Diamonds, as we all know, are one of the most luxurious gemstones and have been treasured for their beauty since ancient times.

Diamonds are thought to represent eternal love and commitment. Therefore, they are most widely used in traditional wedding or engagement rings and other fine jewelry.

It costs a lot to source pure diamonds from the market for jewelry because the majority of the diamonds that are mined are not pure enough to be used as gemstones.

Only 20% of the mined diamonds end up as gemstones in high-end jewelry. The remaining 80%, mainly referred to as rough diamonds, are bought by manufacturers for industrial uses spanning different automotive, hardware, and glassware industries.

The demand for diamonds in the jewels industry is very high compared to its supply, making it even more expensive.

This makes it even more challenging for retailers and jewelry manufacturers to obtain high-quality diamonds from reliable wholesalers at a fraction of the cost of the market.

To make your life tough a tad bit easier, we’ve compiled a comprehensive list of wholesale diamond suppliers and vendors who are not only known to provide the highest quality but also exceed expectations in all aspects of sustainability, ethicality, and exceptional customer service.
