0.99 Ct. Bi Color / Parti Sapphire from Ceylon (Sri Lanka)

At The Natural Sapphire Company we present a truly exceptional find, a transparent 0.99 carat cushion shape bi color parti sapphire that embodies rarity and refined taste. This gem measures 5.97 x 5.15 x 3.46 mm, and is faceted with a mixed brilliant cut that balances lively brilliance with classic depth. Its intense color intensity and excellent polish allow each facet to sing, while the clarity grade of slightly included evaluated at eye level speaks to its natural origin and character. Heat treated to enhance color stability and uniformity, this sapphire retains a distinctly natural voice, one that is immediately recognizable to those who appreciate genuine rarity. We offer this single stone as a bespoke opportunity for the collector who seeks something unique, an opportunity to own a one of a kind parti sapphire that shifts and breathes with every turn, a jewel that will not be easily replicated.

Durability is a cornerstone of why sapphires are favored for daily wear, and this 0.99 carat Ceylon sapphire is no exception. Sapphires rate nine on the Mohs hardness scale, second only to diamond, which gives them outstanding resistance to scratches and surface wear during the rhythms of everyday life. The mixed brilliant cut contributes to structural integrity by distributing forces across an intelligent facet pattern, and the excellent polish reduces microabrasion by presenting smooth reflective planes. The heat treatment applied to this stone is a stable enhancement commonly used in fine sapphires, designed to improve color and clarity without compromising toughness. For daily jewelry such as engagement rings, signet rings, pendants, and daily wear earrings, we recommend settings that offer security and protection, such as low bezel mounts or refined prong settings paired with protective galleries. Choosing robust metals like platinum or heavy gauge 18k gold will further ensure that this parti sapphire remains a steadfast heirloom for years to come.

What makes this cushion shape bi color parti sapphire particularly intoxicating is the living interplay of hue and tone within a compact, elegant profile. The parti characteristic reveals distinct patches and flashes of teal blue, forest green, and warm golden yellow, each tone appearing and retreating as light and perspective change. The mixed brilliant cut amplifies that play by creating a lattice of scintillation and color, allowing the intense color intensity to manifest as both saturation and contrast. Face up, the proportions lend a lively presence that reads larger than its weight would suggest, while the 3.46 mm depth preserves light return and depth with no sacrifice to brilliance. The slightly included clarity grade is typical of natural sapphires and often adds to the gem's personality, a fingerprint of its formation deep within Ceylon terrain. The excellent polish ensures that every facet reflects with crisp clarity, so that under natural daylight or warm indoor light the stone alternately glows with oceanic blue green and warms with unexpected amber highlights.
