a four prong basket setting?
What is a four prong basket setting?
Each diamond is held by four prongs that rise from a basket beneath the stone. The setting holds the diamond securely while leaving most of the stone open to light, so it returns more brilliance.
Are the diamond earrings solid gold?
Are the diamond earrings solid gold?
Yes. The earrings are set in solid 18K gold, which is 75% pure gold. They are available in yellow gold and white gold.
Should I choose yellow gold or white gold?
Should I choose yellow gold or white gold?
Yellow gold carries a warm tone that frames the diamond with clear contrast.
White gold carries a cool tone that blends with the stone, so the diamond reads larger and brighter at the ear.
Choose the metal that matches the jewellery you already wear.
What type of back do the diamond earrings have?
What type of back do the diamond earrings have?
The earrings are finished with a butterfly push back closure. It slides onto the post and holds firmly behind the lobe.
If you would prefer a screw back or another closure, contact our team at hello@bellari.com.au to arrange a custom option.
Can I wear diamond studs every day?
Can I wear diamond studs every day?
Yes. Diamond is the hardest gemstone, and solid 18K gold does not tarnish.
Remove the earrings before swimming and when applying lotions or perfume, and clean them gently with warm water and a soft brush.
Can I wear these studs in a second piercing?
Can I wear these studs in a second piercing?
Yes. The 1ct total weight pair, at 0.5ct per earring, is the more common choice for second and third piercings.
The 2ct pair is usually worn in the first piercing as the main stud.
