0.90 Ct. Blue Sapphire from Ceylon (Sri Lanka)

One transparent 0.90 carat pear shape blue sapphire, dimensions 7.83 x 5.00 x 3.06 mm, mixed brilliant cut, clarity grade very slightly included evaluated at eye level, intense color intensity, excellent polish, no enhancement, origin Ceylon Sri Lanka, presented by The Natural Sapphire Company. The stone is precisely weighed and measured to provide accurate information for design and appraisal. The pear outline combines a sharp but well formed point with a gently rounded base, offering a balance between elegance and wearability. The mixed brilliant facet arrangement contributes to lively scintillation and controlled light return, while the excellent polish ensures crisp facet junctions and minimal surface disturbance. The absence of any enhancement establishes this sapphire as a natural, untreated gem, retaining its original crystal structure and color saturation as found in the Ceylon deposits.

The color of this sapphire is identified as an intense blue with good saturation and even distribution across the pavilion and crown. Ceylon origin is associated with a range of lively blue tones, and this particular specimen displays a vivid face up appearance that reads as pure blue under standard lighting. The mixed brilliant cut enhances contrast and brilliance, producing flashes of light and depth that accentuate the stone color without overpowering it. The length to width ratio is approximately 1.57, a proportion that suits classic pear shape settings and provides a refined elongation on the finger. The depth of 3.06 mm supports stable light performance without creating excessive windowing or a dark face up. The excellent polish maximizes the visual clarity and ensures the surface condition will not interfere with typical jewelry fabrication processes.

Clarity is graded very slightly included evaluated at eye level, indicating the presence of minor internal characteristics that are small and not disruptive to the overall transparency. Under normal viewing, the stone reads as clean and transparent, with inclusions that do not significantly affect brilliance or durability. The untreated status, recorded as no enhancement, is particularly significant for collectors and connoisseurs who seek natural stones in their original state. Origin reporting to Ceylon Sri Lanka provides provenance context, reflecting geological conditions that often yield stones with lively blue tones and attractive clarity. The combination of intense color and minimal internal characteristics makes this sapphire a strong candidate for a centerpiece gem in fine jewelry, where natural origin and lack of treatment are valued attributes.

In terms of durability, sapphire is a corundum mineral with a Mohs hardness of 9, making it one of the hardest gem materials available. On the Mohs scale it is second only to diamond which rates 10, and it is substantially harder than many other common gemstones such as topaz and quartz. This high hardness translates to excellent resistance to scratches from everyday contact, which contributes to longevity when set in rings, pendants, and other frequently worn pieces. Hardness does not eliminate the risk of chipping or cleavage under severe impact, especially at points and girdles, so protective settings that guard the pointed end of a pear shape are recommended for maximum serviceability. The stone’s excellent polish and stable clarity further reduce surface wear, but standard care practices for fine gems remain advisable to preserve optical qualities over time.

Practical applications for this 0.90 carat pear shape sapphire include use as a center stone in an engagement ring, a solitary pendant, or as a focal element in bespoke designs that require a refined elongated silhouette. The dimensions 7.83 x 5.00 x 3.06 mm allow for a range of classic and contemporary mounting styles, and the intense blue color provides strong visual presence for its weight. The Natural Sapphire Company provides detailed measurement and condition reporting to assist with design decisions and certification. For setting considerations, protecting the pointed tip with a bezel or prong design to minimize exposure to knocks will help maintain the structural integrity of the stone. The untreated Ceylon provenance, combined with the mixed brilliant cut and excellent polish, offers a balanced profile of aesthetic quality and practical durability for long term wear.
