6.33 Ct. Bi Color / Parti Sapphire Crystal from Ceylon (Sri Lanka)

One beautiful translucent 6.33 carat various shape bi color parti sapphire is presented with precise dimensions of 18.79 by 8.36 by 6.81 mm, cut in a crystal cutting style that embraces a rough crystal cut aesthetic, finished to an excellent polish, and showing intense color intensity with no enhancement, originating from Ceylon Sri Lanka. The crystal cut preserves natural crystal planes while creating reflective facets that catch light differently from traditional faceting, producing a play of tone and depth along the parti color zones. The translucency allows internal color zoning to read clearly to the eye without appearing overly included, and the excellent polish elevates surface luster so that each facet and natural plane contributes cleanly to overall brilliance. For the educated buyer, the combination of a rough crystal cut and a high quality polish signals an intentional choice to retain the stone character while optimizing light return, and the measured dimensions confirm a substantial presence suitable for statement pieces or bespoke design work.

Clarity is graded as Slightly Included, evaluated at eye level, which in the context of a natural Ceylon parti sapphire is an important indicator of authenticity and value, because inclusions of this degree are common in untreated stones and often provide evidence of natural growth and origin. Slightly Included means small features are visible to a trained observer at normal viewing distances, yet they rarely compromise the visual impact or structural integrity of corundum, a mineral that rates 9 on the Mohs hardness scale and is well suited to everyday wear. The fact that this sapphire is unheated and untreated enhances its desirability, as provenance from Sri Lanka, a historically significant source, often commands a premium among collectors and connoisseurs who value natural color and trace element signatures tied to specific mining regions. The Natural Sapphire Company stands behind this gem with transparent information about its grading, cutting style, and origin, and can assist with independent certification, bespoke setting recommendations, and conservation advice, ensuring that the buyer understands both the technical attributes and aesthetic advantages that make this 6.33 carat bi color parti sapphire a distinctive and enduring addition to a curated collection.
