Useful Links And General Resources For Consumers

web resources for diamonds

A diamond engagement ring is a symbol of love and eternity.

Whether you are shopping for a diamond ring via online sources or a physical store, I recommend doing your due diligence beforehand. From experience, this would yield better outcomes and result in a better shopping experience.

Below, I’ve compiled a list of links and resources that will help you research and find out more information before making a purchase.

Where to Verify And Check Diamond Grading Reports

GIA report verification – Simply plug in the report number and carat weight of the diamond at GIA’s official site to check the authenticity of the lab report. It’s also a good idea to look out for the date that the report was performed. Ideally, you want it to be recent and not out-dated by more than 2 years.

AGS report verification – The American Gem Society Laboratories allows you to check and verify information from your AGS grading report against its online database. This service is only valid for documents dated after 1st Jan 2011.

HRD report check – The HRD lab is very popular in Europe when it comes to diamond grading. If you are considering to buy a HRD graded diamond, you might want to key in the certificate number and carat weight of the stone to check the authenticity of your report here.

IGI online report retrieval – To verify your IGI report against the online database, check out this link. Note that this service is only available for lab reports published after June 2004.

GCAL (Gem Certification and Assurance Lab) – One of the smaller scale labs in the industry. GCAL grades a number of lab created diamonds and their reports can offer some insights into the diamond’s performance.

EGL USA online report verification – While I generally don’t recommend people to buy EGL graded stones due to their lax grading system, EGL USA does have a stricter grading process than their “EGL International” counterparts. Use this link to check your reports issued after October 2001.

If you are searching for an ideal cut diamond with awesome light performance, I recommend checking out Whiteflash and Brian Gavin. Their signature diamonds are cut to extreme precision and display superlative brilliance.

Trade Organizations

Jewelers Board of Trade – Not sure whether you can trust a jeweler? The JBoT is an organization dedicated to checking creditworthiness of a business and reviews various aspects of a jeweler’s business for good practices. Get more details there…

Better Business Bureau – Use the BBB to check on the jeweler you are dealing with. Very often, you can tell if they are someone you can trust and do business with based on their BBB page. If the BBB page of a jeweler is filled with many negative complaints, it is a good sign for you to run towards the door and choose another jeweler.

Polygon – One of the world’s leading business-to-business (B2B) trading community for professionals in the gem and jewelry industry.

National Association of Jewellers – The NAJ is a membership consisting of more than two thousand companies. It shapes the British jewelry industry and requires members to act with honesty, integrity and professionalism.
