2 Carat Old Mine Marquise Blue Color Lab Grown Diamonds

A 2 carat blue old mine marquise is a rare combination of fancy color and antique elongated cutting. The old mine faceting creates broad, deep blue flashes across the marquise's elongated body. At 2 carats, the blue appears richly saturated with the vintage light character that distinguishes old mine diamonds from modern cuts.

The old mine marquise's elongated body spreads blue across a wide face-up area, while the antique faceting produces deeper, broader flashes than modern cuts. At 2 carats, each flash of blue is substantial and contemplative rather than rapid and sparkly, creating a sapphire-like depth with diamond brilliance.

White gold or platinum maximizes the blue's intensity against a cool backdrop. Yellow gold creates a regal blue-and-gold contrast. Vintage settings with period details complement the old mine cutting heritage while the blue color makes the stone unmistakably distinctive and modern.
