Roscoelite is a rare vanadium-rich mica mineral typically found in metamorphic rocks and hydrothermal veins. It usually appears as thin, green to dark green sheets with a pearly to vitreous lustre, often forming delicate, flaky layers.

Rutile is a titanium dioxide mineral commonly found in igneous and metamorphic rocks, often forming as needle-like inclusions within quartz or other gemstones. It typically appears golden, reddish-brown, or black with a metallic to adamantine lustre, creating striking patterns known as "rutilated” quartz.

Sapphire is a precious gemstone, a variety of corundum, typically found in metamorphic and igneous rocks such as basalt and schist. It commonly appears in deep blue, though it can occur in a spectrum of colours, with a brilliant vitreous lustre and exceptional hardness.

Scheelite is a calcium tungstate mineral typically found in contact metamorphic skarns and hydrothermal veins. It often forms tetragonal crystals or granular masses, displaying colours from colourless and white to pale yellow, brown, or even blue under ultraviolet light, with a brilliant adamantine lustre.

Selenite, often found in the Satin Spar variety, is a crystalline form of gypsum typically occurring in sedimentary evaporite deposits. Satin Spar is recognised for its fibrous, silky texture and pearly to vitreous lustre, often appearing colourless to white, sometimes with subtle striations.

Serpierite is a rare copper zinc sulphate mineral typically found in the oxidised zones of copper deposits. It usually forms bright blue to turquoise crystalline crusts or aggregates, often with a vitreous to silky lustre, creating striking and vibrant specimens.

Shattuckite is a rare copper silicate mineral typically found in the oxidised zones of copper deposits, often alongside malachite and azurite. It usually forms striking deep blue to turquoise fibrous or radiating crystalline clusters with a silky to vitreous lustre.

Siderite is an iron carbonate mineral commonly found in sedimentary and hydrothermal environments, often associated with quartz, calcite, and fluorite. It typically forms rhombohedral crystals or massive granular aggregates in shades of brown, yellow, or grey, with a pearly to vitreous lustre.

Silver on matrix is a striking natural combination where native silver forms within or upon host rocks such as quartz or calcite. It typically appears as bright, metallic veins or branching filaments contrasting beautifully against a lighter stone background. Geologically, it forms in hydrothermal veins and secondary enrichment zones.

Soapstone is a metamorphic rock composed mainly of talc, giving it its signature soft, silky texture and smooth, soapy feel. It forms under intense heat and pressure, often displaying gentle shades of grey, green, or cream with elegant marbling. Prized since ancient times for carving and cookware, it carries folklore of peace and endurance.

Specularite, also known as specular hematite, is a shimmering variety of hematite formed in hydrothermal and metamorphic environments. It features dark steel-grey to black crystals with a brilliant metallic sheen that sparkles in the light, giving it a mirror-like appearance. Geologically rich in iron, it often occurs alongside quartz.

Spinel is a vibrant gemstone mineral commonly found in metamorphic rocks such as marble and gneiss, as well as in alluvial deposits. It occurs in a wide range of colours, including red, pink, blue, and violet, with a brilliant vitreous lustre and exceptional clarity. 

Stibnite is a striking antimony sulphide mineral typically found in hydrothermal veins and hot spring deposits. It forms long, slender, metallic-grey to silver-black crystals with a brilliant metallic lustre, often creating dramatic, reflective clusters.
