5 Common Gemstones Used In Jewellery

28/05/2022 | Softran Team

The process of cutting and polishing gems is an ancient art, which continues to be an important part of jewellery manufacturing today. Gemstones are usually classified in one of two ways: by the type of mineral from which they are sourced, or by their optical properties. Natural gemstones are classified into three basic groups:

Precious gems, are very rare and do not occur frequently in the Earth’s crust. Their value is not only because of their beauty but also because of their rarity.

Semi-precious gems, are more common and are also used for jewellery and other ornamental purposes.

Uncut gems, are not used for other purposes and are sold as uncut stones.

Gemstones are usually cut into cabochons or faceted gems. Cabochons are stones that have been polished and have only one flat polished face. Faceted gems have many polished faces, or facets, and are usually cut from a flat-bottomed rock crystal (rock crystal is also known as natural transparent quartz since it is colourless).

Some gemstones are used for specific purposes. For example, diamonds and rubies are used in making engagement rings, due to their exceptional optical and physical properties. Another example is sapphires and emeralds.

Numerous gemstones are used in jewellery, and most of them have been cut and polished to look like those that you see in fine jewellery. The top 5 stones are;

 

DIAMOND

The sophistication and durability of a diamond mean that it is the most valuable gemstone for jewellery. Its origins can be traced back to 3500 BC in India. Yet despite their age, diamonds are still a popular choice for engagement rings and other jewellery. Diamonds are mined from the ground, and are then cut, polished, and set by skilled craftsmen. Colourless stones rank the highest in value, with fancy yellow diamonds and rare red diamonds fetching the top prices.  

 

EMERALD

Emeralds are a popular choice as precious gemstones. The name itself comes from the ancient Greek word “smaragdos”, a reference to their green colour. Emeralds are also one of the oldest-known gems on the market, being mentioned in the Bible more than once. Since then, they have been treasured as a symbol of loyalty and love, and have been the centre of many courtly love affairs. The first use of emeralds in jewellery was in ancient Egypt, which assigned them to their goddess Isis, the mother of all living. Emerald gemstones are one of the rarest and most valuable of all coloured diamonds. The beautiful green of an emerald is caused by trace amounts of the element chromium. The finest emeralds come from Colombia.

 

GARNET

Garnet is a small, round red, an orange or yellow gemstone that is often found in nature's minerals. Garnet is available in a wide range of qualities and is the traditional gift for anniversaries. Ravia Jewels offer the finest quality genuine garnet jewellery at the lowest prices. Garnet jewellery is made with the finest materials, such as sterling silver and 14kt gold fill.

 

RUBY

Truly “natural” rubies are rare and highly valuable. Ruby prices are based on four criteria: colour, cut, clarity, and carat weight. Usually, the more intense and saturated the red, the more valuable the ruby. However, the actual colour is a matter of taste. Some people prefer ruby with a less intense red colour.  The value of a ruby is greatly influenced by the cut. The cut is a factor that refers to the proportions and symmetry of the stone. When a ruby’s proportions are balanced and its facets are polished, the stone will have greater brilliance and fire.

 

SAPPHIRE

Derived from the Greek word for blue, this beautiful gemstone is used commonly in a variety of jewellery for men and women. Considered to be the gem of truth, ruby is a marvellous choice to give to one’s loved ones and as a gift on love occasions. It is also the birthstone for September.
