Choosing your diamond

F colour or higher and VS1 clarity or higher, with most diamonds in the VVS range. Each is individually assessed to appear colourless and eye-clean.

We assess the outline, proportions, symmetry and light performance individually. Fancy shapes are selected by eye alongside their independent grading documentation.

Carat measures weight, rather than exact visual size. Your diamond’s grading documentation, precise measurements and close-up video are presented for approval before setting.

For personal guidance on diamond size, proportions or metal, speak with our client care team.

Chain & length

Included with your pendant
16–18 inches (40.6–45.7 cm) · adjustable · 1mm cable chain. Recycled solid gold.

The adjustable chain lets you wear the pendant at a shorter or longer length within the 16–18 inch range. How it sits will depend on your neck, proportions and neckline.

Find your preferred length
Place a piece of string around your neck where you would like the pendant to sit, then measure the string. For layering, allow space between your necklaces.

For another length or help choosing, speak with our client care team. We will confirm availability and any price difference before you order.
