0.85 Ct. Purplish Blue Sapphire from Ceylon (Sri Lanka)

This purplish blue sapphire offered by The Natural Sapphire Company is a transparent, round faceted gem weighing 0.85 carat, with precise dimensions of 5.90 x 5.95 x 3.11 mm. The mixed brilliant cut has been executed to balance both color saturation and light return, and the excellent polish enhances the crispness of each facet. Color is intense, presenting the sought after violet to blue shift that Ceylon sapphires are renowned for, and clarity has been graded as very slightly included when evaluated at eye level, indicating only minor internal features that do not detract from the gem face up. This sapphire has been heat treated, a standard and stable enhancement that improves both clarity and color without compromising structural integrity, and its origin from Ceylon Sri Lanka adds provenance that educated buyers recognize and value due to the island s long history of producing richly colored, gem quality corundum.

Weight is a primary driver of value in sapphires, and 0.85 carat occupies an attractive position on the pricing curve. While the visual face up size corresponds to the five point nine millimeter range, which reads as a substantial presence in many ring and pendant settings, the sub one carat weight often yields a more favorable price per carat compared to stones that cross the one carat threshold. For the discerning buyer who understands carat weight economics, this means acquiring a gem that appears nearly as large as a one carat example, while avoiding the steep premium that typically attaches to that round figure. In addition to pure market mechanics, the rarity profile of a deeply saturated purplish blue sapphire at this weight is notable, because many stones in this size bracket are either paler or more heavily included. The combination of intense color, eye level very slight inclusions, and a well executed mixed brilliant cut produces a gem that maximizes face up color and brilliance, thereby amplifying perceived size and presence beyond what the carat number alone might suggest.

From a connoisseur s perspective the technical details support both aesthetic enjoyment and long term value. The mixed brilliant cut concentrates light in the pavilion area to produce scintillation and depth of hue, while the carefully maintained proportions at three point one one millimeters in depth ensure that the stone is not overly dark or windowed. The very slightly included clarity grade means the stone will appear clean to unaided vision under normal viewing distances, yet retains the natural fingerprint that many collectors prefer over fully apparent synthetic or heavily treated material. Heat treatment is disclosed openly, and in the market it is considered a routine, stable enhancement that enhances desirability without the complications of fracture filling or dyeing. Origin from Sri Lanka imparts a historical and gemological context that is meaningful to educated buyers, because Ceylon sapphires are often prized for their lively blue violet tones and balanced saturation. For practical use the corundum hardness makes this sapphire ideal for daily wear, whether set in a solitaire ring, a three stone design, or as a colored accent in a bespoke piece. At 0.85 carat this stone represents a strategic purchase, offering near one carat visual impact, efficient value relative to per carat pricing increments, and the authentic attributes that collectors and sophisticated buyers seek. The Natural Sapphire Company stands behind clear disclosure of cut, clarity, treatment, and origin, and this purplish blue 0.85 carat round sapphire exemplifies the blend of beauty, rarity, and market sense that informed purchasers appreciate.
