Precious stones have been popular with the human race for centuries.

All gemstones are special to the people who own them. They sparkle and shine and many of them have special sentimental value because they have been inherited from a loved one or received as a gift. Some gemstones are regarded as extra special due their rarity, clarity or colour. They are some of the most expensive precious stones in the world.

Taaffeite
Taaffeite is the only precious stone that was originally identified after it has already been cut and polished. Richard Taaffe, a gemologist, found the stone in Dublin in 1945. It had originally been identified as a spinel stone but Taaffe noticed that the stone refracted light in a different way to spinel. This led to the realisation that the stone was actually a previously undiscovered gem. Even today taaffeite is very rare. The pale violet gem that is virtually transparent is only found in areas of Tanzania and Sri Lanka and many deposits cannot be retrieved so stones that can be cut and polished are not often available.

Demantoid Garnet
The brilliance of these green precious stones is often greater than that of diamonds. Originally discovered by Nils Gustaf Nordenskiöld, in nineteenth century Russia, the stone is mostly found in antique pieces of jewellery due to its high level of rarity. Any demantoid garnets that do exist are usually less than ten carats as the stones are not large in size.

Red Beryl
Although these precious stones are often referred to as red emeralds they are not part of the emerald family of stones. The red beryl is actually a very rare gem that is 8,000 times harder to find than a ruby. It has only ever been found in the Wah Wah Mountains in Utah. The shades of this beautiful stone vary from brighter red to a dark purplish shade. It’s an ideal stone for use in jewellery settings but is most often found in mineral collections as it’s so rare.

Jadeite
Jade is a popular stone in jewellery collections; jadeite is the most expensive version of this precious stone. The stone is most associated with a deep green shade and a translucent state. It can also be found in shades including lavender and mauve. Jadeite is historically popular for use in the weapons and carvings of cultures such as Mayan and Maori. It’s a popular precious stone for use in jewellery settings due to its durability. Stones that have a strong depth of colour and a high level of translucency are the most sought after.

Rarity, size, and uniqueness are just a few of the factors that drive the value of gemstones

Coloured diamonds 
As the song days “Diamonds are a girl’s best friend”. These gems are hugely popular for use in rings and necklaces across the world. Coloured diamonds are the rarest and most expensive form of this gem. Colours vary greatly and include chocolate, green, yellow, blue and red. The red diamond is the most expensive type of diamond in the world due to its rarity. It’s estimated that there are no more than thirty red diamonds in existence and most of them are no more than half a carat in weight.

 

Alexandrite 
Alexandrite is a perfect precious stone to have in a jewellery setting but it’s a very difficult to find. The properties which make it an ideal jewellery stone include its hardness and its variance in colour tones. Look at this precious stone in natural light and it has a greenish blue tone. This changes to a purplish red shade when the stone is viewed in artificial light.

 

These precious stone are amongst the most expensive in the world. They are stones that anyone would love to have set in a piece of jewellery, but they are not always easy to find. It’s this combination of rarity and beauty that makes them so special and so expensive.
