Design Details

Our Alexandra three-stone sapphire & diamond engagement ring is one of our most popular signature designs. Inspired by a beautiful antique piece that Dana & Rad saw at a Christie's auction years ago, they refined the design for a new generation of fine jewelry lovers. Alexandra is typically made to order (ships in 3-6 weeks), but we've decided to make this design available as a Ready to Ship selection (ships in 2-3 business days).

An intensely-hued cushion cut lab sapphire is flanked by two half-moon diamonds and set in eco-friendly 14K white gold for a breathtakingly luxe construction at an amazing value. 

About Lab Sapphires

Lab grown sapphires are optically, chemically, and physically identical to their natural counterparts. The main difference between lab grown sapphires and natural sapphires is where they are formed (laboratory vs. within the earth) and the amount of time it takes for them to form (expedited timeline vs. millions of years). The expedited and optimized conditions for growing lab gems creates an amazing opportunity for fine jewelry lovers looking for durable and clear stones at an attractive price point.

Alexandra is just breathtaking when paired with our Constance wedding band, as shown in Photo #4 above.

To commission a natural sapphire version of Alexandra, pricing starts at approx. $25,000 - $30,000. Email Dana & Rad at to make a formal inquiry.
