0.69 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 0.69 carat oval blue sapphire presents as a transparent, neatly proportioned gemstone, with precise dimensions of 6.06 x 4.48 x 3.13 mm, making it an ideal candidate for refined jewelry and focused collection pieces. The stone has been fashioned in a mixed brilliant cut, a style that combines a faceted crown with a cut pavilion to optimize light return and color saturation. Clarity has been evaluated at eye level as very slightly included, indicating minimal internal characteristics that do not materially detract from its visual appeal or light performance. The color is described as intense, a depth of blue that is immediately perceptible and consistent across the table and crown facets, and the polish has been assessed as excellent, delivering crisp facet junctions and a smooth, reflective surface. Importantly, this sapphire carries no enhancement, a factor that materially affects both its rarity and long term appearance, and its origin is recorded as Ceylon, Sri Lanka, a source historically associated with fine blue sapphire material.

From the perspective of connoisseurship and technical attributes, this sapphire offers a balance between optical performance and practical wearability that suits a high-end collection. The mixed brilliant cut amplifies scintillation while maintaining even color distribution, and the oval outline contributes to a perception of larger face up size relative to weight, which is beneficial for collectors who prioritize visual impact. The very slightly included clarity grade means the stone reads clean to the unaided eye in most viewing conditions, while the transparent body permits accurate assessment of hue and saturation. Sapphires are notable for their durability, possessing a Mohs hardness of nine, and this specimen is sufficiently robust for daily wear when set in secure mounting styles. Proportions and table size support versatile setting options, including solitary ring designs, pendant mounts that highlight the oval silhouette, or as a matched accent within a more intricate composition, and the intense blue color responds well to complementary metals such as platinum, white gold, and yellow gold depending on the desired contrast.

The provenance of this sapphire from Ceylon, Sri Lanka, together with the untreated nature of the stone, situates it among material that is favored by discerning collectors and specialists. The Natural Sapphire Company sources gemstones with documented origins and provides transparent reporting on enhancement status, dimensions, cut style, and gemological observations to support informed acquisition decisions. Untreated sapphires of notable color intensity from established origins are comparatively uncommon, and their stability and natural character contribute to both aesthetic and long term value considerations. For care, routine cleaning with warm soapy water and a soft brush will maintain the stone’s polish and luster, avoiding extreme thermal shocks and harsh chemicals will preserve its integrity, and professional inspection of the setting is recommended periodically to ensure secure mounting during regular wear. Presented with concise technical information and provenance, this 0.69 carat Ceylon blue sapphire is a fitting addition to a high end gemstone collection, offering natural color, sound physical attributes, and the documented authenticity that collectors seek.
