I was walking into our town centre here in Birmingham UK and came across a Gemstone stall, where few stones just grab my attention and that's where this thought came to post this on steemit, Would list few of them today and if my friends and readers would like to know more will definitely be posting more about it.
Amethyst:
Amethyst is the purple colour variety of quartz. It is the most popular purple gem and one of the most popular gemstones of all time. Amethyst is used to produce faceted stones, cabochons, beads, tumbled stones, and many other items for jewellery and ornamental use.
Amethyst has a Mohs hardness of 7 and does not break by cleavage. It is a gem that is durable enough for use in rings, earrings, pendants, bracelets and other types of jewelry. Enormous deposits of amethyst in South America and Africa provide enough material to keep amethyst’s price low enough that most people can easily afford it.
Ruby & Sapphire:
Most of the time people don't realize that ruby and sapphire are both gems of the mineral corundum. Both of these gemstones have the same chemical composition and the same mineral structure. Trace amounts of impurities determine if a gem corundum will be a brilliant red ruby or a beautiful blue sapphire. It is surprising that "impurities" can produce such wonderful results!
Red and blue are just two of the many colors found in gem corundums. Trace amounts of other elements can produce brilliant yellow, orange, green, and purple gems. Red corundums are known as "rubies," blue corundums are known as "sapphires," and corundums of any other color are known as "fancy sapphires." Corundum produces gems in a spectrum of colors.
