5 Common Gemstones Used In
Jewellery

2. 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.

3. 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.

4. 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.

5. 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.

6. 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.

7. 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.

8. 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.
