5.73 Ct. Rhodonite from Brazil

One transparent 5.73 carat oval red rhodonite, dimensions 13.26 x 9.09 x 5.84 mm, presented in a mixed brilliant cut with excellent polish. The stone shows vivid color intensity and a clarity grade of slightly included as evaluated at eye level, originating from Brazil, and free of any enhancement. The mixed brilliant faceting has been chosen to maximize return of light for a stone of this species, balancing a generous table with well proportioned pavilion facets to sustain a strong face up presence while preserving the saturated red tone. Under standard viewing conditions the gem displays a warm, even red that reads consistently across the table, while the slight inclusions are minor in impact, appearing as soft, internal features that do not dominate the overall visual appeal.

In terms of reflective qualities the transparent red rhodonite is best described as having a vitreous to slightly satiny sheen, with internal light return that produces a steady, glowing radiance rather than high dispersion flashes. Compared with corundum based rubies, this rhodonite exhibits less brilliance and markedly lower fire, rubies commonly presenting a tighter, more scintillating return due to a higher refractive index and stronger dispersion. Against spinel and some garnet varieties, the rhodonite offers a more diffused, warmer glow, while spinel tends to show crisper facet definition and garnet often delivers more vivid flashes in dark to medium tones. Tourmaline varieties that approach this color range will typically show more layered color and pleochroism, whereas this rhodonite reads as a uniform single tone with subtle internal reflections. For settings that favor a rich, gemlike red without the sharp sparkle of corundum, and for collectors interested in an unenhanced, transparent example from Brazil, this piece from The Natural Gemstone Company presents a distinctive combination of color saturation, clean face up appearance, and a restrained, elegant light performance.
