If we refer to a stone as a diamond, then it is a natural earth mined diamond. For all other stones, if you see the words "Natural" or "Earth mined" in the description, then the stones are natural.
If those words are not present, please assume the stones are manmade as our tester cannot differentiate between the two. For items with stones like turquoise, coral, or lapis, etc. All stones will be natural unless we include the word faux. The item "Vintage Tiffany & Co.
