Peridot

The vivid green of the peridot, with just a slight hint of gold, is the ideal gemstone colour to go with that light summer wardrobe. No wonder – since the peridot is the gemstone of the summer month of August.The peridot is one of the few gemstones which come in one colour only. The rich, green colour with the slight tinge of gold is caused by very fine traces of iron. From chemical point  of view, peridot is an iron magnesium silicate. The intensity of the colour depends on the amount of iron actually present.The colour itself can vary over all shades of yellowish green and olive, and even to a brownish green. Peridot is not particularly hard - only 6.5 to 7 on the Mohs scale - but it is easy to look after and fairly robust. Peridot cats eyes and star peridot are particularly rare and precious.

Garnet

It is true to say that red is the colour most often encountered, just is close to the color of the seeds of a pomegranate,but the garnet also exists in various shades of green, a tender to intense yellow, a fiery orange and some fine earth-coloured nuances. its hardness is 7 to 7.5 on the Mohs scale.The only thing they really dont like is being knocked about or subjected to improper heat treatment.

Auquamarine

From the light blue of the sky to the deep blue of the sea, aquamarines shine over an extraordinarily beautiful range of mainly light blue colours. In fact aquamarine is related to the emerald, both belonging to the beryl family. The colour of aquamarine, however, is usually more even than that of the emerald. Much more often than its famous green cousin, aquamarine is almost entirely free of inclusions. Aquamarine has good hardness (7.5 to 8 on the Mohs scale) and a wonderful shine. That hardness makes it very tough and protects it to a large extent from scratches.

Tourmaline

The name tourmaline comes from the Singhalese words tura mali,which means something like stone with mixed colours, referring to the colour spectrum of this gemstone, which outdoes that of all other precious stones. There are tourmalines from red to green and from blue to yellow. They often have two or more colours. There are tourmalines which change their colour when the light changes from daylight to artificial light, and some show the light effect of a cats eye. No two tourmalines are exactly alike. This gemstone has an endless number of faces, and for that reason it suits all moods. No wonder that magical powers have been attributed to it since ancient times. In particular, it is the gemstone of love and of friendship, and is said to render them firm and long-lasting.

 Amethyst

The amethyst is extravagance in violet. A more apt stone for the month of February.It has its hardness (7), its moderate refraction and its weight in common with the other quartzes, but the crystal structure is different, and it is most unconventional.The amethyst changes its colour on being heated. Smoky stones are transformed at temperatures of as little as 250 degrees to a shining yellow to brownish-red, whilst clear ones, i.e. those with a high degree of transparency, become yellow or colourless at 400 degrees.

Turquoise

The best Turquoise quality shows a clear and light sky-blue. The colour is highly appreciated, with or without the fine regular spider web lines. The quality decreases with the increase of green in colour, and the increase of spots and irregularities in the spider web.

Turquoise should be protected from cosmetics, heat and bright daylight. The gemstone does not really appreciate sunbathing. It is recommended to clean it from time to time after wearing with a soft cloth.
The colour of a Turquoise will make you feel happy and relaxed, for it combines the light blue of the sky with the invigorating green of the seas.

Citrine

Citrine is one of the most affordable gemstones, thanks to the durability and availability of this golden quartz, with its colors ranging from yellow to gold to orange brown. The darker, orange colors of citrine, sometimes called Madeira citrine after the color of the wine, has generally been the most valued color.Citrine is generally more inexpensive than amethyst and is also available in a wide range of calibrated sizes and shapes, including very large sizes. Since most citrine on the market started its life as amethyst which was heated to turn its color to gold, citrine jewelry, as well as amethyst jewelry, should be kept away from prolonged exposure to strong light or heat.

Agate

No gemstone is more creatively striped by nature than agate, chalecedony quartz that forms in concentric layers in a wide variety of colors and textures. Each individual agate forms by filling a cavity in host rock. As a result, agate often is found as a round nodule, with concentric bands like the rings of a tree trunk. The bands sometimes look like eyes, sometimes fanciful scallops, or even a landscape with dendrite trees.
