oval lab grown diamond necklace 18K yellow gold Sydney Australia Bellari

Oval Diamond Necklace 18K Yellow Gold

From $1,980 AUD

Horizontal precision, centred around a single oval.

A single oval cut lab-grown diamond necklace, set in solid 18K yellow gold.

The stone is positioned east-west, sitting horizontally across the neckline. Four prongs secure the oval at its outermost points, holding the stone low and forward against the chest with its full face presented upward.

The chain is a considered detail in its own right. Fine and deliberately thin, it allows the stone to carry the piece entirely. Available in 14 inch and 16 inch, each with a 2 inch extender for adjustable wear.

Each diamond is individually selected and comes with IGI certification, verifying cut, colour, and clarity.

The oval, east-west. Considered in every detail.

This is a made-to-order piece, made with intention and care. Please allow a crafting time of 10–15 business days before shipping.
