21.70 Ct. Cabochon Ruby from Mozambique

This 21.70 carat oval red ruby presents as a semi translucent cabochon with dimensions of 16.12 x 12.76 x 10.19 mm, exhibiting a smooth domed profile and consistent mass suitable for a range of mounting options. The stone is from Mozambique, and it displays an intense red color with excellent polish, attributes that contribute to strong visual appeal under varied lighting. Clarity is graded as slightly included when evaluated at eye level, with natural internal features typical of rubies that do not detract from the overall saturation and depth of tone. The piece is untreated, with no enhancement reported, preserving its natural character and making it a desirable specimen for collectors and connoisseurs who prioritize provenance and authenticity.

From an investment perspective this ruby represents several favorable factors that support potential future appreciation in value. Size is a primary driver of ruby pricing, and a 21.70 carat unenhanced example with intense color is comparatively rare in the market, particularly from Mozambique where high quality material has been increasingly sought after. The combination of substantial weight, natural color concentration, and excellent polish enhances marketability across collectors and high end jewelers, and the absence of treatments sustains its long term desirability and resale potential. Market dynamics for natural rubies historically reflect strong performance during periods of constrained supply and rising demand for untreated stones, and quality examples with clear provenance such as this one are often viewed as hedges against inflation and currency fluctuation for diversified tangible asset portfolios. The Natural Ruby Company offers documentation of origin and grading observations, which supports transparent valuation and facilitates future resale or consignment. Prospective investors should consider long term holding horizons, certification options from recognized gemological laboratories, and secure storage as part of an overall acquisition strategy.
