Online Diamond Buyers vs Local Diamond Buyers

Online diamond buyers have a clear advantage over local buyers. They benefit from access to a large network of contacts in the industry. This allows them to buy a more varied range of diamond goods.

Some online diamond buyers have access to the international diamond markets and have the latest pricing information. This can be crucial in returning the true market value for your diamonds. If an online diamond buyer online also has a physical location, this provides an extra layer of trust.

WP Diamonds specializes in buying diamonds directly from the public. We have unrivaled knowledge of the second hand diamond sector. We are the largest recycled diamond buyer in the US that has a direct consumer sales channel. This gives us the unique ability to give you the best possible prices in the market place.

Assessing Reputable Online Diamond Buyers

We make the selling process fast and easy. We provide honest price quotes and the entire process can take as little as 24 hours.

Speed of Transaction

Reputable diamond buyers should be able to complete transactions rapidly, buying goods in a matter of days. You should be wary of organizations that string out negotiations and offers to customers. Tactics such as this reflect badly on the industry. Wires should take 24-48 hours and should be commissioned immediately.

Access to Good Prices and Distribution

A key ingredient in diamond transactions is the ability of the purchaser to offer top of the market prices. They can only do this if they have access to diamond markets and re-sell the diamonds they buy efficiently.

WP Diamonds is headquartered in the diamond district of Manhattan, New York. We have direct links to the diamond markets in the US through our business to business operations. We sell our diamonds back into the market, achieving top of the market prices which we pass on to our customers. The New York markets are highly liquid and produce the best prices, giving us a unique advantage.


That’s why we use our insurers
and Brinks to transport your diamonds. We provide
you with a free, fully insured FedEx overnight label
and open your packages on video to make sure that
your diamonds, and you, are protected.
