INDIAN QUARTZ CRYSTAL


The quartz gemstone is probably one of the most popular and versatile gemstones that are available. Quartz is a rock crystal and has been in use since ancient times. Despite the most sought varieties of quartz like citrine, amethyst, rose quartz, agates, ametrine, chrysoprase, onyx and rutilated quartz, there are many other varieties available too. These gems are affordable and stand apart from expensive gemstones like jade and diamonds.

Quartz Gemstone
Quartz is said to be the second most common mineral found on the Earth’s crust after feldspar. Quartz is made up of silicon oxygen tetrahedra. The word quartz is derived from the German word ‘quarz’ which means ‘cross-vein ore’. In ancient times in the Middle East and Europe, quartz was used in jewelry. Quartz was not only used for jewelry, but was a major element to be used in scientific experiments.

There are a few varieties of quartz like purple to violet amethyst and yellow to golden or orange citrine. A particular variety of quartz called drusy quartz with its surface which is covered by tiny sparkling crystals is a very unusual piece of jewelry.
