1.73 ct Blue Aquamarine - Marquise

At 1.73 carats, this aquamarine from Brazil carries its blue color through a marquise cut, measuring 15.5 x 6 x 3.7 mm.

Aquamarine is the blue beryl, colored by iron, and grows in larger clean crystals than its cousin emerald, which is why it cuts so bright. Brazil has been one of the most prolific colored-gemstone sources in the world for a century, and still turns up new material on a regular basis.

A genuine aquamarine at a size and price you can actually wear, the real thing rather than a machine-grown copy. Hand-selected and photographed by Caveman Gems in good light, shown as honestly as a screen allows.
