3.64 Ct. Ruby from Mozambique

This 3.64 carat oval ruby, measuring 11.61 x 7.85 x 4.24 mm, exemplifies the balance of weight and face up presence that educated buyers seek, with transparent material and a vivid red color intensity that commands attention. Cut in a mixed brilliant style to combine the scintillation of brilliant facets with the color retention of step facets, this stone has been skillfully proportioned to preserve carat weight while optimizing color and light return. Clarity is graded included at eye level, which indicates natural internal features are visible to a trained observer, yet do not obscure the gem's visual appeal, and they serve as fingerprint evidence of natural formation. The surface finish is an excellent polish, delivering crisp facet junctions and a clean table that enhances the stone for photographic or jewelry display. This ruby is heat treated, a widely accepted and stable enhancement that improves color and clarity by dissolving silk and altering chromium and iron related color zoning, and the treatment has been applied under controlled conditions to ensure permanence.

The story of this ruby from mine to market begins in Mozambique, a source that has produced many intensely colored red rubies in recent years, and continues through careful steps that matter to a discerning buyer. The rough crystal was recovered from a Mozambican deposit, carefully documented and selected for its transparency and potential to yield a high quality oval. Skilled cutters evaluated the rough to determine an optimal mixed brilliant design that would maximize vivid color while conserving weight, then executed precise faceting and an expert polish. The piece underwent standard and transparent heat treatment, followed by gemological inspection for clarity, measurements, carat weight, polish and overall finish. At The Natural Ruby Company we photograph and document each stone, and provide guidance on settings that accentuate the face up color, such as yellow gold for warmer contrast or platinum for a modern cool backdrop. With a hardness near 9 on the Mohs scale and stable heat treatment, this ruby is suitable for daily wear when set securely, and routine care with a soft brush and mild cleaner will maintain its brilliance. For the educated buyer this 3.64 carat Mozambican ruby represents a compelling combination of natural origin, vivid saturation, thoughtful cutting, and transparent disclosure from mine to market, offered by The Natural Ruby Company.
