3.31 Ct. Ruby from Mozambique

This ruby began its journey deep within Mozambique, in deposits known for producing stones with lively color and strong transparency. The rough crystal was recovered from alluvial concentrations, lifted from weathered gravels where months of careful excavation revealed its presence. The rough exhibited an attractive pinkish red tone and a transparent body, qualities that indicated potential for a premium finished gem. From the outset, selections were made with attention to natural habit and internal structure, so that subsequent cutting would preserve both weight and color saturation. Our team at The Natural Ruby Company documented the piece at the mine, recording weight and visible characteristics, and arranged transport under secure handling procedures designed to maintain the stone integrity until it reached the cutting atelier.

In the cutting studio, master cutters assessed the rough and chose a cushion outline to balance dimensions and face up area, while selecting a mixed brilliant cut strategy to enhance table brilliance and internal light return. The final weight measures 3.31 carats, and the finished dimensions are 12.31 by 8.01 by 3.55 millimeters. During cutting, decisions were oriented toward maximizing vivid color intensity and maintaining transparency, while minimizing unnecessary removal of material that would reduce carat weight. The stone was subjected to a controlled heat treatment designed to stabilize and intensify the ruby color and to improve overall clarity. The finished gem presents a clarity grade of included, evaluated at eye level, which is consistent with natural internal features that do not significantly impede visual performance. The polish was completed to an excellent standard, resulting in crisp facet junctions and a smooth reflective surface that supports lively light interaction across the mixed brilliant pattern.

Following cutting and finishing, the ruby underwent a systematic quality assessment by The Natural Ruby Company. Measurements were verified, color and clarity grading was recorded, and the enhancement status was documented as heat treated. Origin was attributed to Mozambique, based on miner provenance and characteristic material properties, and this information has been included in our internal provenance record. High resolution imaging and careful photographic documentation were completed to show the stone face up and in profile, enabling designers and clients to evaluate proportions and color behavior. The gem presents a vivid color intensity that will retain presence in a variety of settings, and its transparent nature combined with the mixed brilliant cut makes it suitable for ring centers, pendants, or bespoke pieces where a rich hue and noticeable presence are desired.

The Natural Ruby Company presents this ruby as a piece ready for incorporation into refined jewelry designs, accompanied by clear documentation of its technical specifications and treatment history.

For practical considerations, heat treated rubies are stable under normal wear conditions, and recommended care is limited to routine gentle cleaning with warm water and mild detergent, avoiding prolonged exposure to harsh chemicals or extreme heat. The documented journey from Mozambican deposit to finished gem reflects attention to material selection, skilled cutting, and rigorous quality control, offering a clear and traceable provenance for clients and designers who prioritize detailed technical information and material authenticity.
