A good quality unakite is considered a semiprecious stone; it will take a good polish and is often used in jewelry as beads or cabochons and other lapidary work such as eggs, spheres and animal carvings. It is also referred to as epidotized or epidote granite.
Crystal healing is a pseudoscientific alternative-medicine practice that uses semiprecious stones and crystals such as quartz, agate, amethyst or opal. Despite the common use of the term "crystal", many popular stones used in crystal healing, such as obsidian, are not technically crystals. Adherents of the practice claim that these have healing ...
Rhodochrosite is mainly used as an ore of manganese, which is a key component of low-cost stainless steel formulations and certain aluminium alloys. [9] Quality banded specimens are often used for decorative stones and jewellery.
Stones can also be placed in chilled water to achieve a temperature between -5 to 25 degrees Celsius (25 to 75 degrees Fahrenheit). The use of a calibrated thermometer is common and recommended to reach ideal temperatures. [5] In order to maintain adequate external skin hydration, massage oils or lotions are commonly applied to the client's ...
(However, the term prase is also used to describe chlorite-included quartz, and to a certain extent is a color-descriptor, rather than a rigorously defined mineral variety.) Chrysoprase is cryptocrystalline, which means that it is composed of crystals so fine that they cannot be seen as distinct particles under normal magnification.
Granitic rocks in general are of interest to geologists, geochemists, etc., because they provide 'crystallized' telltale clues of their environment of formation. [6]Alkali feldspar granite is used as construction material in the form of dimension stones, and polished slabs or tiles for building facades, pavements, and kitchen countertops.
Although other minerals such as tourmaline, scapolite, corundum, spinel and quartz can form "cat's eye" stones similar in appearance to cymophane, the jewelry industry designates these stones as "quartz cat's eyes", or "ruby cat's eyes" and only chrysoberyl can be referred to as "cat's eye" with no other designation.

A stone is ground into shape (often a cabochon or a short, wide cylinder) and polished to a shine. Sometimes the flat surface is engraved with a religious motto in Arabic, which is sometimes inlaid with gold. The finished gem is then mounted on a ring according to the stones finished size. Both men and women wear aqiq rings as jewellery.
