17.67 Ct. Bi Color / Parti Rough Sapphire Crystal from Ceylon (Sri Lanka)

This translucent 17.67 carat bi color or parti sapphire presents as a rare specimen, a rough shape crystal that captures light with a soft internal glow. The crystal cutting style is a rough crystal cut, with an excellent polish that highlights the stone surface while preserving its natural character. With dimensions of 21.44 by 10.73 by 9.55 mm, this piece reads as a statement gem, unobtrusive in form yet undeniable in presence. Its medium color intensity and very slightly included clarity, evaluated at eye level, ensure that its natural beauty is both authentic and wearable. Originating from Ceylon Sri Lanka and carrying no enhancement, this sapphire arrives to you exactly as the earth formed it, a provenance that collectors and connoisseurs value deeply. For those who appreciate complementary contrasts, we note White Opal as an opal type that pairs beautifully with this parti sapphire, offering a soft luminescent foil to the sapphire tones.

As a member of the corundum family, this sapphire combines extraordinary resilience with inherent charm, making it ideal for daily wear in rings, pendants, or custom pieces. Its hardness, second only to diamond among common gem materials, resists scratches and preserves edges and polish through years of regular use, while the very slightly included clarity speaks to natural formation rather than treatment, reducing susceptibility to surface alterations. The excellent polish enhances wearability by minimizing snag points, and the rough crystal aesthetic lends itself to bespoke settings that protect the stone without concealing its unique form. When set by skilled jewelers, this sapphire adapts to everyday life, resisting knocks and daily exposure, yet maintaining the soft translucency that gives it its distinctive look.

This offering from The Natural Sapphire Company is presented as a limited opportunity, a single 17.67 carat rough bi color sapphire that will not be replicated. Each detail from the unenhanced origin in Ceylon Sri Lanka to the crystal cut and untouched surface creates a bespoke story for its owner. Owning this gem places you among an exclusive group who recognize and cherish natural rarity, a collector who prefers authenticity over mass produced perfection. If you desire a piece that feels rare in hand and rare by provenance, this sapphire is ready for a custom commission, and our team will guide you through design options that might include a companion White Opal for a truly singular creation.
