RUBY FOR SALE
Ruby is a variety of corundum that's distinguished for its bright red color. The colors of this mineral can vary between pinkish-red to a deeper blood-red. It's one of the most popular gemstone for both its alluring color and hardness (9 on Mohs hardness scale), making it suitable for nearly all types of jewelry. The other gem variety of corundum, sapphire, encompasses the remaining colors (mainly blue), while still having the same chemical makeup. For this reason ruby can be classified as red sapphire, but typically is left as its own gemstone variety due to its historical significance and appealing coloration.
