2.11 Ct. Greenish Brown Star Sapphire from Ceylon (Sri Lanka)

This exquisite translucent star sapphire from Ceylon presents a rare and compelling combination of color, optical phenomenon, and fine craftsmanship. Weighing 2.11 carats, the oval form measures 7.66 x 6.84 x 3.52 mm, and it has been expertly fashioned into a classic cabochon to maximize the asterism that makes star sapphires so desirable. The hue is best described as greenish brown with medium color intensity, a tone that reads as both earthy and sophisticated depending on the lighting. The cabochon cut is tailored to the orientation of the internal needle like inclusions, creating a clean and focused star that appears to glide across the dome as the gem moves. The Natural Sapphire Company offers this piece as an untreated, natural specimen from Sri Lanka, a country long celebrated for producing some of the world s most collectible and well balanced corundums.

From a gemological perspective the stone is graded as slightly included at eye level, and it carries an excellent polish. Slight inclusions in star sapphires are not only common, they are integral to the very effect that defines the gem. The six ray asterism is produced by oriented rutile needles, known as silk, which scatter light to form the characteristic star. In this example the silk distribution is sufficient to yield a distinct star against a translucent body, while not overly dense so as to obscure the overall color and internal glow. Medium color intensity means the saturation is noticeable without being overpowering, which allows the star to remain the focal point. The excellent polish enhances light return across the dome so that the star appears crisp and well defined. Importantly there has been no enhancement to alter color or clarity, which preserves both the integrity and market value of the stone.

To the educated buyer the combination of natural asterism, Ceylon origin, absence of treatment, and thoughtful cutting delivers a compelling package. Ceylon sapphires are distinguished by a balance of tone and lightness that flatters both contemporary and classic jewelry designs, and an untreated star of this size at 2.11 carats occupies a niche between wearable daily rings and collector grade museum pieces. The oval dimensions provide an elegant silhouette that adapts well to bezel or halo settings, with the cabochon height at 3.52 mm offering enough dome to display the star prominently. Slight inclusions, when evaluated honestly, affirm the gem s natural formation and do not compromise structural integrity given corundum s hardness of 9 on the Mohs scale. For those who value provenance and natural character, this greenish brown star sapphire communicates personal power and distinction through its rich, bold color and luminous star, making it suitable as a signature ring, a bespoke pendant, or a highlighted stone in a bespoke cuff.

When you choose this star sapphire from The Natural Sapphire Company you receive more than an attractive gemstone, you receive full support in understanding and preserving your purchase. We provide detailed documentation of origin and treatment status, and we can supply additional images and video under varied lighting to demonstrate the star movement and color range. For setting recommendations a secure bezel will protect the dome and show the star to best advantage, while a custom mount can position the stone so the star always aligns with the table as worn. Routine care is straightforward, warm soapy water and a soft brush are sufficient, and no ultrasonic or steam cleaning is advised for stones with oriented silk to avoid stress on inclusions. For collectors and connoisseurs who appreciate the nuanced interplay of color, phenomenon, and natural authenticity, this Ceylon star sapphire represents a discrete yet powerful emblem of distinction, backed by The Natural Sapphire Company s commitment to ethical sourcing, accurate grading, and personalized service.
