1.08 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This loose sapphire is a precise specimen ideally suited to custom jewellery design, weighing 1.08 carats, and displaying an asscher octagon outline with finished dimensions of 5.86 by 5.46 by 3.32 millimetres. The cutting style is faceted with a classic asscher step faceting arrangement, and the stone is described as transparent with intense yellow colour intensity and an excellent polish. Clarity is graded as very slightly included when evaluated at eye level, which indicates clean face up appearance with minor internal features that do not interrupt the geometric light pattern. The length to width ratio of approximately 1.07 yields an almost square presentation that preserves the asscher identity while offering a subtly elongated look suitable for a variety of mounting orientations. The depth measures 3.32 millimetres, which gives an overall depth proportion of approximately 58.7 percent relative to the mean of the length and width, a proportion that balances table size and pavilion depth to support strong optical contrast and disciplined light return. Origin is Ceylon Sri Lanka, and the stone has been heat treated to improve internal colour saturation and clarity stability, a standard enhancement that is widely accepted in the trade.

The asscher cut is a step cut characterised by concentric square or octagonal tiers on the pavilion and a series of parallel facets on the crown, producing a hall of mirrors effect, and this sapphire exemplifies those optical mechanics. The faceting schema concentrates on broad pavilion steps and a restrained table to create alternating flashes of light and dark that enhance the perception of depth and colour zoning. Because the pavilion and crown facets are larger and flatter than in brilliant cuts, the asscher style emphasises body colour, so an intense yellow of this quality reads vibrantly and uniformly across the table. The excellent polish produces sharp facet junctions and minimal surface milling, which improves specular reflection and reduces light leakage. The clarity level described as very slightly included indicates that inclusions are minor and generally restricted to internal crystal features or minute feathers that do not intersect major facet junctions, preserving overall symmetry. The combination of precise faceting, refined polish, and Ceylon provenance yields a transparent, saturated face up that is both technically impressive and visually engaging.

For custom jewellery applications the dimensions and shape of this sapphire make it exceptionally versatile, and its near square asscher form is particularly well suited to solitaire rings, halo settings, three stone configurations, pendant focal points, and bespoke stud or drop earring designs. At 1.08 carats and roughly 5.8 millimetres across, the gem fits classical four prong crowns with reinforced corner prongs to protect the cropped corners, or it can be set in a low profile bezel with discreet notches to allow light ingress while offering superior corner protection. The asscher silhouette also lends itself to east west orientation in elongated ring profiles, and it pairs elegantly with small melee diamonds on a pavé gallery or with tapered baguette shoulders for a tailored Art Deco aesthetic. Metal selection will further tune the visual effect, with warm yellow gold amplifying the saturated yellow tone, rose gold adding warmth and vintage character, and white metals providing a contemporary contrast that isolates colour for modern minimalistic presentations. Because the step cut renders broad facets, setters should focus on tight seat tolerances and precise prong placement to preserve the hall of mirrors effect and to avoid light leakage at facet junctions.

From a practical standpoint this sapphire carries the durability advantages of corundum, and it responds well to normal wear when set with appropriate protection for the corners and girdle. The heat treatment applied during enhancement is stable under normal jewellery manufacturing and routine wear, but standard care recommendations apply, including avoiding high thermal shock and aggressive ultrasonic cleaning if the mounting is compromised. The excellent polish and precise facet symmetry produced by skilled lapidary work ensure consistent light performance, and The Natural Sapphire Company can provide additional photographic angles and specific mounting guidelines to ensure optimal visual outcome in your bespoke design. For clients seeking exacting technical information during the design phase, we can supply precise diagrams of the pavilion and crown proportions, guidance on recommended prong or bezel profiles, and compatibility notes for common head types used by experienced jewellers. If you are planning a custom commission, this Ceylon asscher yellow sapphire is a technically refined and visually commanding choice that adapts well to a range of settings while offering the colour intensity and geometric clarity that discerning buyers value.
