6.06 Ct. Yellow Sapphire Crystal from Ceylon (Sri Lanka)

This listing describes a single semi translucent yellow sapphire weighing 6.06 carats, presented in a various shape form, with exact dimensions of 20.26 x 6.93 x 6.36 millimetres, a rough crystal cut, a clarity grade of very slightly included evaluated at eye level, medium color intensity, an excellent polish, no enhancement, and an origin of Ceylon Sri Lanka. These baseline specifications establish both the physical presence and the untreated nature of the stone. The 6.06 carat weight paired with the elongated proportions produces a significant visual length relative to depth, a characteristic that influences both light performance and the selection of mounting style. The rough crystal cut indicates that the stone retains much of its natural crystal habit with minimal faceting intervention, an approach that prioritises shape integrity and natural surface planes rather than maximal faceted brilliance. The clarity observation recorded as very slightly included at eye level indicates that the stone presents as essentially eye clean for most viewing distances, while internal growth features remain visible under magnification and when viewed from specific angles. The medium color intensity describes a balanced yellow tone that avoids the extremes of pale straw and saturated canary, offering versatility in design while remaining distinctly yellow in most lighting conditions.

The color grading and translucency of this sapphire demand particular attention for any technically minded buyer. Medium color intensity in a yellow sapphire typically represents an optimal zone for wearable stones because the saturation is sufficient to convey clear hue identity while permitting adequate light transmission to reveal internal structure. The semi translucent nature of this piece means that light diffuses through the crystal rather than reflecting in pinpoint facets, producing a soft internal glow and a warm, even color field. Observers will note that light leakage along the thinner planes enhances tonal uniformity, while the thicker central ridge exhibits slightly deeper saturation. Because the stone is unenhanced, the color is entirely natural and stable, derived from trace element chemistry native to Ceylon Sri Lanka. The clarity grade very slightly included specifies that inclusions are limited in size and density and do not materially obstruct the overall color or form. These inclusions act as fingerprint features that confirm natural origin and are consistent with stones that have been worked minimally from a natural crystal, contributing to the character rather than detracting from the gem quality.

From a cutting and craftsmanship perspective the rough crystal cut of this sapphire is a deliberate aesthetic and technical decision. Rather than executing a full pavilion and crown faceting scheme, the cutter preserved the terminal crystal planes and angled edges, refining the surface to an excellent polish without introducing a dense array of faceting. This treatment preserves growth patterns and natural terminations, and requires advanced lap work to achieve uniformly smooth facets and apexes while removing only minimal surface perturbations. The excellent polish noted in the description ensures that any remaining natural facets display clean, sharp lustre and that the stone presents minimal abrasive residue or polishing lines. For a stone measuring 20.26 millimetres in length with a maximum thickness of 6.36 millimetres, mounting recommendations typically prefer a bezel or partial bezel that protects the elongated profile and secures the thinner terminations, though skilled jewellers may incorporate partial prong work to display the crystal form. The elongated measurements also mean that when set with the long axis vertical, the stone will offer a slender visual silhouette ideal for pendants and drop designs, while on a horizontal axis the piece can read as an accent or centrepiece depending on the setting scale. The absence of enhancement simplifies long term care, as no heat treatment or diffusion requires special handling beyond standard sapphire maintenance.

Provenance and authentication are central to the value proposition offered by The Natural Sapphire Company, and this Ceylon origin yellow sapphire benefits from the established geological signature of Sri Lankan deposits. Sapphires from Ceylon commonly exhibit trace element combinations that favour light to medium yellow tones, and the presence of iron in controlled concentrations is typically responsible for the warm yellow chroma encountered here. The natural inclusions and preserved crystal habit provide corroborative evidence of origin and of the unenhanced status. For collectors and designers who prioritise natural character and documented provenance, this specimen presents a compelling option. Practical recommendations for care include cleaning in warm soapy water with a soft brush and avoiding harsh ultrasonic treatment if large internal fissures are present, although the very slightly included clarity suggests such risks are limited. The Natural Sapphire Company can provide additional imagery at magnification, independent third party assessment on request, and guidance on bespoke mounting to maximise the stone s visual orientation and structural security.
