Human beings have coveted and treasured precious metals for thousands of years. Throughout history, human beings were so enamored of precious metals such as gold, silver, platinum, and palladium, that they made them into religious icons, crowns and staffs for royalty, jewelry, eating utensils and coins. The desire to collect and possess jewelry made of precious metals still exists today, especially antique jewelry. In fact, antique jewelry is still so highly valued that it is often used as currency and collateral for loans.
If you inherit or find a piece of antique jewelry with a ruby in it, you may think that it's your lucky day. However, rubies are rarer than diamonds in the world of gemstones. Synthetic rubies have been manufactured since the early 1900's and jewelry set with manufactured rubies was quite popular in the 1920's and 1930's. You may have a genuine vintage ring or necklace, but there is a good chance that the rubies are synthetic or fake.
