1.55 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 1.55 carat oval blue sapphire measures 7.43 x 5.64 x 4.41 mm, and its proportions have been optimized with a mixed brilliant cut to maximize face up brilliance and overall light performance. The gem displays intense color intensity, a highly desirable saturation for Ceylon stones, and an excellent polish that produces strong luster and crisp facet reflections. Clarity is described as very slightly included, evaluated at eye level, which means the stone presents very few internal features to the naked eye, preserving transparency and allowing the intense blue to read clearly across the table. The mixed brilliant cut enhances scintillation while the oval shape provides an elegant footprint for a ring or pendant, making the most of the 1.55 carat weight in both appearance and wearability.

The weight of 1.55 carats is a significant attribute and directly contributes to the sapphire's value and rarity. Sapphires above the 1 carat threshold, and particularly those that move past 1.5 carats, enter a less common size category where per carat prices typically increase, especially for stones with strong color and eye level clarity. This specimen, originating from Ceylon Sri Lanka, benefits from provenance that is historically sought after for its vivid cornflower to violet blue tones, and when combined with the intense color and very slight inclusions, the 1.55 carat weight commands a premium relative to smaller, more commonly encountered sizes. The stone has been heat treated, a standard and stable enhancement in the industry that improves color and clarity in a permanent way when performed correctly, and this treatment is disclosed in full to ensure transparent purchasing. At The Natural Sapphire Company we emphasize accurate grading and ethical sourcing, and this particular sapphire represents a balanced combination of weight, color, clarity, and cut, offering an excellent option for buyers seeking a meaningful center stone that is both visually impressive and comparatively rare for its size.
