3.90 Ct. Blue Star Sapphire from Ceylon (Sri Lanka)

You are invited to consider an exceptionally rare and refined gem from The Natural Sapphire Company, a translucent blue star sapphire that speaks to those who seek true exclusivity. This gem is GIA certified, weighing 3.90 carats, and fashioned into an elegant oval shape with measurements of 8.90 x 8.63 x 5.54 mm, a scale that balances presence with graceful wearability. Cut as a double cabochon, it reveals a precise and luminous asterism that captures light like a private star, an effect that is experienced rather than merely observed. With a clarity grade described as very slightly included when evaluated at eye level, the stone retains an intimate character that proves its natural origin and resists the uniformity of mass produced gems. The color intensity is faint, lending the piece an understated and sophisticated blue tone that will appeal to discerning collectors who prize subtlety over flash. The polish is excellent, and there has been no enhancement performed on this sapphire, a fact that further elevates its pedigree and desirability.

The provenance of this star sapphire traces back to Ceylon Sri Lanka, a source long celebrated for producing some of the finest and most coveted sapphires in the world. This origin contributes to the gem's unique fingerprint, a combination of crystal structure and rutile inclusions that generate the characteristic star with exceptional clarity against the translucent bodycolor. The double cabochon technique employed in shaping this stone is a specialist practice that enhances the depth and symmetry of the asterism, allowing a clean and centered star to traverse the surface as light moves. The faint blue hue, paired with this striking optical phenomenon, creates an objet d art that reads as both timeless and modern, suitable for bespoke creations intended for a private collection or for a statement piece that complements elevated daily wear. The GIA certification provides an independent assurance of the gem's unenhanced state and origin, a critical detail for anyone investing in a natural star sapphire.

Ownership of this singular piece places the buyer among a very small and distinguished group who can claim possession of an untouched Ceylon star sapphire with such precise dimensions and optical quality. Stones like this are seldom available, and they are even less often presented with full laboratory verification and a documented lack of enhancement. For those commissioning a setting, the stone's measurements and cabochon form suit both classic and contemporary designs, from a secure bezel that highlights the star to an open gallery mount that permits light to animate the asterism. Metals such as platinum and 18 karat yellow or rose gold each frame the faint blue in different ways, with platinum offering a cool, architectural presentation and warm gold tones bringing forward the softer aspects of the color. At The Natural Sapphire Company we can provide bespoke design consultations, CAD renderings, and artisan craftsmanship to ensure that this gem is set in a way that respects its natural beauty and maximizes its visual impact.
