How Much Are Diamonds Worth? [2023]
By Devin Jones
Asking how much diamonds are worth is like asking how much houses are worth. The house could be a tiny shack in a bad part of town or a mansion with a tennis court, swimming pool, and helicopter pad like this one.
There simply isn't a straight answer without more context.
Luckily, StoneAlgo tracks daily diamond prices across over 2 million diamonds delivered to us daily by the world's top online jewelers. Based on our aggregated inventory from top-rated online jewelers, natural diamonds can cost anywhere from $203 to $10,000,000+. Lab grown diamonds tend to cost far less, typically 90% less than natural diamonds or more.
