Loose Aquamarine, Starbrite Cut, 7.97-carat Gemstone Like many other gemstones: carat, color, cut, and clarity come into play when determining aquamarine gemstone value. Our example is formed into a rectangular starbrite cut by the lapidary of Chris Wolsfburg, South Carolina, US. The cut enhances the luminous effect of this pale, true blue stone. From images, slight inclusions are visible, confirming the natural origins of the gem. This assessment is based on images only, but the color, natural clarity, provenance, and review of auction results of similar-sized stones will elevate the price request for this stone. Stone weight: 7.97ct. Measurement: 12.9mm x 13mm x 6.2mm.
