134.88 Ct. Blue Sapphire Crystal from Ceylon (Sri Lanka)

A singular offering from The Natural Sapphire Company, this exceptional semi translucent blue sapphire weighs 134.88 carats, and measures 42.59 x 23.11 x 17.65 mm, various shape, with a rough crystal cut that celebrates the gem in a form that is both elemental and aristocratic. Origin Ceylon Sri Lanka, no enhancement, clarity graded very slightly included when evaluated at eye level, medium intense color intensity, and an excellent polish. The scale of this sapphire is immediately arresting, a statement gem that reads as both a collector piece and a wearable treasure for bespoke creations. There are very few sapphires of this size and unaltered provenance that present with such integrity, and ownership places you among a discrete circle of connoisseurs who value natural character, documented origin, and the rare combination of scale and clarity in an unheated Ceylon stone.

The optical personality of this sapphire is defined by its semi translucency and the way its medium intense blue breathes under light, with a top face that returns a soft, luminous sheen, and a body that hints at internal depth and movement. The rough crystal cut was chosen to retain the gemaceous presence of the original crystal, to emphasize the internal character rather than to create a conventional faceted flash. The excellent polish allows light to glide across the surface, producing a gentle, velveteen shimmer that is quintessentially Ceylon. Compared with highly faceted, fully transparent material, this stone offers a more contemplative dialog with light, where reflections are broader and more painterly, and where the play of light invites extended viewing. The eye level clarity grading of very slightly included confirms that the inclusions do not detract from the gem as worn, instead they authenticate the natural history of the sapphire and contribute to its individuality.

When set beside other gemstones in its category, the reflective qualities of this Ceylon sapphire stake out a distinct niche. Compared with Kashmir sapphires that are famed for a plush, pigeon blood blue depth and a soft, satiny luster, this stone reads brighter and livelier, with more open light return across its large table, while maintaining the depth that lends presence to serious gems. Against Burmese material that often carries greater saturation and density, the Ceylon character here is more aerial, with a clarity of hue that scatters light in a less concentrated manner, producing a more luminous face up appearance. Compared with blue spinel, which can display higher brilliance and a crystalline snap, this sapphire offers a subtler, more luxurious glow, favoring velvet over sparkle. Compared with tanzanite, which can show pronounced pleochroism and a chatoyant color shift, this sapphire is steadier, offering consistent blue across viewing angles with a steady vitreous luster. Compared with aquamarine and blue topaz, which rely on high transparency for their glassy flashes, this sapphire delivers a richer chromatic experience, and the rough crystal cut adds a tactile, almost primal interaction with light that those more conventionally faceted gems do not capture.

Owning this sapphire means securing a piece that is simultaneously rare, authentic, and profoundly individual, a gem that speaks to patience and refinement. The Natural Sapphire Company offers full documentation of origin and treatment, so the unenhanced nature of this Ceylon stone is assured, and the excellent polish confirms that the subtle surface finish will translate into compelling presence in any bespoke setting. For collectors who prize provenance and rarity, for jewelers seeking a showpiece that defies the ordinary scaled designs, and for patrons who wish to be part of an exclusive narrative around a natural treasure, this 134.88 carat sapphire is an invitation. We will assist with bespoke mounting options that respect the stone’s rough crystal sensibility, and we will provide guidance on settings that allow the stone to communicate its unique reflective language.
