Cushion cut sapphire 3 stone engagement ring with side trapezoids


Please complete all fields.

Natural sapphires are sourced from mines using traditional methods while cultured sapphires are grown from a seed under conditions that replicate the underground creation process. Both are physically, chemically, and optically the same.

A gift as brilliant as the sun - that is our Alamina.  On her you will find a breathtakingly beautiful cultured 2.75ct yellow or blue sapphire that is paired with sparkling white trapezoid (0.46ct) side diamonds (F VS1 grade) that is all set on an elegantly classic band. She comes in your choice of white gold, yellow gold or platinum and also various colored sapphires.  Handmade in NYC.

Also shown below with a radiant cut diamond - cost listed below does not pertain to this version of the design

Quality Gemstones

Natural mined sapphires
We hand select independent lab-certified sapphires that exhibit the best combination of color, brilliance, and value. Each sapphire is reviewed by a KDD staff member to ensure that it is eye-perfect - no visible inclusions to the unaided eye. For blue sapphires, we look for a top grade ceylon blue color. For Yellows, we prefer a nice medium color.

Cultured sapphires
Cultured sapphires are cultivated under the same environmental conditions as natural sapphires to produce excellent quality sapphires that are physically, chemically and optically identical to their natural counterparts. They are visually indistinguishable from those found in nature and an option to consider for their durability and beauty. Standard color options are Ceylon blue or medium yellow.
