Red Ruby Burma
How to determine ruby source?
I have an old ruby gemstone set in silver ring. The stone was bought by my late father in 1970s. The weight is approximately 5 carats and the stone was cut cabochon. The ruby has a vivid hot pinkish red color, but also a color zoning which the color is softer and got an asterism in there (35% length of the stone). The gemstone is included especially in the softer red-pink zone while at the vivid red zone is much cleaner.
I tested it at the local gem lab, says it doesn't show any signs of treatment. But shame, It also doesn't explain where did this ruby came from. When I look at it with 10x magnifier, I can see tiny cracks all over the ruby. I also tested it with UV light and it burns orangish-red, so maybe it doesn't came from Thailand. Either it's from Myanmar or Africa.
Is it possible for me to find out where did this gemstone came from?
Chances are it came from what was known as Burma, now Myanmar. What you have there is a Star Ruby, which are not common in mining. I worked for a Jewelry manufacturer in the late 70's, most of the parcels back then, came from Burma. The stone you mentioned was quite popular in the late 70's. Also among them were Star Sapphire's. You might want to look further in Corundum mining.
However, I came across this site which might help you in your quest.
