3.57 Ct. Ruby from Mozambique

There is a special kind of magnetism about a classic ruby that has been prized by civilizations for millennia, and this purplish red oval from Mozambique carries that same timeless authority, presented by The Natural Ruby Company. At 3.57 carat, measuring 10.76 x 8.59 x 3.73 mm, this transparent gem sits in the long tradition of regal jewels that have been passed down through generations, a piece that speaks to lineage and refined taste. Its vivid color intensity recalls the deep hues found in historical treasures, and its excellent polish brings each facet to life, allowing light to dance across the surface with an aged elegance that feels both historic and immediate. The mixed brilliant cut was chosen to honor classic proportions while embracing modern craftsmanship, ensuring the stone can be set in heirloom rings, pendants, or bespoke pieces that will endure as family icons. Evaluated at eye level, the clarity is included, and these internal characteristics are not flaws so much as signatures of natural origin, adding character and a sense of provenance, with a responsible enhancement of heat treatment applied to stabilize and enrich the color for lasting beauty.

Beyond its storied appeal, the structure of this ruby is what gives it a sparkle that is unmatched by many other gems, and understanding that structure illuminates why it captivates so completely. Ruby is a variety of corundum, crystallizing in the trigonal system with a dense atomic lattice that produces a relatively high refractive index around 1.76 to 1.77, and a small but measurable birefringence. Those optical properties, combined with the precise geometry of a mixed brilliant cut, yield intense internal reflection and scintillation, while the brilliant facets on the crown and pavilion interact with the stone s light to generate flashes of brightness and depth. The excellent polish enhances these effects by smoothing facet junctions to allow maximum light return, and the stone s internal inclusions can scatter light in subtle ways that produce a velvety glow and depth of color unique to natural rubies. For those who cherish legacy, this Mozambique ruby from The Natural Ruby Company is not only a jewel of remarkable hue and cut, it is a living link to the ancient language of gemstones, ready to be set, cherished, and handed down.
