21.70 Ct. Cabochon Ruby from Mozambique

If you are searching for the perfect natural ruby that ends your quest for color, weight, and provenance, this C.Dunaigre certified intense red ruby answers that need with authority. We present a semi-translucent, cabochon cut oval ruby weighing 21.70 carats, with dimensions of 16.12 by 12.76 by 10.19 millimeters, offering a substantial and commanding presence for collectors or for a truly exceptional engagement or statement piece. The gem displays an intense red lab color classification, a richness that the cabochon cut amplifies by smoothing light across the surface and deepening the visual saturation, while an excellent polish gives a reflective, glassy finish. Clarity is graded slightly included at eye level, which in a natural, untreated ruby of this size and origin contributes to its character and authenticity, and importantly, this stone has no enhancement, assuring you of its natural beauty as mined in Mozambique.

For those whose needs include documented provenance, stable value, and immediate readiness to set into a bespoke design, the C.Dunaigre certificate accompanies this ruby, verifying its origin and lab color classification as Intense Red, and confirming the absence of any treatment. This makes it an ideal solution whether you are finalizing an engagement ring and demand a rare, untreated focal stone, or you are a collector seeking a museum quality specimen with credible documentation. At The Natural Ruby Company we understand that acquiring a ruby is both an emotional and an investment decision, and we recommend this 21.70 carat cabochon for a dramatic pendant, a bold unisex signet, or a bespoke ring that highlights the gem's semi-translucent depth. We are ready to advise on settings that protect and enhance the cabochon form, and to provide further imagery and certification details so that your purchase is confident and complete.
