The natural unheated Burma rubies are a vivid red color, they are estimated to weigh 3.74 cts.

This clip was made so that it could be worn on fabric or in the hair as a barrette. The double stems in the back are slightly curved so that they can both slide through fabric smoothly, and comfortable and easy to wear in the hair. The clip is also slightly curved so that it will hold any thickness of hair or fabric. The two pinstems squeeze together and each fit into its own holder making the barrettes quite comfortable.

The two chains meet at the corners of the rectangular platinum pendant, which is set with fifty-four bright white Old European cut diamonds that total approximately 2.25 carats.

Suspended from the pendant is a translucent, rich emerald-green GIA-certified jadeite jade carving that is significantly older than the necklace as a whole. This jade amulet...
