Gemstone Beads |
Gemstones are hard pieces of attractive naturally-occurring materials that are cut and polished to be used in jewelry making and other adornments. Loose gemstones are generally referred to as gemstone beads used for making precious and semi precious jewelry. Most of the gemstone beads are hardened minerals. However, there are many gemstone beads that are made of rocks or other organic materials and are not minerals. Examples of such gemstones include lapis-lazuli /lapis-lazuli-beads.html which is made from a rock and amber beads that originate from organic materials. Further, most of the gemstone beads are hard but there are certain soft minerals too which are used for making gemstones due to their aesthetic value. Amber beads again are a very soft kind of gemstone beads.
Types of Gemstones
Gemstones are divided into two major categories based mainly on the value assigned to the particular gemstone beads. The two types of gemstones are precious gemstone beads and semi precious gemstone beads. /semi-precious-beads.html
Precious Gemstones
There are four precious gemstones- Diamond, Ruby, Emerald and Sapphire. These gemstone beads are precious from both- historical and contemporary perspective of gemology. The four major gemstones are considered precious beads due to their historical importance, rarity and their present market value. Three from among the four precious gemstone beads- Ruby, Emerald, and Sapphire- have colors that identify with the natural primary colors namely red, green and blue respectively. Diamond- the fourth precious gemstone is colorless but has a shine that sets it class apart. It is also the hardest of all gemstones (hardness of 8-10 on the Mohs scale.) It is perhaps for the reason of their much higher value that the precious gemstones are rarely traded in as wholesale gemstone by the gemstone beads suppliers. The precious gemstones are usually traded on basis of single piece or on their cumulative value after studding them into gemstone jewelry.
Semi Precious Gemstones
Semiprecious Gemstones make up the largest percentage of all gemstones. There is a great range of semi precious gemstone beads. All of these semi precious gemstone beads vary in value, color, quantity, and popularity. Although almost all of the semi precious gemstone beads are less expensive than precious gemstones, there are many which are rarer than the precious gemstones. Examples of such semi precious gemstone beads that are less expensive than precious gemstones in spite of being rare include alexandrite and spinel beads /spinel-beads.html among others. Due to their being lesser expensive, semi precious gemstone beads are produced on a wholesale basis by the gemstone beads manufacturers and also traded as wholesale gemstone beads by the gemstone beads suppliers
