Columbia Gem House – Australian Sapphire Arch Cabs

Available in both calibrated and freeform sizes ranging from 1/3 to 2 carats, these Australian sapphire arch cabs are uniquely different, displaying the natural patterns created when the sapphire crystals were formed. Cabs are cut in calibrated sizes such as 6 mm x 2 mm, 7 mm x 2 mm, and 8 mm x 2.5 mm with varying heights. Responsibly sourced, the cabs are treated in-house by Columbia Gem House with heat only.
