3.52 Ct. Ruby from Mozambique

This transparent 3.52 carat cushion shaped ruby, measuring 8.98 x 7.91 x 5.16 mm, exemplifies the attributes an educated buyer seeks, combining substantial face up size with careful cutting and finishing. The gem is cut in a mixed brilliant style, a choice that balances the pavilion facets for optimal light return with crown facets that showcase color, yielding a lively appearance without sacrificing weight retention. Its clarity is graded as very slightly included, evaluated at eye level, meaning minor natural inclusions are present but do not detract from the gem’s overall transparency or brilliance when set. The vivid color intensity is the ruby’s defining feature, a strong, saturated red produced by chromium trace elements, and the excellent polish enhances its surface lustre, allowing clean facet junctions and lively scintillation. This ruby has been heat treated, a standard and widely accepted enhancement in the trade, applied to stabilize and deepen color and improve apparent clarity. Heat treatment in rubies is a stable treatment that, when properly disclosed, preserves value while making fine stones more wearable and visually appealing. For buyers who prioritize provenance and documentation, The Natural Ruby Company can provide full disclosure of treatment, origin, and can assist with third party gemological reports on request.

The journey of this ruby from mine to market is a careful story of selection, skill, and stewardship, narrated by The Natural Ruby Company every step of the way. Mined in Mozambique, this rough was identified by experienced field prospectors for its color potential, then sorted and prepared for cutting by skilled lapidaries who specialize in maximizing color and weight in cushion forms. After cutting it received precision faceting to the mixed brilliant design, followed by meticulous polishing to achieve an excellent finish, and a controlled heat treatment to enhance its vivid red tone. Each stage was photographed and recorded, allowing traceability from the mine to our inventory, and the finished gem was evaluated under standardized lighting and magnification to confirm its 3.52 carat weight, exact dimensions, clarity at eye level, and color intensity. For collectors and connoisseurs, this ruby represents a rare combination of size, vivid color, and eye-clean appearance in a classic cushion silhouette, making it ideal for a signature solitaire, bespoke engagement ring, or investment grade collection. The Natural Ruby Company stands behind its quality, offering transparent information, optional certification, and guidance on setting and care to preserve the gem’s beauty for generations.
