3 Carat Old Mine Cushion Blue Color Lab Grown Diamonds

A 3 carat blue old mine cushion has a deep, contemplative blue quality expressed through broad, vintage faceting. At 3 carats, the chunky blue flashes create a dramatic, sapphire-like presence with the old mine cushion's distinctive antique character.

The broader facets create chunky, saturated blue flashes rather than scattered sparkle. At 3 carats, each flash is substantial and deeply colored. The vintage cutting gives the blue a contemplative depth that modern cuts express differently.
