Jewels and gems last a while, therefore smart sales folks can make claims like this can be an “investments” and “will invariably be worth more than what they value”. But that assumes the goods rise in value and you can easily sell them with low sale costs. Demand and offer is everything.

Antique vintage jewelry historically appreciate at about the rate cash inflates; in the words of Dave Atlas – “Most luxury things we purchase wear out or rot”. Jewelry, and especially diamonds, can last forever and have more “intrinsic price” than cars and houses. Land has “Intrinsic price” and therefore too do gold and diamonds. But the “fashion price” can be fickle, unless the piece is a rare collectable.

To sell the most important drawback about investing in diamonds is finding a buyer, one who shares your style and wants to shop for what you would like to sell right now.
