3.68 ct Rare Santa Maria Aquamarine and Diamond 18K Ring

Write a Review

Simply the best... This is a rare Aquamarine, direct from the famous Santa Maria mine in Brazil.  Santa Maria aquamarines are the finest in the world.  Aquamarine quality is based primarily on color.  The more the saturation, the more the value.  This one is AAA - the very best.

This is about as perfect an aquamarine as you can get - the carat weight is perfect - 3.68 carats; the color is the perfect Santa Maria Aquamarine color - brilliant blue, with a very slight green influence; the cut is perfect, a custom fancy 12-sided oval cut by a master European lapidary - just gorgeous!   The best of the best aquamarine gemstones are called "double blue".  This one is the rare double blue.  Most AAA (best quality) aquamarines will be listed as "Santa Maria color", meaning their color is like a Santa Maria aquamarine - close, but... no.  This is the real thing.  If you like aquamarines, you cannot get any better than this one.  Whether you wear it on your right hand or left, it's an heirloom quality piece.

We put this ring in our setting design that we think properly showcases it - 18K white gold which we satin finished for that extra designer touch (please note: we can polish this setting shiny if requested).  The setting has 4 larger, .10 carat diamonds (2 on each side of the aquamarine) with diamonds on the setting basket.  Our settings are made with quality.  We took the photos for this ring in sunlight - but to see the sparkle, please check out the video (link above).
