Why Gallery Diamond?
At Gallery Diamond, we believe every customer is unique, and every request is an opportunity to exceed expectations. Our dedicated team is committed to delivering exceptional customer service while continuously enhancing our expertise in the world of diamonds and high-end jewelry.
With a passion for craftsmanship, trust, and elegance, we strive to create a memorable experience for each client—strengthening our presence as a distinguished name in the diamond and luxury jewelry industry.
Every GD diamond is carefully inspected by certified gemologists.
Each stone is checked for authenticity, quality, and accurate grading before it reaches our customers.
This strict inspection process ensures that you receive only genuine, high-quality diamonds from GD.
When you purchase a loose diamond or custom-made jewelry from Gallery Diamond, it is shipped along with an official diamond grading report (also known as a diamond certificate). These reports are issued by internationally recognized laboratories such as GIA, HRD, or IGI and are prepared by expert diamond graders.
Since these reports are valuable and cannot be easily replaced, every returned diamond must include its original international diamond report.
In addition to the international report, every Gallery Diamond jewel or diamond is also accompanied by the GD Diamond Report, issued by our in-house gemologists. This report further guarantees the authenticity and quality of your selected diamond.
At GALLERY DIAMOND, integrity is at the heart of everything we do. Every diamond we offer is sourced only from legitimate and ethical suppliers, ensuring they are never associated with conflict or unethical practices and fully comply with United Nations resolutions.
GD guarantees that all its diamonds are 100% conflict-free, based on strict supplier verification, written assurances, and our own professional due diligence.
We proudly follow and uphold the principles of the Kimberley Process, an internationally recognized system designed to prevent conflict diamonds from entering the global diamond trade. This commitment ensures that every GD diamond represents not only beauty and brilliance—but also responsibility and trust.

Already selected a diamond from another supplier?
Before you finalize your purchase, let GALLERY DIAMOND help you discover whether you can get the same quality—or better—at a more competitive price.
With our GD Diamond Comparison Purchasing Service, our expert gemologists compare your chosen diamond against our extensive GD Diamond Inventory to find the closest possible match in quality, brilliance, and value.
How it works:
- Share the diamond details and price offeryou’ve received from another supplier by emailing us at info@gallerydiamond.com.
- Provide as much information as possible about the 4Cs—carat weight, color, clarity, and cut—along with additional details such as fluorescence, measurements, table %, pavilion depth, crown height, and other grading factors.
- The more precise the information, the more accurate and competitive your matching result will be.
- Our GD experts will carefully analyze and respond with a matching or superior diamond option, often at a better price.
You can also speak directly with a GD specialist by calling +44 20 4579 3367 (replace the old phone number everywhere with the right one. Add two companies contact details as you did already in the education section. Use the same motive so it’s familiar to the user from page to page) , and we’ll personally assist you in locating your ideal GD diamond.
