Zoisite is a calcium aluminum hydroxyl sorosilicate mineral belonging to the epidote group. It naturally occurs in a range of colors and is notably recognized for its transparent blue-violet gemstone variety, known as tanzanite. This highly valued gem variety was first identified near Mount Kilimanj...
Why this score?
Mineral species benefits from tanzanite's fame, though non-tanzanite zoisite is far less prized.

The Callanish Standing Stones, also known as Calanais, are a Late Neolithic megalithic monument located on the Isle of Lewis in the Outer Hebrides of Scotland. Constructed around 2900 BC, the site consists of a central stone circle featuring 13 large rocks, with single avenues of smaller stones radi...
The Old Stone Mill National Historic Site is a historic water-powered gristmill located in Delta, Ontario, Canada. Constructed in 1810, the building is a notable early example of industrial architecture utilizing the automated milling system developed by Oliver Evans. It functioned as a commercial m...
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.

Backbone.js is a lightweight framework that provides structure to web applications. It follows the Model-View-Separation (MVS) pattern and offers features like models, collections, views, and events. While it may not have as many built-in features as other frameworks, its flexibility makes it suitab...
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
Andalusite is an aluminum silicate mineral with the chemical formula Al2SiO5. It forms in metamorphic rocks and is named after Andalusia in southern Spain. Gem-quality andalusite is valued for pleochroism, meaning that its apparent color changes when viewed from different directions. A related varie...
Marcasite is an iron sulfide mineral with the chemical formula FeS2 and an orthorhombic crystal structure. It has a pale metallic appearance that can resemble pyrite, but marcasite is less stable and may deteriorate when exposed to moisture or air. The name is also used in jewelry contexts, where sm...
Why this score?
Classic vintage jewelry material with metallic sparkle; usually pyrite in trade and lacks rarity or fine-gem prestige.
Scoring methodology
Cavansite is a blue calcium vanadium silicate mineral valued by mineral collectors for its intense color and well-formed crystal groups. It commonly appears as radiating or botryoidal aggregates and is softer and more fragile than many traditional jewelry minerals. Important specimens have been foun...
Pietersite is a brecciated quartz aggregate in which fragments related to tiger’s-eye and hawk’s-eye are cemented together. Its fibers can produce chatoyant reflections, while the broken structure creates irregular bands and swirling patterns in blue, brown, gray, and gold tones. The material was fi...
Magnesite is a mineral composed primarily of magnesium carbonate, with the chemical formula MgCO3. It commonly occurs in white, grey, or pale brown masses and has a dull to glassy appearance, although some material is cut and polished for ornamental objects and jewellery. Magnesite is also frequentl...
Why this score?
Common soft material often dyed as turquoise simulant; low durability and imitation reputation depress consensus.
Scoring methodology
Rhodochrosite is a manganese carbonate mineral with the chemical formula MnCO3. It ranges from pale pink to rose-red and can occur as crystals, granular masses, or curved and concentric bands; the banded material is cut for cabochons and ornamental objects. Colorado designated rhodochrosite its offi...
Clinozoisite is a calcium aluminium silicate hydroxide mineral in the epidote group. It is the monoclinic polymorph of zoisite, so it has the same chemical composition as zoisite but a different crystal structure. It forms mainly in metamorphic rocks and occurs in colors including green, yellow, gre...
Pargasite is a valid amphibole mineral named after Pargas, Finland, where it was first described in 1814. It is an aluminium-bearing, sodium-calcium amphibole found in igneous and metamorphic rocks, including amphibolites, marbles, and calc-silicate rocks. Well-formed crystals can be green, brown, o...
Rosasite is a secondary copper-zinc carbonate hydroxide mineral with the approximate formula (Cu,Zn)2CO3(OH)2. It commonly forms blue, blue-green, or green botryoidal, mammillary, or fibrous crusts in the oxidized zones of copper and zinc deposits. First described from the Rosas Mine near Narcao in...
Fuchsite is a chromium-bearing variety of muscovite, a member of the mica group of sheet silicate minerals. Trivalent chromium replaces part of the aluminum in the muscovite structure and produces its characteristic light to emerald-green color; the mica cleavage gives many specimens a sparkling or...
