Another personal collection release that I will really miss but have enjoyed!

Unique geometric pendant on chain with three old mine cut diamonds, each around a third of a carat for 1 full carat total weight in diamonds. Crafted in 18k white gold. The shape is a sort of infinity symbol, with the three diamonds set into a triangle continuing to the swirling loop. The chain is about 15 1/2 inches long.

A great geometric look - perfect to dress up or down. And certainly a unique antique piece from the Art Deco period!

It has no hallmarks but was sold to me as 18k which is the standard in France and tested to confirm. It is possible it is platinum but I don't have a reliable test for that, but definitely a white precious metal.

Antique box / props not included. Please note the measurements as I have small fingers and it can be difficult to determine scale from pictures.


Each diamond is about 4.3mm for a total of 1 carat. The pendant is 19x14mm to the attached loop not including the jump ring. It is 3.3mm deep. The pendant and the chain each weigh 2.4 grams.


The diamonds are eye clean with just faint speck inclusions seen only under strong magnification, so a very nice clarity considering age and what we typically see in antique diamonds. Very secure in the milgrain bezels, this one is ready for regular wear. No chips, nicks or any damage to the stones. Very slight warmth also typical for the period with a very nice sparkle. Some patina to the chain which is a bit dainty.

But of course Due to age, please note this is not a mint condition item.
