The semi gemstones have a really different worth amongst them as well as it is much easier to get semiprecious stones of fantastic size and also pureness (clean) than gemstones of such features.

The oscillation of value or expense of semi precious gemstones will depend upon the very same conditions that affect the precious stones: solidity, rarity and elegance and excellence (pureness, shade, brightness as well as openness). There are roughly 130 mineral species cataloged as semiprecious, in addition to pink topaz and also rainbow moonstone.

Let's see below the most essential and those used in precious jewelry.

Ruby

Key characteristic of the ruby gemstone is the intense as well as brilliant red shade that its own name suggests. This color is because of the steels that compose it, iron as well as chromium. It belongs to the household of corundum -like the sapphire- and also has a hardness of 9 on the Mohs range. It is the hardest stone after the diamond. When removed from nature, the ruby has a coarse as well as disrespectful appearance, once picked those that are mosting likely to be made use of in precious jewelry and also after being sculpted, they take on that unique radiant tone that makes them so magnificent. Consider that just in between 1% and also 5% of the rubies extracted from nature are chosen for use in jewelry.

Agate

It can have several shades and colors - relying on the formation of its silica microcrystals (quartz) - as well as be clear, translucent or nontransparent.

The formation of the agates is due to the blood circulation of underground waters that remain in closeness to the silicon saturations, to the filling of the tooth cavities or indoor openings of the rocks as well as the dissolution of the materials that are there: coverings, bones, and so on. This process is because of the particular concentric bands of the agates, which advise us of the knots of the trunks of trees. The term agate originates from the Greek "Achates", which is the designation of the river with the very same name. His solidity on the Mohs scale is 7.

Aquamarine

Actually it is a version of it, yet light greenish blue. As the name recommends, its shade as well as illumination reminds us of sea water. Its name originates from the Latin aqua marina, as well as previously it was additionally known as the seafarer's rock.

Amethyst

As we currently recognize, the amethyst was thought about a precious stone, yet after the discovery of mines in Brazil, its rarity was shed as well as it entered into the team of semiprecious stones. It is the most quoted quartz variety in the marketplace. Its most valued color is a lilac violet, but can be yellow and also even transparent, depending upon the quantity of iron it includes. His hardness on the Mohs range is 7. Regardless of having gone down a ladder as well as be a semiprecious rock, because of its elegance and popularity is worthy of that, later, we create an unique write-up for her.

Citrine

It is another version of quartz, yet of lemon yellow color and also with its exact same scale of hardness, 7 Mohs. Its name originates from the French citron. Formerly, it had come to be called "quartz topaz" as a result of its resemblance to topaz, however we should make it clear that they are 2 totally different stones.
