The diamond industry's most successful product isn't a diamond. It's a belief.
The belief: that diamonds are rare. That's what justifies the price, the tradition, the idea that a small stone is worth months of salary. It's also, for most diamonds, not quite true.
When large deposits were discovered in South Africa in the 1860s, the people who controlled the mines faced a problem. There were a lot of diamonds. More diamonds than the market expected. More than enough to satisfy demand at reasonable prices - which would have made the prices collapse.
Cecil Rhodes's solution was to consolidate. He bought up competing mines and created De Beers Consolidated Mines in 1888. Instead of competing on price, he restricted supply. Not because there weren't diamonds. But because the price required that there not be too many diamonds.
By the mid-20th century, De Beers controlled a dominant share of the world's rough diamond supply, often estimated at roughly 80-90% at its peak. They stored excess inventory in vaults - actual physical diamonds kept off the market to prevent prices from falling.
This is cartel-like supply control, and it works precisely as designed. The diamonds exist. They're just not all for sale.
The scarcity you feel when you design a diamond ring in our Ring Builder is real in one sense: a diamond at that price is scarce. But that scarcity is partly engineered. The earth produces far more diamonds than are available to buy at current prices.
None of this diminishes a diamond's beauty, its physical properties, or what it means to the person wearing it. But the mystique of rarity - that part was a business decision. If you'd like to understand how we approach diamond quality transparently, our education page explains it plainly.
