0.87 Ct. Ruby from Thailand

This transparent cushion shape ruby weighs 0.87 carat, and measures 6.10 x 5.32 x 2.78 mm, presenting a balanced face up profile and a pleasing depth for wearable jewelry. The stone is faceted with a mixed brilliant cut that combines step and brilliant faceting to maximize both color saturation and scintillation. The color is described as vivid in intensity, delivering a pure and unambiguous red that reads clearly even under varied lighting. Clarity is graded as very slightly included, evaluated at eye level, indicating minor natural features that do not detract from the overall transparency or visual appeal. The polish has been assessed as excellent, providing clean facet surfaces that support strong light return and an attractive, consistent luster. This ruby has been heat treated, a common and stable enhancement technique used to optimize color and clarity, and its origin is Thailand, a source known for producing well colored rubies with warm red tones.

The mixed brilliant cutting style on this cushion form is designed to balance internal color distribution with surface brightness. Faceting patterns are arranged to allow light to enter and reflect from both the crown and pavilion, enhancing the gem s fire while permitting the vivid red to remain the dominant visual attribute. The moderate proportions, with a table and depth relationship appropriate for a 0.87 carat weight, result in a face up appearance that reads larger than the weight alone might suggest when set in open, well proportioned settings. Transparency contributes to the stone s presence, allowing the red hue to be seen through the gem rather than being confined to surface flashes alone. The very slightly included clarity grade denotes inclusions that are confined and stable, they do not compromise durability, and under standard examination at eye level the stone appears clean and lively. Excellent polish ensures crisp facet junctions and minimal surface disturbance, supporting both precise light performance and ease of setting.

In jewelry applications this ruby s vivid color will make a clear visual statement, contrasting or harmonizing with surrounding materials depending on design choices. Set in yellow or rose gold, the red will read warmer and more saturated, while settings in white metals such as platinum or white gold will emphasize contrast and a contemporary aesthetic. Prong settings and semi mounted designs that allow light to enter from multiple angles will best exploit the faceting regime and transparency, while bezel settings will offer greater protection and a streamlined silhouette at the expense of some lateral light entry. When paired with accent gemstones, a halo of colorless diamonds will increase apparent brightness and focus attention on the central red, whereas colored accents can be used to create tonal harmony or deliberate contrast. The dimensions and weight make this ruby suitable for a range of applications, including ring centers, pendant focal points, and single stone earrings, and the cushion outline brings a classic yet versatile profile that works with both traditional and modern designs.
