How can I assess the quality of a cut tourmaline—especially in terms of cut, color, clarity, and value?

Cut Quality:

This lot features cushion cut and emerald cut stones. Both are highly sought-after shapes—cushion cuts enhance brilliance with rounded edges, while emerald cuts highlight clarity with elegant step facets. These cuts make the stones ideal for jewelry pieces that showcase both brilliance and depth.

Color Value :

The stones are a vivid green, which is one of the most desirable and valuable colors in Tourmaline. Green tourmaline from Afghanistan often displays lively, bright tones that hold strong appeal in both collector and jewelry markets.
Clarity
The clarity ranges from eye clean to slightly included. This means most stones will appear clean to the naked eye, with only minimal inclusions visible under magnification. For green tourmaline, this level of clarity is excellent, as the vibrant color masks slight inclusions effectively.

Weight, Size & Dimension :

The lot weighs a total of 64 carats with 39 pieces ranging from under 1 carat up to 3.85 carats each. Dimensions span 12.5×6.5×3.2 mm to 4.2×3.5×3.3 mm, making these stones versatile for a variety of jewelry settings, from rings and pendants to matched pairs for earrings.
 

Origin & Treatments:

These stones are from Afghanistan, a renowned source for high-quality green tourmaline. They are 100% natural and untreated, which increases their value and appeal compared to heat-treated or enhanced stones.
