0.39 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 0.39 carat sapphire presents an emerald cut outline measuring 5.37 by 3.42 by 2.23 millimeters, executed with a mixed brilliant faceting scheme that marries the crisp rectangular geometry of an emerald shape with a pavilion and crown arrangement optimized for scintillation and color return. The cutter has employed truncated corners and well defined facet junctions to preserve structural integrity while enhancing light performance. Crown facets are proportioned to introduce controlled brilliance, while pavilion facets are angled to deepen the blue saturation without creating windowing, producing an overall visual balance between flash and body color. Clarity is assessed as very very slightly included at eye level, indicating microscopic inclusions that do not detract from face up transparency, and polish quality is excellent, with mirror smooth facet planes that maximize luster. Color is described as vivid in intensity, a highly desirable grade for Ceylon sapphires, and the piece has undergone standard heat treatment to stabilize tone and clarity. Origin is Ceylon Sri Lanka, a provenance that is historically associated with lively, clean blues and strong resale interest among connoisseurs.

From an investment standpoint this sapphire embodies attributes that collectors and knowledgeable buyers prioritize, namely vivid color, superior cutting, and Ceylon origin, all of which support long term desirability. While the stone is modest in carat weight, the combination of an exemplary face up color grade and precise mixed brilliant cutting enhances its effective color presence, allowing it to command a premium relative to lesser cut or weaker colored stones of similar size. Heat treatment is widely accepted in the trade when disclosed and correctly executed, providing stability and predictable performance, and natural origin distinguishes it from lab grown alternatives. Market dynamics for quality natural sapphires have shown steady appreciation driven by constrained supply of top color material and growing demand for certified, well documented gems suitable for bespoke jewelry. The Natural Sapphire Company provides provenance and quality assurance that improve liquidity and buyer confidence, and we advise preserving the stone in a secure mount and obtaining appropriate documentation to support future valuation. No investment is guaranteed, but a finely cut, vividly colored Ceylon sapphire with exacting craftsmanship is positioned to maintain and potentially appreciate in market value as a specialist collectible within the colored gemstone segment.
