The Croghan's Crown Jewels: Rubies, Diamonds, and Sapphires. We wanted to highlight this fabulous trio and share fun facts about these incredible gemstones in our quick guide to gemology. Let the fun begin!
Rubies!
These precious gemstones get their red color from trace amounts of chromium within the stone. The more chromium present in Rubies, the stronger the color!
Color is the most significant factor affecting a ruby's value. Fine rubies are a pure, vibrant red to slightly purplish red.
Diamonds!
Diamonds are formed from immense amounts of pressure underground and pushed to the surface. They are made of pure carbon.
Diamonds are the hardest natural substance on Earth, and the only thing that can cut a diamond is another diamond!
Sapphires!
Sapphires are an extraordinary gemstone coveted for their velvety, deep saturated blue color! Preferred sapphires have strong to vivid color saturation, regardless of hue. Sapphires are a variety of the mineral Corundum, as are rubies. They are the second hardest natural mineral known to mankind.
