Helga Rainbow Sapphire Princess Cut Bracelet

The piece

Fifteen carats of princess-cut sapphire running the full color range, channel-set at 5.3mm across 6.5 inches on 18.45 grams of 14K gold. A rainbow line is the hardest color bracelet to get right — the sequence has to move evenly through the spectrum, and one stone out of order reads as a mistake rather than a gradient. Channel setting keeps the surface flat and the stones protected, which matters more on a piece carrying this much stone across a relatively short length. More across our women's collection .
