Product description

When you are searching for a stone that will end the hunt for a singular engagement ring focal point or become the centerpiece of a carefully curated collection, this 2.36 carat oval black star sapphire answers that call. It is an opaque gem cut as a cabochon to reveal an intense star effect, presenting a deep, dramatic presence that feels both timeless and modern. With dimensions of 8.98 x 6.87 x 3.45 mm it sits comfortably on a finger or in a pendant, offering a bold, wearable size without overpowering a design. The cabochon cutting style and excellent polish work together to emphasize the silky smooth dome and to produce a sharp, centered star that shifts with the light, so that the moment you present this gem to a client or place it into a bespoke mounting they immediately sense that their search has been successful. The Natural Sapphire Company sources and presents this gem with full transparency, and the stone comes to you in its natural state, with no enhancement, straight from Ceylon Sri Lanka.

From every angle this black star sapphire reveals the art of fine lapidary work, and its flawless quality enhances its beauty in ways that become obvious with a single turn beneath a lamp. The cabochon dome is polished to a mirror like finish which allows highlights to glide across the surface while preserving the diffuse internal glow that makes star sapphires so mesmerizing. The dark color intensity gives the star a dramatic contrast, so the ray like asterism appears precise and bright, rather than washed out. Because the stone is opaque the light interacts with the internal needle like inclusions in a way that creates a steady, centered star rather than a transient flash, and the symmetry of the oval shape keeps that star perfectly aligned whether the gem is set horizontally or vertically. The excellent polish enhances the tactile experience as well, inviting touch and close inspection while ensuring that faceted settings and prongs seat cleanly without distracting gaps or uneven edges.

Collectors, designers, and couples will appreciate the rare combination of natural origin and untouched character that this gem offers, origin Ceylon Sri Lanka being a hallmark of historical and gemological significance. It is not common to find a star sapphire of this size and clarity that has not been heat treated or otherwise enhanced, so the stone represents a meaningful investment for someone seeking authenticity and provenance. The robust hardness that sapphires are known for makes it suitable for everyday wear, and the oval cabochon profile lends itself to a wide range of settings, from a classic bezel that protects the edges and showcases the star to an open back pendant that allows a hint of light to animate the asterism. The 8.98 x 6.87 x 3.45 mm proportions make custom design straightforward, and the 2.36 carat weight gives the piece a presence that reads as substantial on the hand while still allowing for elegant, wearable proportions.

When you choose this stone from The Natural Sapphire Company you are not only selecting a visually arresting black star sapphire, you are selecting a gem that resolves the search for rarity, quality, and integrity. We understand that customers who come to us seeking the perfect stone are often balancing emotional significance with practical considerations, and this gem delivers on both counts, offering a mesmerizing star, uncompromised natural origin, and a polish and cabochon shape that enhance its beauty from every vantage point. Whether you are designing an unconventional engagement ring that will be talked about for years, assembling a collection that values provenance and character, or crafting a one of a kind pendant, this Ceylon black star sapphire is the stone that brings focus, dignity, and wonder to the finished piece. Allow us to assist with mounting suggestions and secure shipping so that your selection arrives ready to make the statement you intend, a decision that will feel as right the day you commission the setting as it will a decade from now.
