A few people asked about diamonds and gold, specifically for the purpose of using this answer for buying a wedding ring, and for the sake of investment at the same time. In other words, it is preferable to buy a ring which will not lose its value once bought!
Only a highly prized diamond, like a very large stone or an unusual color, will hold its value or become more valuable over time. Since there is so much variability in the four C’s and there is no set unit price that is recognized in worldwide markets, diamonds are valuable but not as valuable as gold.
