50 Carat Vintage Santa Maria Aquamarine Pendant 18k

This Art Deco pendant necklace centers a 50 carat emerald cut Santa Maria aquamarine set in an ornate frame mounting with a Mid-Century 18 karat yellow gold addition that connects to a 24-inch box chain.

The aquamarine displays the prized deep blue color characteristic of Santa Maria stones from Brazil, while the emerald cut's step facets emphasize the stone's clarity and color saturation rather than maximum sparkle.

Surrounding the aquamarine are .80 carats of diamonds in a mix of single and round brilliant cuts, set in channel and bezel settings with G color and VS2-SI1 clarity.

The yellow gold frame creates warm contrast against the cool blue aquamarine. Milgrain edge detailing adds beaded texture along the metal edges, typical of Art Deco craftsmanship. The pendant hangs from a box chain with a spring ring clasp, and the substantial 50 carat aquamarine gives this piece significant weight and presence when worn.
