Here's a total one of a kind necklace. Of course, the bezels are all handmade - 18kt yellow gold. The chain is rosy, pinky, pink gold.

So, let's go over the stars of the show, the diamonds. They're from a parcel of multi-colored Natural Fancy Colored Diamonds.

The stones are all roughly 3mm x 2.5-3mm. The oval is 3.7 x 2.4mm. Starting from the left (my grades - there are no GIA reports)
Cushion Modified Brilliant Fancy Light Pink I1
Cushion Modified Brilliant Fancy Deep Orangy Yellow SI1
Cushion Modified Brilliant Fancy Deep Orangy Brown SI2
Oval Modified Brilliant Light Brownish Pink I1
Cushion Modified Brilliant Fancy Deep Orangy Brown SI2
Cushion Modified Brilliant Fancy Light Brownish Pink VS2
Cushion Modified Brilliant Fancy Deep Brownish Purple SI2

All the stones have their own appeal. The oval is clearly the center point, but the pink on one end and the purple on the other end draw your eye back and forth. The contrast weight the orangy browns is so kewl!!

Credit Sandra with the entire piece. She envisioned it and picked the diamonds. She made the purchase of the parcel. And told our bench how to make it. Hats off.
