0.81 Ct. Ruby from Tanzania

This transparent 0.81 carat cushion shape ruby measures 5.71 x 4.80 x 3.00 mm and presents a refined mixed brilliant cut, clarity graded as very slightly included when evaluated at eye level, vivid color intensity, and an excellent polish. The stone is untreated, with no enhancement, and originates from Tanzania, attributes that underscore its natural origin and appeal. The cushion profile and mixed brilliant faceting combine to deliver a lively play of light coupled with a concentrated red saturation, making the stone visually substantial for its weight. At 0.81 carat the proportions allow for a balanced presence on the hand or at the throat, while the depth and table relationships captured by the dimensions support consistent fire and return of red tone under varied lighting. The excellent polish ensures crisp facet junctions and controlled light leakage, and the very slightly included clarity grade indicates inclusions that do not detract from the gem when viewed without magnification, preserving both brilliance and resale integrity. These objective specifications are provided by The Natural Ruby Company to assist in design planning and certification.

This ruby is well suited for a wide range of custom jewelry settings, and its physical and optical properties support multiple mounting approaches. For a classic engagement ring, four or six prongs allow maximum exposure of the pavilion to light, enhancing brilliance, while a low profile bezel can provide a contemporary, secure look without diminishing color depth. A halo of small diamonds or white sapphires will create contrast and perceived size, whereas a pavé band emphasizes continuity for a refined statement piece. As a pendant, the cushion shape sits elegantly in a simple bezel or in a partial crown mounting to permit light from the back, and the 5.71 x 4.80 mm footprint works well for both solitaire and three stone compositions. For earrings, matched pairs can be fashioned into studs with minimal metal to showcase color, or into drop settings with complementary accent stones for movement and sparkle. The absence of enhancement and the gem origin from Tanzania make this ruby particularly attractive to clients seeking natural provenance, and The Natural Ruby Company can advise on metal choices, prong design, and setting height to optimize durability and light performance. Custom design services can accommodate ring sizes, pendant lengths, and complementary gem selections, ensuring the finished piece aligns with technical requirements and aesthetic intentions.
