The rise of lab-grown diamonds has disrupted the market. Chemically and physically identical to mined diamonds, lab-grown stones sell for a fraction of the price. This has created a downward pressure on the value of lower-to-mid-tier natural diamonds, making them even riskier as a store of value. Where Value Actually Lives

If there is an "investment" side to diamonds, it exists only at the extreme top of the market.

When you buy a diamond from a jeweler, you are paying a significant markup—often 25% to 100%—to cover the store’s overhead, branding, and profit. The moment you walk out of the store, the "resale" value of that stone typically drops by half. Unless you are buying at wholesale prices or investing in rare, "investment-grade" stones, you are starting your investment deep in the red. Liquidity and Standardization No two diamonds are exactly alike.
