8.35 Ct. Tourmaline from Ceylon (Sri Lanka)

This bluish green tourmaline presents as a precisely cut emerald cut weighing 8.35 carat, with exact dimensions of 12.50 x 10.19 x 7.58 mm, offering a length to width ratio of approximately 1.23 and a depth of 7.58 mm which corresponds to a depth percentage of approximately 67 percent. The emerald cut is executed as a classic step cut with broad parallel crown and pavilion facets, a generous table and neatly truncated corners, a faceting scheme that prioritizes color distribution and transparency over scintillation, producing broad flashes of even color and a calm, architectural appearance. Color intensity is classified as intense, the bluish green hue combining both cool blue undertones and a lively green saturation, the balance tuned to showcase complex trace element chemistry without overpowering brilliance. The gem was heat treated as an enhancement to refine and stabilize the saturation, a standard, controlled treatment in high quality tourmaline in order to reduce brownish overtones and to accentuate the blue green axis, performed to industry norms and resulting in a stable, durable color suitable for daily wear in fine jewelry or for display in a curated collection.

Clarity is graded as very very slightly included evaluated at eye level, indicating inclusions are minimal and do not impact transparency when viewed without magnification, while under loupe inspection a few minute pinpoint inclusions and very fine internal growth features may be visible but are well positioned away from critical facet junctions. The cutting demonstrates exceptional craftsmanship, with excellent polish yielding mirror sharp facet planes and crisp facet junctions, precise symmetry ensuring even facet alignment across the crown and pavilion, and a well executed girdle thickness that balances durability with light performance. The step faceting on the emerald cut deliberately reduces the visibility of typical tourmaline pleochroism by presenting large, consistent planes of color, yet the stone retains a subtle directional color shift under different lighting orientations, offering connoisseurs an additional visual nuance to examine with light. Optical clarity combined with the executed faceting allows the intense color to read as saturated and pure across the table and face up view, while the cutting preserves weight efficiently from the rough to yield a substantial 8.35 carat finished gem, a size that is rare for high clarity, intensely colored tourmaline of Sri Lankan origin.
