Natural Diamonds Have Undeniable Value Interestingly, all-natural diamonds in the market today are one-fourth to three-fourths the age of the planet. Their age, rarity, and extreme hardness combined with exceptional clarity explain their high value and expensive price tags.

Are diamond prices rising or falling? Over the past year, natural diamond prices have fallen by 24.13% to an average price of about $4,000 for 1 carat natural diamonds.

Dubai is deemed as one of the cheapest places to buy diamonds and rightly so. There's a reason that it is regarded as one of the world's top three diamond trading centers—the other two being India and Belgium.

Natural diamonds cost more than lab created diamonds, but they also hold a unique value that impacts their resale price, giving them higher resale values than lab diamonds. Lab made diamonds do not hold this rarity value, so their initial purchase price and resale values are lower than those of natural diamonds.
