The Leading International Diamond Experts

December 19, 2019 - Diamond Articles
Diamonds are easy to lose, expensive to insure, and difficult for a novice to sell. What to do with the engagement ring from a previous relationship or the diamond jewelry you no longer love? Who can you trust to provide you with an honest price for your loose stones or diamond jewelry?

Get answers to these questions:



Anybody can call themselves an expert. There’s your cousin, who considers herself an expert because she has been engaged a couple of times. Then there’s the professional gemologist who has passed a stringent accreditation examination by the GIA.

Our rundown:

  • Professional Diamond Buyers: Specialist diamond buyers, such as WP Diamonds, are made up of GIA trained gemologists. Our team has the industry knowledge to best evaluate and price diamond jewelry. Because we do a high volume of diamond business, we know the diamond market inside out.

We know which cuts are selling best—as well as which diamonds would benefit from a recutting. We understand how fluorescence impacts the value of a stone. The difference between a GIA report and an AGS.

As professional diamond buyers, we provide a free, streamlined selling process that can take as little as 24 hours. We provide you with the option of selling your engagement ring or diamond ring either online or in person. We believe in providing transparent pricing, honest quotes and an enjoyable selling experience.

  • Jewelers and Pawnbrokers: Along with years of experience in the business, most jewelers and pawnbrokers have some kind of formal training. However, they likely do not do a volume business in buying and selling diamonds. As a result, may not be up to date on diamond market trends.
  • Amateur Diamond Buyers: Thanks to platforms like eBay and Craigslist, there are more amateur diamond buyers than ever before. However sites are only as trustworthy as the people using them.

Beware of scams: buyers who claim your stone is a fake and demand a price reduction. Those who try haggling after the transaction is complete. Or worse, when someone returns your diamond jewelry having swapped out the stone for a fake diamond.

We strongly recommend working with diamond experts who meet the following criteria:

  • Training: The gemologist who evaluates your stone should be GIA trained.
  • Experience: Diamond grading is complex, so look for a business that employs a GIA trained gemologists. Assessing the exact characteristics of a stone and ascertaining current market worth requires pricing expertise as well as technical knowledge.
  • Reputation: Only work with professionals who have an excellent rating with the BBB and plenty of outstanding reviews. Bad reviews or few reviews are an immediate red flag.
  • Safety: Diamonds should be secure, fully insured, and trackable at all times.
  • Convenience: A true expert will provide a seamless and transparent selling process both online or in person.
  • Strong Prices: Established diamond experts should possess the necessary industry connections in order to provide clients with competitive offers.
  • Free Service: Some buyers deduct fees or commissions before paying you. A reputable diamond buyer will offer a free service with no hidden costs.


WP Diamonds was founded in 2012 by industry veterans who recognized a lack of viable options for selling diamonds securely. We believe that the process of selling should be enjoyable as the process of buying. As such, we offer a streamlined, simple, and entirely painless selling process. We pride ourselves on providing not just strong prices, but also a convenient, discreet, and professional process with unparalleled customer service.

Preserve any paperwork: Jewelry from designer brands comes with a presentation box and a certificate. Keep these materials in good condition as they add value.

Diamond Certification: You may have a certificate from a grading lab detailing the diamond’s characteristics. Be aware that some labs are more generous with their valuations than others. GIA certification is considered to be the most accurate and detailed.
