About this item

  • You will receive exactly this Blue Turquoise Rough Set (see photo, the photos are taken under bright light)! Set Weight: 3.6g / 0.13 oz / 18 Carat.
  • Named from French "turques" or "turquois" meaning "Turkish" the original material found on the south slopes of the Al-Mirsah-Kuh Mountains (Iran), but which found its way to Europe via Turkey. The name was known at least as early as the 17th century C.E. Turquoise and members of its group were redefined by Foord and Taggert in 1998, with turquoise reserved for an end-member composition.
  • Turquoise is an opaque mineral that occurs in beautiful hues of blue, bluish green, green, and yellowish green. It has been treasured as a gemstone for thousands of years. Isolated from one another, the ancient people of Africa, Asia, South America and North America independently made turquoise one of their preferred materials for producing gemstones, inlay, and small sculptures.
  • Chemically, turquoise is a hydrous phosphate of copper and aluminum (CuAl6(PO4)4(OH)8·5H2). Blue minerals are rare, and that is why turquoise captures attention in the gemstone market. The most desirable color of turquoise is a sky blue or robin's-egg blue.
  • Howlite has the appearance of white marble or porcelain with a sub-vitreous lustre. It is opaque and white or grey with grey, black or dark brown veins running through it. Gemstone quality howlite can be interspersed by the darker matrix (which appears as the veins), or it can be matrix-free and pure white. Howlite is best known for imitating other gemstones.
