0.78 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent blue sapphire weighs 0.78 carat, an especially meaningful weight for buyers who understand how carat influences rarity and value. Its oval outline measures 7.03 by 4.04 by 2.67 millimeters, providing a graceful length to width ratio that enhances wearability while maximizing the visual surface area. The gem has a mixed brilliant cut that combines step facets on the pavilion with a brilliant style crown, producing lively scintillation and a balanced mix of flash and overall brightness. The excellent polish further amplifies light return and surface luster, so the stone appears lively and clean when set. Clarity has been evaluated at eye level as very very slightly included, which means any natural inclusions are minute and generally not visible without magnification, allowing the sapphire to present excellent transparency and a clear body color. The color intensity is described as light, a classic and highly sought after hue from Ceylon, Sri Lanka, where this sapphire originates. Importantly, there has been no enhancement, no heat or other treatment of any kind, a factor that meaningfully increases collectibility and long term value.

Weight significantly affects both market value and rarity for natural sapphires, and 0.78 carat sits at an attractive point for connoisseurs and jewelry designers alike. Sapphires are priced on a per carat basis that tends to rise nonlinearly, so stones approaching whole carat weights command proportionally higher premiums than their incremental weight might suggest. At 0.78 carat this sapphire benefits from the economies of proportion, offering a size that reads larger than its weight might imply due to the oval shape and well executed table, while remaining within an accessible range for fine settings. The depth of the stone measures 2.67 millimeters, which equates to about 48 percent depth relative to the average of the length and width, a proportion that supports good light performance without appearing shallow. For the educated buyer, the absence of enhancement is particularly relevant, because untreated Ceylon sapphires of this clarity and cut are much less common than treated material. The provenance from Sri Lanka adds contextual value, as Ceylon sapphires are historically prized for their delicate, luminous blues and for the variety of tones that are difficult to replicate elsewhere, making an untreated example both aesthetically and materially desirable.

When considering use in finished jewelry, the combination of 0.78 carat weight, the oval silhouette, and the mixed brilliant faceting makes this stone exceptionally versatile. It will sit elegantly as a solitary center stone in a refined engagement setting or be paired with side stones where its light color and clarity will harmonize with diamonds or complementary gems. The modest weight also helps preserve daily wearability and allows for secure bezel or prong settings that protect the girdle without hiding the profile. For buyers who prioritize investment quality, the intersection of natural origin, untreated status, very very slightly included clarity at eye level, and excellent polish offers both visual beauty and sound long term appeal.
