4.03 Ct. Cabochon Ruby from Mozambique

This listing describes a translucent, C.Dunaigre certified red ruby weighing 4.03 carats, presented in a cushion shape with sugar loaf cabochon styling, with dimensions 10.17 x 8.59 x 4.59 mm. The gem displays a pinkish red hue with intense color intensity, and the lab color classification is red. Clarity is graded as slightly included when evaluated at eye level, which is consistent with natural rubies and often indicates internal silk or small mineral inclusions that contribute to the stone being natural and untreated. The polish is excellent, producing a lively, even reflection across the domed surface, and the stone is documented as having no enhancement, which significantly increases its desirability for collectors and connoisseurs seeking natural material. The origin is Mozambique, a source known for producing large, intensely colored rubies in recent years, and the certificate from C.Dunaigre confirms both identity and the absence of treatments.

For the educated buyer, this ruby is attractive for several reasons. Untreated rubies with intense red tone and translucency are rare compared with heat treated or otherwise enhanced stones, and a 4.03 carat example presents a meaningful size for either a bespoke jewelry commission or a direct addition to a collection. The cushion sugar loaf cut prioritizes color saturation and face up appeal, allowing the depth and tone to read strongly even with the cabochon profile. Slightly included clarity is expected in natural rubies of this character, and these inclusions often act as fingerprint evidence of origin and natural growth, aiding long term valuation. The Mozambique origin adds context for provenance and market positioning, as material from this region has gained recognition for its combination of vibrant color and larger crystal sizes. The absence of enhancement is particularly important for resale and investment, because untreated stones typically command a premium and maintain clearer documentation of market value.
