It eliminates all the unnecessary costs and allows you to buy diamonds up to 50-70% less than retail prices. And the more middlemen are eliminated in the process, the more savings you can pass on to yourself.

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.

Wholesale diamonds are cheaper for a few reasons. First, they are sourced directly from diamond mines or cutting factories, which cuts out the middleman and allows the buyer to save on markup. Second, because they are sold in bulk, wholesalers can offer a discount on the per-carat price.

Loose diamonds aren't necessarily cheaper than their mounted equivalent, however, they have the advantage of offering buyers a 'complete view' – no inclusions hidden by prongs or color concealment against a setting. Buying a loose diamond online will be considerably cheaper than buying from a store.
