Product Details

A fancy vivid yellow is the highest colour grade a yellow diamond can reach, and it is rare in both natural and lab-grown stones. Romi centres a 1.5ct oval in this grade in 18k yellow gold, where the warm setting draws out rather than competes with the stone's saturated colour.

Nine smaller oval lab-grown diamonds wrap the band, catching light at the sides and drawing the eye back to the vivid yellow centre. The total diamond weight across the ring is 2ct.

Fancy Vivid Yellow / VS2, IGI certified (698529248). Ready to wear from Newcastle, with Designed and made by Matthews Jewellers, Newcastle. Fine jewellers since 1957.
