Rockbridgeite

Elpidite is a hydrated sodium zirconium silicate mineral. Crystal fibrous, always in a white to yellowish color. Most of the notable specimens came from the famous Mont Saint-Hilaire Mine, Canada. The name of this mineral came from the Greek word "hope", it was a new mineral found in a potential Greenland mine, the researchers who named it hoped more new minerals would be found.

Leucophosphite occurs in a variety of colors, including greens, yellows, purples, and browns. This mineral is usually transparent or translucent and relatively soft. Leucophosphite can either be the result of chemical reactions with bird or bat excrement or be formed with iron-rich deposits. The fracture is brittle and the streak is white.

Glaucodot is a metallic mineral characterized by its opaque appearance and grayish tin-white color. It is found in hydrothermal deposits, often together with other minerals such as Pyrrhotite and Chalcopyrite. It was once used for making an ornamental, deep-blue cobalt glass called "smalt".

Epididymite is a hydrated sodium beryllium silicate. It shares the same chemical composition with eudidymite but with a different crystal structure. The name of it derives from the Greek word "near" and "twin", representing "the relationship with eudidymite" and "the habit that it always occurs in twins" respectively.

Howlite tumbled is a white stone with veins of black or dark grey running throughout its polished surface. This stone is valued for its marble feel and ability to take dye. First found in Canada, howlite tumbled is now mined in the USA, Brazil, and South Africa. It is often made into decorative objects and when dyed blue, it resembles turquoise.

Garnets ( /ˈɡɑːrnɪt/) are a group of silicate minerals that have been used since the Bronze Age as gemstones and abrasives. All species of garnets possess similar physical properties and crystal forms, but differ in chemical composition. The different species are pyrope, almandine, spessartine, grossular (varieties of which are hessonite or cinnamon-stone and tsavorite), uvarovite and andradite. The garnets make up two solid solution series: pyrope-almandine-spessartine (pyralspite) and uvarovite-grossular-andradite (ugrandite).

Angelite is a blue-gray variety of the mineral known as Anhydrite, and its unique coloration makes it a highly popular in the gemstone trade. It is rarely faceted, more often used for carved, ornamental objects and polished cabochons. The only known locality of angelite is Peru, where it was first discovered in the late 1980s.

Moonstone is a popular commercial name for any Moonstone that features a color other than white. Moonstone comes in several colors and it's prized for the "unearthly" shine particularly emphasized in cabochon cuts. Its multicolored variety, also known as Rainbow Moonstone, is made from the material mined in Sri Lanka and Southern India.
