1.07 Ct. Blue Sapphire from Ceylon (Sri Lanka)

One beautiful transparent 1.07 carat cushion shape blue sapphire is presented here by The Natural Sapphire Company, offering a compact and vivid example of classic Ceylon material. The stone measures 5.70 x 4.83 x 4.09 millimeters, and it is cut as a mixed brilliant cushion to balance table facet brightness with pavilion scintillation. The color intensity is described as intense, with a saturated medium to deep blue tone that reads as lively and pure in both direct and diffused lighting. Clarity is graded as very slightly included, evaluated at eye level, and the gem has an excellent polish that maximizes surface reflectivity and the crispness of facet junctions. This sapphire has been enhanced by a standard heat treatment, a stable and widely accepted process that enhances color uniformity and overall appearance without compromising durability.

For the educated buyer interested in grading implications, a 1.07 carat weight in a cushion mixed brilliant cut yields notable face up spread for its dimensions, making it appear lively on the finger while remaining comfortable in everyday settings. The mixed brilliant cut combines a larger table with multiple small facets in the pavilion, creating a pleasing balance between broad flash and small scintillation points. An excellent polish indicates that cutters have achieved smooth facet planes and crisp facet edges, which in turn improves light return and perceived transparency. The clarity designation very slightly included evaluated at eye level means that any natural inclusions are minor and do not materially disturb the gem when observed without magnification, providing the visual cleanliness most buyers prefer while retaining natural origin. Heat treatment in sapphires is endemic and accepted throughout the trade, and when disclosed it should be considered a standard enhancement that improves color without reducing longevity. Origin from Ceylon, Sri Lanka, adds a provenance premium for many collectors and designers, as Ceylon sapphires are prized for their vibrant, often slightly velvety blue that differs from the deeper cornflower tones of other sources.

This sapphire is exceptionally versatile, well suited to both casual and formal settings, and it adapts gracefully to a range of mounting styles. In a solitaire ring it reads as refined and confident, offering a focused point of color that works with everyday attire and elevates formal evening wear. In a halo setting it gains presence and a classic vintage character, while a three stone design pairs well with tapered or trillion cut side stones for a modern statement. The intense blue translates beautifully to different metals, pairing cleanly with platinum for a cool and contemporary look, yellow gold for a warm and traditional contrast, or rose gold for a softer, fashionable tone. The stone is small enough to be comfortable in bezel settings that protect the girdle and pavilion for daily wear, and it is large enough to anchor delicate pendants and stud earrings while still projecting the saturated Ceylon blue that is immediately readable at conversational distance.

For a buyer who values factual information and long term worth, this sapphire represents a nuanced balance of desirable attributes. Color intensity, origin, cut quality, and eye level clarity are the primary drivers of value in a sapphire of this size, and each of those factors is favorable here. The Natural Sapphire Company provides transparent information about enhancement and origin, and our gem specialists can advise on certification options to match a client’s needs, whether that involves an internal report or an independent laboratory analysis. Sapphires rank nine on the Mohs scale, which makes them well suited to daily wear when set appropriately and cared for with routine cleaning using warm soapy water and a soft brush. For collectors considering future liquidity, Ceylon sapphires with vivid color and clean presentation remain consistently sought after, especially when accompanied by clear documentation of treatment and origin.

If you would like additional photographic angles, bespoke setting proposals, or independent grading, The Natural Sapphire Company is happy to assist. We can provide guidance on optimal metal choices and prong designs that protect the pavilion and emphasize the stone’s intense blue, and we can discuss complementary diamond weights for halo and side stone arrangements that maximize perceived size without overwhelming the sapphire’s character.
