Guide concerning semi gemstones

As we know with, the human being, from its existence, has always really felt devotion and endowed with a certain necromancy to priceless or weird rocks or stones extremely tough to find in nature, providing different uses: for embellishment, as a sign of power and also exclusivity, associated with the cult of particular deities and even using them to recover or otherwise.

Precious stones and semi jewels are, nearly in their bulk, minerals; several of them, nevertheless, are natural.

Gemstones

To compare precious stones and also semiprecious rocks, three factors are used:

1. Its elegance and excellence. When we talk about the beauty and also excellence of a stone, whether priceless or semiprecious, we describe its colour, brightness, transparency and pureness. A pure gemstone, without imperfections and also with a radiant colour, can have an also higher value than a diamond with comparable qualities.

The only three stones or gems taken into consideration precious-in addition to diamond-for the above factors is ruby, emerald, white sapphire and blue sapphire.

RUBY

To consider that only between 1% as well as 5% of the rubies removed from nature are picked for use in jewelry.

EMERALD GREEN

His name comes from Persian; its meaning is "environment-friendly stone".

The emerald stones to buy have actually constantly been extremely valued, since, in spite of the presence of various other environment-friendly rocks, the only crystal was emerald.

A crucial aspect to take into consideration is the treatments that are made to natural gems. The most usual therapies are:

heating, coloring and loading of fissures. These therapies improve the optical residential or commercial properties as well as are admitted. It is necessary that this is specified and also pointed out considering that in some cases the value of a gem adjustments considerably when treated.

One more essential idea is the existence of additions. All-natural gems like synthetic opal have dental caries that house incorporations that can be various other minerals, liquids or gases.

Nevertheless we have to take care to make distinctions in between some artificial rocks that are truly changes in research laboratories yet that result with such perfect qualities that are thought about genuine treasures and also not a straightforward synthetic rock, to provide it a name.
