7.31 Ct. Green Tourmaline from Ceylon (Sri Lanka)

This transparent 7.31 carat oval green tourmaline from Ceylon, Sri Lanka, is cut to precise proportions at 13.24 x 10.05 x 8.56 mm, and it stands apart from common market offerings by marrying size with remarkable optical performance. The faceted mixed brilliant cut was chosen to maximize fire and brilliance while preserving the depth of the intense green color. Where many tourmalines on the market are either heavily included, treated to alter tone, or cut conservatively to preserve carat weight, this stone is eye clean at normal viewing distance, has no enhancement, and has an excellent polish that lets every facet return light with clarity and life. The combination of a larger weight, a refined oval outline, and a mixed brilliant cutting style makes this gem read as a centerpiece rather than a mere accent stone, allowing it to command attention in any setting.

When compared to typical commercial tourmalines, this piece offers clear advantages in quality, value, and uniqueness. Many alternatives at similar sizes are either heat treated, oiled, or show lower clarity grades, which diminishes long term value and optical appeal. Synthetic options can mimic color but lack the natural origin and subtle zoning that make natural Ceylon tourmaline desirable. The precision of the mixed brilliant cut on this gem delivers more scintillation and dynamic light return than standard step or low angle cuts, offering a visual impact closer to gemstones with higher refractory indices. For collectors and jewelers seeking an investment quality stone, this tourmaline is an exceptional proposition because it combines natural origin, unenhanced state, eye clean clarity, intense color intensity, and meticulous finishing. At The Natural Gemstone Company we prioritize stones that balance beauty and integrity, and this oval green tourmaline exemplifies that standard, performing as a striking centerpiece for high end jewelry or a standout addition to a curated collection.
