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

One beautiful transparent 0.87 carat radiant shape bi color parti sapphire is offered by The Natural Sapphire Company, a gem that brings a rare and lively personality to any jewelry design. The stone measures 6.53 x 4.94 x 2.92 mm, and is faceted in a radiant cut that marries the brilliance of a brilliant style face with the elegant symmetry of a step style pavilion. This parti sapphire shows a thoughtful balance of blue tones with lighter, near colorless areas that create an internal landscape of shifting hues as it moves, giving the gem a unique visual depth. The clarity is graded very slightly included when evaluated at eye level, which means the stone reads as essentially eye clean, while the excellent polish ensures maximum light return and crisp facet delineation. Origin matters with colored gemstones, and this sapphire comes from Ceylon Sri Lanka, a classic source known for lively, velvety tones and high quality rough that cutters can shape into gems with superb optical character. The gem has been heat treated, a standard and stable enhancement that is widely accepted in the trade for improving color and clarity, and the result is a durable, attractive stone that will hold its appeal for years.

When comparing hardness on the Mohs scale to ensure durability, sapphire scores a nine, which places it just below diamond, the hardest natural material at ten. That nine rating means this Ceylon sapphire resists scratching from virtually all common materials encountered in daily wear, and it stands well above many other popular gemstones. For example, topaz is an eight on the Mohs scale, quartz including amethyst and citrine is a seven, and emerald which is a type of beryl typically ranges around seven and a half to eight. What that means in practical terms is that this sapphire will show far fewer surface scratches than gemstones that rate lower, and it will retain its polish and crisp facet edges through routine activities that can abrade softer gems. The corundum family to which sapphire belongs is renowned for its toughness in addition to surface hardness, so chips and fractures are less likely when the gem is set and cared for properly. For customers seeking a piece that combines resilience with beauty, this radiant cut bi color sapphire is a superior choice for rings and bracelets that experience frequent contact, and it compares favorably to other stones commonly used in engagement and statement jewelry which may require more careful handling.

In a market full of options, this 0.87 carat Ceylon parti sapphire stands out for a combination of attributes that signal quality and long term value. Compared to lower grade or heavily included sapphires, this stone shows an eye clean appearance and an excellent polish that translates directly into a more vivid performance on the finger. When stacked against lab grown or imitation stones, the natural origin and trace mineral fingerprint of this gem offer collectible interest and potential appreciation, while still delivering the modern benefits of a heat treated enhancement that is stable and permanent. The radiant cut is particularly advantageous, because its mixed facet architecture enhances color distribution and sparkle more effectively than some step cuts or cabochon shapes, making the parti color play lively without losing the overall body color. From a value perspective, stones with this combination of medium color intensity, clean appearance, and classic Ceylon provenance represent a smart purchase for someone who wants both daily wearability and distinctiveness. At The Natural Sapphire Company we provide full transparency on origin and treatment, and we advise protective mounting options such as secure prong work or a partial bezel to safeguard the girdle while preserving light performance. This sapphire is ready to become the focal point of a custom piece or an heirloom design, combining the durability of a Mohs nine hardness, the visual interest of a bi color parti character, and the assurance of careful sourcing and cutting that we stand behind.
