The Costa Mesa Cocktail Ring. A shower of light and color that glows upon the hand, centered by a significant antique diamond weighing 2.15 carat. The chunky facets of the old European cut sprinkle light around with a delightful glimmer. 

The Art Deco multi gemstone design resembles the marquee of a 1920s Paris theater and has the drama to match. Meticulously hand crafted by our jeweler in platinum, French cut sapphires and emeralds in a most intriguing mosaic of gems. Even the under crown is detailed with filigree with the ring face having a multitude of milgrain. What a statement it would make for a bold engagement ring, too. This treasure's quality of the caliber of Cartier, Tiffany, Van Cleef or Buccellati would make for a marvelous heirloom.
