0.78 Ct. Tourmaline from Ceylon (Sri Lanka)

This transparent 0.78 carat oval greenish brown tourmaline measures 7.00 x 5.10 x 3.40 mm and is presented by The Natural Gemstone Company, offering a finely proportioned gemstone with clear visual presence. The gem has a mixed brilliant cut that balances larger table facets with a faceted pavilion to optimize light return and scintillation. Clarity is graded as very slightly included evaluated at eye level, which translates to an appearance that is effectively eye clean under normal viewing, preserving strong transparency and allowing the stone to read as luminous and clean when set. Color intensity is medium, and the hue sits in a versatile greenish brown range that responds well to both warm and neutral metals, while the polish is excellent, giving crisp facet delineation and surface luster. This tourmaline is natural and untreated, with no enhancement, and its origin is Ceylon Sri Lanka, a well regarded source for quality colored gemstones.

The combination of size and clarity makes this stone particularly well suited to a statement piece, as the 7.00 x 5.10 mm oval footprint offers a noticeable yet wearable silhouette that centers attention without overwhelming the design. At 0.78 carat the gem possesses a meaningful heft for a single center stone in a ring or pendant, and the very slightly included clarity grade ensures that light passes through the pavilion to produce consistent brilliance and color dispersion. The mixed brilliant cut enhances sparkle while maintaining the classic elongated oval outline that flatters the finger and creates the perception of greater size. The excellent polish further amplifies the gem s presence by delivering strong surface reflection and clean facet junctions.

For design considerations this tourmaline is appropriate for a refined solitaire setting when the objective is a clear, focused statement, or for a halo configuration when a bolder visual impact is desired. A minimal prong setting will maximize light exposure and brilliance, while a low bezel can be specified for additional protection without obscuring the stone s character. The natural, unenhanced origin from Ceylon Sri Lanka adds provenance that complements the gem s optical attributes, making this piece a considered choice for collectors and designers seeking a singular, well proportioned center stone.
