0.89 Ct. Ruby from Thailand

This GIA certified ruby represents a refined example of classic gemstone quality, presented by The Natural Ruby Company as an ideal addition to a high end collection. The stone weighs 0.89 carat and is fashioned into an oval shape with precise dimensions of 6.23 x 4.77 x 3.10 mm. The cutting style is a mixed brilliant cut, combining pavilion facets that enhance light return with a faceted crown that preserves color saturation. The gem is transparent with an intense color intensity, exhibiting a vivid red that reads with both depth and clarity to the naked eye. The GIA certification provides an independent verification of the ruby attributes, including weight, shape, dimensions, clarity description, and the documented enhancement of heat treatment. Origin is recorded as Thailand, a source known for producing rubies with rich hues and stable material characteristics. The excellent polish and well executed proportions make this ruby suitable for display in a curated cabinet of important stones, or as the centerpiece in a bespoke jewelry commission intended to reflect refined taste and technical appreciation.

The color of this ruby is its most compelling attribute, described by laboratory grading as intense and consistently distributed across the table and pavilion facets. Under controlled lighting the stone demonstrates a warm, saturated red with minimal secondary tones, producing an overall visual presence that reads as true red rather than overly purple or overly orange. Transparency is high for a natural ruby of this weight, allowing internal light paths to interact with facet geometry and generate balanced scintillation. Clarity is graded as slightly included when evaluated at eye level, which indicates small natural features that do not detract from overall appearance when mounted or viewed at a normal arm length. These minor inclusions are typical for natural ruby and serve as internal fingerprints that confirm natural origin when combined with gemological testing. The mixed brilliant cut magnifies the gemological harmony between color and brilliance, and the excellent polish enhances facet definition so that light disperses cleanly rather than appearing dull or clouded.

The oval outline offers both aesthetic versatility and efficient yield from rough material, translating into measured proportions that optimize face up area relative to weight. The length to width ratio presents a balanced silhouette appropriate for rings, pendants, or earrings, and the depth of 3.10 mm supports secure bezel or prong settings without sacrificing optic performance. The mixed brilliant cut introduces a combination of step and brilliant facet arrangements, which encourages a lively interplay of flashes and a stable color tone across viewing angles. Symmetry and facet alignment are consistent with a stone prepared for high end settings, and the excellent polish indicates skilled lapidary work. The GIA report accompanying this ruby documents the weight, measurements, cut style, clarity description, color intensity, and the presence of heat treatment enhancement. This independent documentation enhances provenance and supports resale and insurance appraisal processes, providing objective data for collectors and professional jewelers.

Origin and enhancement are important considerations for a high end collection, and this ruby carries the provenance of Thailand with heat treatment recorded as the applied enhancement. Heat treatment is the most common and accepted method for improving color and clarity in rubies, and when disclosed and documented by a reputable laboratory it preserves the integrity and value of the material. From a care perspective, standard precautions for corundum apply, including avoiding prolonged exposure to high heat or harsh chemicals, and recommending routine cleaning with warm soapy water and a soft brush. For collectors who intend to mount the stone in a frequently worn piece, professional setting and secure mounting are advised to protect the girdle and pavilion. The Natural Ruby Company stands behind the documentation and condition of this gem, and recommends independent appraisal for insurance and valuation. Overall, this 0.89 carat Thai ruby, with its intense color, slightly included clarity at eye level, mixed brilliant cut, and excellent polish, represents a sophisticated selection for a discerning collection, offering both aesthetic presence and verifiable gemological credentials.
