4.49 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 4.49 carat cushion shape blue sapphire presents a rare combination of size, symmetry, and optical performance that will immediately appeal to the educated buyer and the bespoke jeweller alike. The gem measures 10.09 by 8.15 by 6.17 millimetres, a proportion that gives it a commanding table and a strong presence in any ring or pendant. Cut in a mixed brilliant style, the pavilion and crown facets are arranged to balance depth and sparkle, producing both strong light return and attractive scintillation. The clarity is graded as very very slightly included, evaluated at eye level, which means that while minute inclusions may be detected under high magnification, the stone appears essentially clean to the naked eye and offers unobstructed color and sparkle. The polish is excellent, with crisply finished facets that enhance brilliance and contrast without distracting surface graining.

Color and origin are central to a sapphire’s value, and this stone’s vivid blue saturation is emblematic of fine Ceylon sapphires from Sri Lanka. Ceylon origin is synonymous with a lively, saturated blue that often leans toward a clear, velvety tone rather than an overly dark appearance. This gem has been heat treated, a standard and widely accepted enhancement in the trade that stabilises and intensifies colour while preserving the original crystal structure. Heat treatment, when properly executed, is permanent and does not detract from durability. For the discerning buyer, the combination of vivid colour, transparent clarity, and Ceylon provenance creates a profile that is both attractive and historically desirable in the market.

From a design perspective this cushion shape sapphire is especially well suited to custom jewellery. The dimensions are ideal for a centerpiece on an engagement ring, offering visual impact without becoming impractically large for daily wear. The cushion outline, with rounded corners and a broad table, is forgiving for bezel and halo settings, yet also complements classic four or six prong designs that lift the gem to capture light. The mixed brilliant cut further aids versatility, because the balance of step and brilliant facets provides both depth of colour and lively reflection, which translates beautifully whether set in platinum, 18 carat yellow gold, or rose gold. For clients wanting maximum perceived size, a minimal bezel or elevated prong mount will showcase the table and allow the pavilion facets to perform. For those prioritising protection, a low bezel or closed gallery will shield the corners while still permitting side light through carefully placed apertures. This gem also pairs exceptionally well with a diamond halo, where high quality melee can provide contrast and increase the visual size without obscuring the sapphire’s vivid hue.
