17.02 Ct. Cabochon Ruby from Mozambique

This translucent red ruby weighs 17.02 carats and presents a classic cushion outline combined with a cabochon cut, dimensions measuring 19.70 by 10.80 by 6.80 millimeters. The specimen has been assessed and recorded with a clarity grade of included when evaluated at eye level. The color registers as dark in intensity, offering a deep, saturated red hue that reads consistently across the dome of the cabochon. The surface finish is reported as excellent polish, contributing to a smooth, reflective profile that highlights the internal color and structure of the stone. This ruby is natural and untreated, with no enhancements reported, and its documented origin is Mozambique, information that supports both gemological context and provenance. This piece is offered through The Natural Ruby Company, where the emphasis is on accurate description and complete disclosure.

From a gemological perspective, the combination of weight, shape, and cut makes this ruby a notable example within collector and jewelry contexts. At 17.02 carats, the stone falls into a size range that significantly influences both visual presence and market categorization for corundum. The cabochon cut emphasizes color and translucency over facet driven brilliance, making the dark, saturated red the primary aesthetic attribute. Included clarity at eye level is consistent with many natural rubies of this scale and type, and it should be understood as a part of the stone structure rather than a condition diminishing intrinsic value. The excellent polish ensures that the cabochon surface communicates the hue and internal character in a refined manner, while the absence of enhancement confirms that the color and clarity are natural attributes tied to the rough material and origin.

The physical dimensions and cut of the ruby make it suited to a variety of settings that prioritize both protection and presentation. The cushion outline and length of nearly 20 millimeters along one axis allow designers to create a substantial center element for rings, pendants, brooches, or a multi stone composition. The cabochon profile reduces the risk associated with sharp facet junctions and concentrates stress uniformly across the dome, which can be advantageous in daily wear contexts when set with appropriate mounting that guards the girdle and culet areas. Corundum, the mineral family to which ruby belongs, is second only to diamond on the Mohs hardness scale, providing inherent durability that supports long term wear and intergenerational transfer. Careful setting design, regular inspections, and basic maintenance will preserve the polish and mounting integrity over decades.

Provenance and treatment status are central to the long term value and stewardship of a significant gemstone, and this ruby’s Mozambican origin and untreated nature are material factors in both. Mozambique is recognized for producing rubies with strong color saturation, and provenance documentation aids in authenticating the stone within secondary markets and institutional collections. The absence of heating or other enhancement simplifies assessment for conservation, insurance, and resale purposes, because untreated stones are often evaluated on a different basis than treated material. For custodial considerations, maintaining original documentation from The Natural Ruby Company, along with independent gemological reports when available, will facilitate future appraisal and transition. Routine professional cleanings and periodic setting checks are sufficient to maintain condition, and avoided exposure to abrasive chemicals or sustained high heat will protect polish and color quality.

These combined characteristics create the conditions for this ruby to function as a generational heirloom. Size and presence allow the stone to remain a focal asset through changing fashions, while the cabochon form offers classical simplicity that translates across design eras. Durability inherent to corundum supports repeated wear and resettings over time, permitting descendants to adapt the mounting to contemporary styles without compromising the gem itself. Natural, untreated status and verifiable Mozambican origin contribute to long term desirability, because they anchor the gem’s story in tangible attributes that can be conveyed through documentation and conserved photographs. With attentive care, mindful mounting choices that distribute stress, and retention of provenance records provided by The Natural Ruby Company, this 17.02 carat cushion cabochon ruby can be preserved, enjoyed, and passed forward as a meaningful family asset over multiple generations.
