Demantoid garnet is a rare gemstone belonging to the andradite group. It’s notable for its exceptionally high dispersion, creating brilliant flashes of color when light passes through it. This intense fire makes Demantoid highly sought after by jewelry collectors and gem enthusiasts who appreciate u...
Andradite is a calcium-iron nesosilicate mineral species belonging to the garnet group. It forms in contact metamorphic rocks and occurs in several distinct gemstone varieties, including green demantoid, yellow topazolite, and black melanite. The demantoid variety is particularly noted by mineralogi...
Why this score
Species includes demantoid, among the most prized garnets; variable varieties make overall consensus slightly mixed.
Scoring methodology
Sphene, formally known as titanite, is a calcium titanium nesosilicate mineral valued as a collector's gemstone. It is distinguished by its exceptional dispersion, meaning faceted stones exhibit a fiery, multicolored scintillation that exceeds that of diamond. Sphene typically occurs in green, yello...
Sphalerite is a zinc sulfide mineral (ZnS) and the chief ore of zinc. Transparent specimens are faceted into collector's gemstones, noted for high dispersion exceeding that of diamond. Notable sources include Spain and Mexico, and its colors range from yellow and red to brown and black.
Why this score
Exceptional dispersion and brilliance impress collectors; softness, cleavage, and rarity of clean stones limit jewelry use.
Scoring methodology
Cerussite is lead carbonate, a mineral formed mainly in the oxidized zones of lead-bearing ore deposits. It crystallizes in the orthorhombic system and commonly appears as colorless, white, gray, or pale-colored crystals; twinned forms are a familiar feature of specimens. With a specific gravity of...
Why this score
Exceptionally bright, dense collector crystals can be stunning; softness, brittleness, and lead content hurt jewelry value.
Scoring methodology
Cassiterite is the naturally occurring mineral form of tin(IV) oxide, with the chemical formula SnO₂, and it is the principal ore of tin. It is usually brown, reddish brown, black, or otherwise dark, with a tetragonal crystal structure, Mohs hardness of about 6 to 7, and a high specific gravity near...
Why this score
High refractive index and collector faceting appeal; dark color, softness, and tin-ore identity limit broad desirability.
Scoring methodology
Zircon is a naturally occurring mineral composed mainly of zirconium silicate, with the chemical formula ZrSiO4. It crystallizes in the tetragonal system and commonly forms durable crystals in igneous rocks, metamorphic rocks, and sedimentary deposits. Transparent varieties can be cut as gemstones a...
