This months birth stone is one of the four precious stones, Ruby. The name comes from the Latin word ruber which means red. Natural, untreated rubies come in pinkish red to blood red, the richer the color and lack of thread like inclusions the more valuable. You will find that most natural (untreated) rubies will have inclusions and this distinguishes them from synthetic or simulated (lab created) stones. Now a days a lot of the rubies out there are heat treated to improve color and mend inclusions, so always ask your jeweler!
For centuries the best rubies came from Burma but now have been discovered in Myanmar, Thailand, Cambodia and even Afghanistan.
And as always if you are looking to add rubies to your collection feel free to contact me with any questions at http://www.quinsultants.com.
