There is no only Corals in stores El Coral

Welcome to the post nº4 of the blog of El Coral, in which we will talk about precious and semiprecious stones.

Our brand name is ‘El Coral’, however, in our shops we have not only corals. We work and sell all kind of stones, too. Our speciality are the semiprecious stones. In this publication of our blog we want to explain a little the differences between precious and semiprecious stones and start to introduce some of them.
Distinction between precious stones and semiprecious stones is fairly recent, considering that it take place at the 19th century.

The most well-known precious stones are, without a doubt, Diamond, Ruby, Sapphire and Esmerald.

On the other hand, the semiprecious stones list would be very long, so we will only mention some: Aquamarine, Amazonite, Aventurine, Citrine, Carnelian, Jasper, Fluorite, Jade, Lapis lazuli, Tiger’s eye, Olivine, Opal, Moonstone, Sodalite, Turquoise, etcetera, etcetera.

Amethyst was classified at first as a precious stone, but its category changes, almost at the same time of this classification’s creation, when a huge deposit of this mineral was discovered in Brazil and Uruguay.

Stones’ preciousness is established by their purity, colour intensity and the difficulty of finding them. When it’s more difficult to find a stone over the world, its preciousness is higher. On the contrary, if the stone is more present in nature, its value is lower, becoming then into semiprecious, as in case of amethyst.
However, distinction between precious and semiprecious stones may cannot be reflected exactly in the same way when it’s time to determine their commercial value. In fact, a precious stone with lowest purity level or with an obvious imperfection can arrive at cost much less comparing it to a semiprecious one whom colour is similar. Likewise, the work of the stone’s cut can provide it with a big commercial value, although the stone is classified as a semiprecious. Weight and size also count to establish each piece’s price, as well as goldsmith’s command who embed them into a jewel can make it more or less valuable, so it not depends only of the used stone kind.
Inside all that speech about distinction between precious and semiprecious stones according to their ability of being found over the world, diamonds deserve another discourse aside. We will talk about this matter on future publications.
