Uneek Round Blue Sapphire and Round Diamond Eternity Band

Divine duos of meticulously matched round blue sapphires alternate with solo round diamonds in this strikingly unconventional eternity band; crafted, this pretty piece is designed to go with your sapphire-and-diamond engagement ring, but looks gorgeous with an all-diamond ring, too; the model pictured here has 3.45 mm round sapphires and diamonds; there's 12 sapphires with a combined weight of 2.20 carats, and 6 diamonds with a combined weight of 0.90 carats; a version with slightly smaller stones is also available; from Uneek's Eternity and Royal Blue Collections.
