GR 36 This is an Australian blue sapphire we at oftheearthgems faceted at our lapidary after obtaining the rough material from the central QLD gem fields which happens to be one of the largest sources of sapphire for the world. This beautiful blue gem should be gracing the hand of some woman or man lucky enough to have the presence of mind to buy it! I love sapphires and have both jewelry to wear and loose stones which are all about the house to give me enjoyment and pleasure and they last a life time. while the initial cost seems for some to be expensive it is more than made up for in the years of happiness they return to the owner. I speak from personal experience, I have sapphire rings that I made 25 yrs ago and they are as beautiful now as when I first made them. How many other things have you bought that can stand the test of time?
