21.57 Ct. Cabochon Ruby from Mozambique

At The Natural Ruby Company we are pleased to present a striking translucent red ruby, a large and elegant cabochon that commands attention. This oval gemstone weighs 21.57 carats, and measures 21.00 by 15.30 by 6.40 millimeters, making it a substantial and wearable stone for a bold center in a ring or a dramatic pendant. The cabochon cut emphasizes the stone's glassy surface and internal glow, producing a soft, domed silhouette that is both classic and contemporary. Color is intense, a rich pure red with gentle hints of burgundy under certain lights, and the polish is excellent, yielding a mirror like finish on the dome. The stone is translucent rather than fully transparent, which allows light to penetrate and refract internally, creating a warm, luminous depth that is particularly attractive in natural rubies. This material originates from Mozambique, a source known for producing rubies with vibrant color and attractive body tone. Enhancement is limited to heat treatment, a widely accepted and stable process used to enhance color and clarity, and the clarity grade is slightly included when evaluated at eye level, indicating natural internal characteristics that confirm the stone is a natural ruby rather than a synthetic or wholly flawless laboratory product.

From a gemological and practical perspective, this Mozambique ruby shows the positive attributes collectors and designers seek in cabochon rubies. The slightly included clarity means there are internal features visible to the unaided eye, which can include fine needles, silk, or small crystal inclusions, and these features often contribute to the gemological fingerprint that can trace the stone to its natural origin. Heat treatment in this instance has harmonized color distribution and moderated any brownish overtones, elevating the intense red that you see, while the skilled lapidary has preserved weight and shape in the cabochon form, delivering excellent polish and smooth contours. The cabochon shape is forgiving in daily wear, and the robust dimensions make it suitable for strong settings such as bezel mounts, high domed prongs, or custom artisan designs. Consider pairing this rich red cabochon with warm metals, yellow gold or rose gold will enrich and enhance the warmth of the ruby, while white gold or platinum will provide a striking modern contrast that emphasizes the stone as the focal point. This gem will transition well from statement jewelry to heirloom quality pieces, and the natural inclusions tell a story that many collectors find desirable.
