Gemstones, facts and information.


Our gems, our jewels! Here is a laydown on the nature of some of the gems available with us in the form of exotic pieces of jewellery.
Amethyst is a violet variety of quartz. Owing to its extravagant colour, it is prdominantly used as an adornment stone in jewelleries. Amethyst is composed of an irregular superposition of alternate lamellae of right-handed and left-handed quartz. It has been shown that this structure may be due to mechanical stresses.
Amethyst occurs in primary hues from a light pinkish violet to a deep purple. Amethyst may exhibit one or both secondary hues, red and/or blue. The ideal grade is called "Deep Siberian" and has a primary purple hue of around 75–80 percent, 15–20 percent blue and (depending on the light source) red secondary hues.[6]
Traditionally included in the cardinal, or most valuable, gemstones (along with diamond, sapphire, ruby, and emerald), amethyst has lost much of its value due to the discovery of extensive deposits in locations such as Brazil. The highest grade amethyst (called "Deep Russian") is exceptionally rare and therefore its value is dependent on thea demand of collectors when one is found. It is however still orders of magnitude lower than the highest grade sapphires or rubies (sapphire or "pigeon's blood" ruby).
We have exploited the beauty of Amethyst in the form of beautiful adornments like necklaces, rings and bracelets.
No gemstone is more creatively striped by Nature than agate, chalcedony quartz that forms in concentric layers in a wide variety of colours and textures. Each individual agate forms by filling a cavity in host rock. As a result, agate is often found as a round nodule, with concentric bands like the rings of a tree trunk. The bands sometimes look like eyes, fanciful scallops, or even a landscape with trees

Most agates occur as
nodules in volcanic rocks or ancient lavas where they represent cavities originally produced by the disengagement of volatiles in the molten mass which were then filled, wholly or partially, by siliceous matter deposited in regular layers upon the walls. Such agates, when cut transversely, exhibit a succession of parallel lines, often of extreme tenuity, giving a banded appearance to the section. Such stones are known as banded agate, riband agate and striped agate.
Aventurine
Yet another member of the Quartz family, it is most commonly found in royal green color. Besides green, it can also be found in orange, brown, yellow, blue, and gray. Aventurine is characterized by the flecks of mineral inclusions that gives it a sparkly look. It is found in many parts of the world including India, Brazil, and Russia. It is called the ‘lucky talisman’ and is supposed to increase libido, reduce stress, and strengthen blood and muscle tissues.
Aventurine looks its best cabochon and bead shape. Available in many colours and hues, you can fire your imagination to bead stylish adornments of this beautiful stone.

Goldstone
Goldstone with its fine finish when beaded together in a jewellery form looks absolutely stunning. It is a type of glass made with copper or copper salts in the presence of a reducing flame.
The most common form of goldstone gives the illusion of being reddish-brown, although in fact that color comes from the copper crystals and the glass itself is colorless. Some goldstone variants have an intensely-colored glass matrix—usually blue or violet, more rarely green—and a more silvery appearance to the suspended crystals, whose color may be partially masked by the glass or which may be based on different metals than copper.

Bloodstone
There is a belief that the bloodstone was formed from the blood of Christ dripping on the green earth and solidifying. Incidentally, thus mystic stone is green with distinctive red spots that resemble blood, thereby justifying its name. Sometimes yellow and/or other colors of jasper are also present, but these multi-colored gemstones are usually called "fancy jasper".
This attractive chalcedony quartz is also known as heliotrope because in ancient times polished stones were described as reflecting the sun: perhaps the appearance of the gem reminded the ancients of the red setting sun, mirrored in the ocean. The beads of this stone when hand-beaded together looks absolutely beautiful.

In a stark yellow tinge, Citrine belonging to the family of quartz is often mistaken for Topaz. These beautiful gemstone are just meant for adornment. It is any quartz crystal or cluster that is yellow or orange in color. Although often cut as a gemstone, citrine is actually somewhat rare in nature
Like all crystal quartzes, the citrine has a hardness of 7 on the Mohs scale and is thus, to a large extent, insensitive to scratches. It won't immediately take offence at being knocked about either, since its cleavage properties are non-existent. Even if their refractive index is relatively low, the yellow stones have just that mellow, warm tone that seems to have captured the last glow of autumn.

Carnelian, sometimes spelled cornelian, is a red or reddish-brown variant of chalcedony.
Its radiant orange hue has been mesmerizing women folk since Roman times for embellishments.
Carnelian is a 7 on the Mohs scale and has been used for centuries to carve beautiful cameos. It is found in Australia, Brazil, Madagascar, Russia, South Africa, and the USA.

The extremely beautiful rich red coloured stone which you often mistake for Ruby is Garnet. Tagged as one of the most beautiful semi-precious stones, it is the most sought after stone for carving jewelleries for today its royal red and green colours. Furthermore, the world of the garnets is also rich in rarities such as star garnets and stones whose colour changes depending on whether they are seen in daylight or artificial light.

It is true to say that red is the colour most often encountered, but the garnet also exists in various shades of green, a tender to intense yellow, a fiery orange and some fine earth-coloured nuances. The only colour it cannot offer is blue.
Lapis lazuli with its deep blue colour seems to have emerged from the Arabian Nights. This opaque, deep blue gemstone has a grand past. It was among the first gemstones to be worn as jewellery and worked on during the Alexander times.
Lapis lazuli is an opaque rock that mainly consists of diopside and lazurite. It came into being millions of years ago during the metamorphosis of lime to marble. Uncut, Lapis
lazuli is matt and of a deep, dark blue colour, often with golden inclusions and whitish marble veins. The small inclusions with their golden shimmer, which give the stone the magic of a starry sky, are not of gold as people used to think, but of pyrites.
The Moonstone is characterised by an enchanting play of light. Indeed it owes its name to that mysterious shimmer which always looks different when the stone is moved and is known in the trade as 'adularescence'. In earlier times, people believed they could recognise in it the crescent and waning phases of the moon
Moonstones from Sri Lanka, the classical country of origin of the Moonstone shimmer in pale blue on an almost transparent background. Specimens from India feature a nebulous interplay of light and shadow on a background of beige-brown, green, orange or brown. These discreet colours, in connection with the fine shimmer, make the Moonstone is an ideal gemstone for jewellery with a sensual, feminine aura.
