Recently I wrote a blog about raw rubies before they are cut, polished and turned into jewelry. Today I’m posting images of the 3 other precious gemstones in the raw. When we visualize gemstones, mostly we see them as the sparklers they become after craftsmen and jewelers get their hands on them like the above Harry Winston diamond ring. Not how them start or grow in nature, but how they are finished, right? So let's look at a few images of gemstones as they are found in nature.
I. Diamonds are a single element. Formula: C. A diamond is an allotrope of the element carbon. Its structure is a rigid three-dimensional lattice where each carbon atom is bonded to four other carbon atoms in a tetrahedral arrangement. A diamond’s atoms are arranged in a crystal structure called a diamond cubic. The gemstone rates a 10 on Mohs Hardness Scale. BTW: graphite, charcoal, and diamond are all allotropes of the element carbon.

III. Sapphires - are a variety of the mineral corundum. Its formula, α-Al2O3 consists of the elements aluminum oxide with trace amounts of iron, titanium, cobalt, lead, chromium, vanadium, magnesium, boron, and silicon. Sapphires register a 9 on Mohs Hardness scale. Blue is the most in demand color. When sapphires are yellow, orange, purple, pink, or green they are called fancy sapphires. When corundrms are red, they are rubies, not sapphires.
Gemstones take millions of years for the Earth to produce, or nowadays they can be grown in a lab, but it takes the artistry of human hands to turn these majestic crystals, beryls, and corundums into gorgeous pieces of jewelry. The next time you see a gemstone think of its journey and how many hands went into crafting it into a thing of beauty.
