0.80 Ct. Bi Color Sapphire from Ceylon (Sri Lanka)

This transparent bi color sapphire weighs 0.80 carat, presented in a marquise shape with dimensions of 7.33 x 4.64 x 3.19 mm. The stone has been fashioned with a step cut that emphasizes linear facets and internal clarity, and it exhibits a light color intensity that allows nuanced color zoning to be visible without overpowering the overall appearance. Clarity is graded as very slightly included, evaluated at eye level, indicating faint natural inclusions that do not detract from the gem's transparency or structural integrity. The sapphire has received a professional heat treatment, a common and stable enhancement that improves color uniformity and clarity, and the finish is an excellent polish, providing crisp facet junctions and strong surface reflection.

The journey of this sapphire begins in the alluvial deposits of Ceylon Sri Lanka, where artisanal miners and local teams carefully recover rough material from river gravels and primary deposits. Each rough parcel is examined for potential, and this piece was selected for its pleasing bi color character and clarity. The rough was then processed and cut with an intention to preserve weight while maximizing optical performance, choosing a step cut and marquise outline to enhance the stone's inherent color transition and to create a slender, elegant profile. Following cutting, the rough was assessed for treatment suitability, and seasoned lapidaries applied a controlled heat treatment to stabilize and clarify the material, using industry standard protocols. Final cutting and polishing were performed with attention to facet symmetry and surface quality, producing the excellent polish noted in the finished gem.

Throughout this process, documentation and care were maintained to preserve provenance and quality, and The Natural Sapphire Company has retained records confirming origin, treatment, and the gem's measured specifications. The finished sapphire is suitable for precise jewellery settings where the marquise silhouette and subtle bi color quality can be showcased, and it offers a balance of natural character and technical refinement. Prospective use cases include a solitaire accent, a vertical pendant, or as a paired stone in a custom design, where its transparency, step cut, and light color intensity can be appreciated in both daylight and artificial light.
