We all go through some tough times in our lives. Times during which we do not get the results we want, for the efforts we put in and we have to struggle to even get to a bare minimum point. It surely dampens our hopes and makes us feel vulnerable. The best solution to turn these situations around is hard work, because without hard work there cannot be any success. Some people feel that luck plays a major role in our lives, and by wearing gemstones as rings or necklaces can turn the situation in our favour. We see advertisements almost everywhere about shops from where we can buy stones and contacts astrologers who can advice on the same.
What is a Gemstone?
A gemstone is a piece of mineral crystal, which, in its cut & polished form, is used to make jewelry or other adornments. Certain rocks like lapis lazuli, opal, jade, amber, jet, and pearl are also used for jewelry. Most gemstones are hard, but some soft minerals are used in jewelry because of their luster and other physical properties that have aesthetic value.
Classification of Gemstones : Gems are characterized in terms of their –

Do Gemstones have any value?
A mnemonic device, the ‘four Cs’ (color, cut, clarity, and carats), has been introduced to help the consumer understand the factors used to grade a diamond. While, other gemstones are still graded using the naked eye (assuming 20/20 vision). Physical characteristics that make a colored stone valuable are ;
In general, per carat, prices of larger stones are higher than those of smaller stones, but popularity of certain sizes of stone can affect prices. Typically, prices range from US$1/carat to US$20,000–50,000.
Synthetic and Artificial Gemstones :
It is important to distinguish between synthetic gemstones, and imitation or simulated gems. Synthetic gems are physically, optically, and chemically identical to the natural stone, but are created in controlled conditions in a laboratory.
Imitation or simulated stones are chemically different from the natural stone but may be optically similar to it; they can be glass, plastic, resins, or other compounds. Examples of simulated or imitation stones include cubic zircon, composed of zirconium oxide and simulated moissanite, which are both diamond stimulants. Synthetic, cultured, or lab-created gemstones are not imitations. For example, diamonds, rubies, sapphires, and emeralds have been manufactured in labs to possess identical chemical and physical
characteristics to the naturally occurring variety.
