The semi jewels have a very various worth among them as well as it is a lot easier to get semiprecious stones of excellent size and purity (clean) than jewels of such qualities.

The oscillation of worth or expense of semi precious gemstones will rely on the same problems that affect the precious stones: firmness, rarity and also charm and also perfection (pureness, color, illumination and also transparency). There are around 130 mineral species cataloged as semiprecious, along with pink topaz and rainbow moonstone.

Let's see below one of the most crucial and those used in precious jewelry.

Ruby

It belongs to the family of corundum -like the sapphire- and also has a firmness of 9 on the Mohs range. It is the hardest rock after the ruby. When drawn out from nature, the ruby has a crude and also disrespectful appearance, once chosen those that are mosting likely to be used in fashion jewelry as well as after being carved, they take on that unique radiant tone that makes them so marvelous. Take into account that only between 1% and 5% of the rubies removed from nature are chosen for use in jewelry.

Purple

As we already know, the amethyst was thought about a jewel, but after the exploration of mines in Brazil, its rarity was shed as well as it became part of the team of semiprecious stones. It is one of the most priced estimate quartz selection out there. Its most valued shade is a lavender violet, however can be yellow and even clear, depending upon the quantity of iron it consists of. His firmness on the Mohs range is 7. In spite of having actually decreased a ladder and also be a semiprecious rock, as a result of its charm and popularity is worthy of that, later on, we create an unique write-up for her.

Citrine

It is another variation of quartz, however of lemon yellow shade and with its exact same range of solidity, 7 Mohs. Its name originates from the French citron.
