Quartz is an extremely common mineral that can crystallize as a six-sided prism that ends with a six-sided pyramid. It is the second most common mineral, making up 12% of the earth's crust, though most quartz does not form crystals. (Sandstone, for instance, is made of quartz.) The crystallized form of quartz, which is an extremely hard mineral, is used to create jewelry. Quartz is easy to reproduce using a hydrothermal process and therefore many pieces of jewelry actually boast synthesized pieces of quartz. It is difficult to tell the difference between most naturally occurring quartz and its synthetic counterpart; however, natural quartz that boasts crystals of extremely high clarity is rare and very expensive.
There are many different varieties of quartz, from clear to opaque, and in many different colors. The most recognizable forms of quartz are amethyst, a violet crystal whose lucidity and color varies depending on where it is harvest; citrine, a yellow or a yellow-brownish color; rose quartz, a soft, pink colored crystal; and smoky quartz, a brown-colored quartz. Agate, ametrine, aventurine, jasper, onyx, and opal are also quartz gemstones.
The durability and strength of quartz gemstones makes them excellent for necklaces, bracelets, earrings, and rings. Quartz is relatively easy to care for and can be cleaned with warm, soapy water. Quartz is a mineral whose properties can change if it is exposed to chemical or extreme heat. Quartz gemstones will change color and lucidity if exposed to harsh household chemicals or drastic changes in temperature. Extreme temperature changes can also cause quartz to crack.
Jade is a term for different minerals: nephrite and jadeite. Jade is quickly recognizable as a beautiful, green gemstone used to make jewelry, figurines, vases, and dishes. It was first popular in China 5000 years ago. Its beauty and incredible durability made an ideal substance for the creation of tools, weapons, furnishings, and figures. Jade was considered incredibly valuable, even more valuable than silver or gold, and was owned only by the most wealthy, high-ranking families.
Jadeite is the rare form of jade and is considered more precious. Jadeite is often a beautiful green, but can also be white, pink, black, brown, violet, or red. Nephrite is most commonly apprised of various shades of green, but can also be red, yellow, or white. Often, a green stone will contain streaks of other colors, forming gorgeous, eye-catching patterns.
It has not been until recently that jade has been used for jewelry. Traditionally, jade had religious connotations, and was used to form cult figurines and other religious objects. Jade is a popular antique collector's item. Now, jade is making an appearance in necklaces, bracelets, and earrings. Different people are drawn to different types of hade: some prefer the bright greens while others enjoy the subdued greens imbued with streaks of white or violet. It's all a matter of personal taste!
