1.63 Ct. Chrome Diopside from Brazil

This listing from The Natural Gemstone Company presents a beautiful transparent chrome diopside weighing 1.63 carats, cut into a classic round shape with precise dimensions of 7.10 x 7.11 x 4.62 mm. The gem has been fashioned with a mixed brilliant cut, combining the fire and scintillation of brilliant facets on the crown with the depth control of a faceted pavilion, and it exhibits an excellent polish that maximizes surface reflection. The color is vivid, a saturated forest to deep apple green caused by chromium within the diopside structure, and the stone is reported as having no enhancement, which is of particular importance to collectors and connoisseurs who prioritize natural, untreated material. Clarity is graded as slightly included at eye level, meaning that small internal features are visible upon close inspection but do not dominate the visual experience, and the overall transparency remains high for a chrome diopside of this weight and saturation.

From a gemological standpoint this stone presents characteristics that make it both attractive and interesting to an educated buyer. Chrome diopside typically shows strong pleochroism, and in this piece observers will notice subtle shifts from cooler bluish greens to warmer yellow greens as the stone is rotated, which is enhanced by the mixed brilliant cut. Its refractive index is modest compared with higher sparkle gemstones, which results in a more restrained but elegant brilliance. The excellent polish and precise facet symmetry improve light return, creating a lively face up appearance despite the slightly included clarity grade. The gem demonstrates a vitreous lustre and crisp facet reflections, and because it is unheated and otherwise unenhanced its vivid chroma is a direct expression of its Brazilian origin, a provenance that is increasingly sought after for chrome diopside due to the quality and stability of material from that country.

When compared to other green gemstones in its category the reflective qualities of chrome diopside should be understood in context. Compared with tsavorite garnet, which has a higher refractive index and typically produces stronger brilliance and scintillation, chrome diopside offers a deeper, more saturated color at a more accessible price point, with reflections that are softer and more velvety rather than highly sparkly. Against emerald, chrome diopside often exhibits superior transparency and cleaner face up appearance because fine emeralds frequently contain dense inclusions that interrupt light flow, so a vivid, transparent chrome diopside like this will present a richer apparent color and more even reflections. Compared with green tourmaline, which can display bright facet reflections but tends toward cooler green tones, this chrome diopside returns light with a warmer, greener glow and shows a strong internal color saturation that can appear almost lamp like under direct light. Overall the reflective signature of this gem is characterized by a satiny brilliance and deep color saturation rather than the pinpoint sparkle associated with gems of higher refractive index.

For the discerning buyer this gem represents a compelling combination of size, color, and natural integrity. At 1.63 carats this round, mixed brilliant chrome diopside is large enough to be the focal point of a ring or pendant, and the vivid, unenhanced coloration from Brazil provides both visual appeal and investment interest. Slight inclusions evaluated at eye level are common in diopside and do not materially detract from the stone when set, while the excellent polish and well executed cut ensure attractive light performance. Buyers should be aware that chrome diopside has moderate hardness relative to other gem materials, so appropriate settings and occasional professional cleaning will preserve the gem s finish. If you value natural color, ethical sourcing, and a gemstone that balances color intensity with an understated, elegant brilliance, this chrome diopside is an excellent selection, and The Natural Gemstone Company is pleased to offer it with full disclosure of origin, weight, cut, clarity, and lack of enhancement.
