What a joy this Art Deco Diamond trilogy ring is, sparkling brilliantly in every direction! 

A lovely large Diamond sits centre stage in a square setting with two Diamonds either side in circular settings, all atop a wonderfully tall, architectural gallery that the Art Deco era was so fabulous at designing! 

The Diamonds are a wonder to behold, shimmering and glittering magnificently in all directions! 

What a stunning engagement ring this would make... and it stacks with other antique and vintage ring superbly as well!
