2.49 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent blue sapphire weighs 2.49 carats, and is presented in a cushion shape with precise measurements of 8.35 by 6.36 by 4.96 millimeters, and a resulting depth of about sixty seven percent relative to its girdle dimensions, and it exhibits an intense body color with a clarity grade recorded as very slightly included when evaluated at eye level, and the cutting style is a mixed brilliant which combines a faceted brilliant style crown with a stepped pavilion to harmonize light return and color saturation, and the piece has received heat treatment to enhance its intense blue hue, and polish is graded excellent, giving the facet planes a mirror like finish. The combination of weight and dimensions places this sapphire in a size class that balances face up color intensity with potential for high light performance when set in a ring or pendant, and the cushion outline with softly rounded corners maximizes surface area to emphasize the gem s saturated color while preserving a desirable depth for internal reflection, and provenance is Ceylon Sri Lanka, a source noted for bright, clean tones and lively blue character, and this example conforms to those regional expectations while offering the stability and consistency of standard heat enhancement practices.

The mixed brilliant cut is executed to optimize both brilliance and color retention, and the crown carries a network of kite and star facets that return direct white light to the eye, while the pavilion displays tiered facets that act to trap and recycle blue spectral content, and this interplay yields crisp scintillation coupled with stable, even color across the table, and facet junctions remain sharp under loupe inspection with minimal surface abrasion thanks to the excellent polish. From an optical standpoint, corundum, the species that sapphires belong to, has a refractive index that sits in the range of about one point seven six to one point seven seven, and a low dispersion which translates to modest fire compared with higher dispersion gems, and what the mixed brilliant strategy provides here is amplification of contrast and pinpoint scintillation rather than pronounced spectral flashes, and for a gem with intense blue saturation this approach preserves the depth of color while maintaining lively return of white light, and the polish quality increases specular reflection which contributes to the stone s perceived brilliance under varied lighting.

When compared with other blue gemstones in its category, this Ceylon sapphire demonstrates a reflective character that is distinct and technically advantageous for specific aesthetic aims, and compared with classic Kashmir sapphires which are often prized for their velvety diffusion of light and very strong saturation with softer internal contrast, this sapphire reads as slightly more lively and faceted in its light return, offering clearer facet definition and more pronounced scintillation. Compared with high quality Burmese sapphires which can show an intense, even color and strong internal glow, the present stone offers similar color intensity but with a typically brighter surface luster and more defined facet contrast due to the mixed brilliant proportions, and compared with Madagascar sapphires which can present a wide range of tones and clarity characteristics, this Ceylon example stands out for its combination of clean eye level clarity and consistent hue. Against other blue gems such as blue spinel, tanzanite, and blue topaz, the sapphire exhibits higher refractivity and a harder, more durable crystal lattice, and while spinel can show lively brilliance with high transparency, and tanzanite can display pronounced pleochroism and strong trichroic color shifts, and blue topaz can exhibit bright light return but less depth of color, this sapphire uniquely balances deep, saturated blue with resilient surface luster and stable face up appearance, and because corundum has low dispersion, the visual effect is primarily brilliant white sparkle punctuated by rich blue flashes, rather than rainbow fire.

From a practical and craftsmanship perspective, this stone s dimensions and proportions lend themselves to secure mounting options that take advantage of the mixed brilliant cut s optical advantages, and a medium to slightly elevated setting will allow light to enter the crown and interact with the pavilion tiers for maximum scintillation, and the excellent polish will provide a refined, jewel like sheen in both natural and artificial light, and the very slightly included clarity grade indicates inclusions are minimal and unlikely to compromise either durability or light performance for standard jewelry use. Heat treatment remains a widely accepted enhancement that stabilizes and intensifies blue coloration while preserving the crystal s structural integrity, and routine care involves avoiding exposure to sudden extreme temperatures and professional cleaning when setting work is performed, and for clients who prioritize provenance, optical performance, and long term wearability, this cushion mixed brilliant sapphire from Ceylon represents a technically superior option. The Natural Sapphire Company offers this gem with full disclosure of treatment and origin, and our lapidary and gemological teams can advise on mounting choices that preserve the ideal orientation for pleochroic balance, and when matched with a well engineered setting this sapphire will deliver enduring brilliance, saturated Ceylon blue, and the refined reflective qualities that knowledgeable buyers seek.
