Rubellite Tourmaline

Tourmaline is a crystal boron silicate mineral compounded with elements such as aluminium, iron, magnesium, sodium, lithium, or potassium.

The tourmaline mineral group is chemically one of the most complicated groups of silicate minerals. Tourmaline comes in a wide variety of colours.
There are red and pink tourmalines in many varieties, however, only a very few of these are entitled to call themselves 'rubellites'. The name comes from the Latin 'rubellus', which means reddish. Rubellites are not merely red or vivid pink tourmalines. There is an important criterion. Many gemstones change their colour depending on the light source. A true rubellite does not. It shines just as intensely in artificial light as it does in daylight. The colour of most other pink or red tourmalines, by contrast, displays a visible touch of brown in artificial light.
Rubellites are found in abundance in Brazil, Mozambique, Nigeria, Madagascar and Pakistan. There is also a rubellite mine in the USA. Today rubellite tourmaline is one of the most popular semi-precious gemstones available.

A large portion of rubellite tourmaline gemstones in the market have been treated through heating and irradiation.

New Ethiopian Opal looks like the ocean

The arrival of a new opal from the Welo district of Ethiopia is taking the gem world by storm.

Found in late 2013 in the Welo Amhara Regional State Highland plateau 2,500 – 3,200 meters above sea level, the newly discovered opal gem stone is quickly gaining attention thanks to its interior resembling an under water scene.
The brilliant colours rival any other top grade opal in the world. Most Welo Opals have a brightness level of at least 4 to 5, with hot neon multi-color and multiple pattern mix.

Along with diamonds, emeralds, sapphires and rubies, opal has long been regarded as the fifth precious gemstone.

Spinel of Mahenge, Tanzania

Spinel is magnesium aluminum oxide with the formula MgAl2O4. The name "spinel" comes from either the Latin word "spina" meaning "thorn", due to its characteristic octahedral crystals having pointed ends, or the Greek word "spintharis" meaning "spark".

Although spinel occurs in a range of different colors, the pink to red variety is the one that is commercially important.
Historically, the most famous red spinels came from the Balas region of Afghanistan and were known as Balas rubies. Some of the most famous large rubies in the world, such as the Black Prince's Ruby, part of the British Crown Jewels, are actually spinels. More recently, Sri Lanka and Burma has been the main source for fine spinel. The highest quality transparent blood-red "ruby spinel" and hot-pink spinel has come from the Pein Pyit (Painpyit), Bawpadan, Inn Gaung Pyant and Pingutaung mines in Mogok, Upper Burma.

In 2007 several huge spinel crystals were discovered at Ipanko, near the town of Mahenge, in Tanzania. Miners unearthed several large spinel crystals weighing from six to 54 kg.
Though miners have‬‬ searched extensively in the Mahenge area for more of this rare material, this appears to be a one time find. This is not unusual for fine gems. It happened with Kashmir sapphire and Brazilian paraiba tourmaline.

Since the Mahenge spinel is still a recent discovery, there is still top quality material available for collectors.
Spinel is single refractive and doesn't have pleochroism. It belongs to the cubic crystal system with hardness of 8.0 on the Mohs scale. Spinel offers a range of hues from orange to intense red, vibrant pink, and all shades between purple, blue and violet through to bluish green.
The Imperial Crown of Russia, also known as the Great Imperial Crown, was made for the Empress Catherine II the Great's Coronation in 1762. The crown is set with around 5000 diamonds from India arranged in a pattern of laurel wreaths and oak branches and a number of fine large white pearls. It is topped with one of the seven historic stones of the Russia's Diamond Collection - a large precious red spinel weighing 398.72 carats. The Imperial Crown of Russia is currently on display in the Moscow Kremlin Armoury State Diamond Fund.
