Round Blue Sapphire Solitaire Engagement Ring

The round is where sapphire looks most like itself: a deep, even blue that reads rich from across a room and settles clean on a slim tapered band. This center runs from 0.7 to 1.5 carat, hand-picked for a saturated royal-blue face and no cloudiness to the eye. Sapphire sits at 9 on the Mohs scale, just under diamond, so a solitaire you wear every day keeps its polish for decades. Choose lab-created for a cleaner, lower-priced stone or natural for an earth-mined one, then pick your metal and carat.

A note on color: natural blue sapphires are routinely heat-treated to even their tone. That is standard across the trade, and we treat it as normal rather than a flaw to hide.

Shown complete with a real Round blue sapphire center from 0.7 to 1.5 carat, your choice of a lab-created or natural blue sapphire, from $1,269 all-in. The price is the finished ring: setting, the sapphire center you choose, and the labor to set and size it. Sapphire is 9 on the Mohs scale, second only to diamond in hardness, so it wears beautifully every day. These calibrated stones ship without an individual lab report.
