The seller claims these are 100% natural rubies. That alone is a rather bold statement, taking into account that most of the rubies on the market are heated nowadays.
Take a closer look and you will notice small bubbles within these rubies. These are gas bubbles that are present only in lead glass-filled rubies (also known as composite rubies). Composite rubies have serious durability problems and are extremely cheap.
Alike rings cost around $30 – $50. Thus, the expert’s estimate is an extreme exaggeration.
Don’t fall for this scam!
