Product description

One exceptional gem we are pleased to offer from The Natural Ruby Company is a semi translucent Intense Red ruby, C.Dunaigre certified, weighing 21.70 carat. This oval shape ruby measures 16.12 x 12.76 x 10.19 mm, and is fashioned as a cabochon cut to showcase a deep, even body color and a silky surface glow. The lab color classification is Intense Red, and the stone exhibits an intense color intensity that is highly desirable for collectors and connoisseurs. Clarity is graded slightly included when evaluated at eye level, which is typical and expected for natural rubies of this size and origin, and the finish is an excellent polish that gives the stone a smooth, reflective dome. There is no enhancement reported, the ruby is untreated, and its origin is Mozambique, a source noted for producing rich red rubies with strong saturation and attractive character.

As a member of our curated selection at The Natural Ruby Company, this 21.70 carat Mozambique ruby makes a striking focal point for bespoke jewelry, museum pieces, or investment collections. The cabochon shape emphasizes the gem’s color depth and luminous presence, making it ideal for a bold ring, a pendant that captures light and attention, or a centerpiece in a custom brooch. Its semi translucent nature gives a warm inner glow under light, and the slightly included clarity lends authenticity and natural charm. The C.Dunaigre certification accompanies the stone, confirming the no enhancement status and the Intense Red classification, providing confidence in provenance and quality. For care and setting recommendations, we suggest protective bezel settings for daily wear, gentle cleaning with mild soap and water, and avoiding harsh chemicals or ultrasonic cleaners to preserve the polish and surface integrity. Our team at The Natural Ruby Company is available to discuss custom designs, setting options, and secure shipping, and we can provide detailed imagery and certification documents upon request to help you make an informed and confident purchase.
