Just like in the jewellery of today, gorgeous stones, colourful and rare, are most often the outstanding style of a piece with a metal setting for adornment. The gemstones used by the craftsman of fine jewellery are normally divided into two grades “semi-precious stones” and “precious stones”.
These terms are used severely in the commercial world of jewellers when considering value and variety. While the artistic deserve is only a matter of opinion, the worth of a stone is what it will bring in the business. It has to also be mentioned that many people, general shopper and collectors alike, favour the rare to the gorgeous. These stones are simply minerals taken from the mine, and after they have been enhanced by the craftsman cutting and polishing, rarest and the best of them are what we call gems.
The generally precious stones are the rubies, sapphires, emeralds and diamonds. The pearl is potentially grades with precious stones. Although seriously speaking while it is not a gemstone it holds an adoring place in jewellery.
A major number of gemstones used in jewellery are known-well as semi-precious; the largely important ones are as follow: amethyst, alexandrite, lapis-lazuli, turquoise, peridot, chrysoberyl , topaz, moonstone, peridot, zircon, opal, tourmaline, amethyst aquamarine. Others of small importance although much used are as follow: jade, garnet, bloodstone, agate chrysoprase, carnelian, azurite, malachite, coral and many others.
These gemstones while rather common and low-priced are necessary to the worker in jewellery. The varieties of colours to be had in these gemstones make it possible to generate uncommon designs of craftsman and to adapt them to the personality and costume of the jewellery.
Most gemstones are hard, but some soft minerals are used in jewelry because of their luster or other physical properties that have aesthetic value.
