Is this 4 carat diamond certified?

Yes. Every 4 carat diamond we offer comes with a detailed certification from a reputable gemological lab. The grading report confirms the quality and specifications of the stone, providing full transparency about cut, color, clarity, carat, and other details.

Which lab certifies 4 carat diamonds?

Although several diamond grading labs certify 4 carat diamonds, we exclusively work with GIA (Gemological Institute of America) and IGI (International Gemological Institute)—both respected worldwide for their accuracy and consistency. Certification from these labs adds both credibility and long-term value to your diamond purchase.

What is the price per carat? How does it compare to the market?

The price per carat rises exponentially at this carat weight compared to others due to rarity and demand. Each diamond is priced based on its individual characteristics like shape, cut quality, color, and clarity. However, we still aim to offer competitive pricing compared to other retailers. Fascinating Diamonds offers a price matching guarantee. To put it in simple words we can beat the price of any retailer by offering our customers the same/similar diamond at a better price.

Can I see the diamond in person or via video call?

Yes. We offer high-definition videos for all listed diamonds. You can also email us to schedule a virtual consultation, allowing for a close-up view of your selected diamond. If you would like to schedule a private, in-person appointment at our showroom to view the diamond under proper lighting conditions, please email us at [email protected]

What is your return, resale, or upgrade policy?

At Fascinating Diamonds, we offer a 30-day return window on all our loose diamonds. All GIA- and IGI-graded colorless diamonds are also eligible for an upgrade program. You’ll receive 100% of the original purchase price as credit toward a new diamond that’s at least twice the value. While upgrades are typically like-for-like (natural to natural, lab to lab), we may accommodate cross-type upgrades on a case-by-case basis. We don’t accept upgrade requests for diamonds purchased from other jewelers.

How long has Fascinating Diamonds been in business?

Fascinating Diamonds has proudly served clients since 2006, offering handcrafted designs, ethically sourced diamonds, and expert guidance. Our reputation is built on quality, trust, and long-term client relationships.

Does Fascinating Diamonds have a physical showroom or office I can visit?

Yes. Our showroom is located in New York City’s Diamond District in Midtown Manhattan, where we meet clients by appointment. Whether you're local or traveling to New York, our gem specialists are happy to host you for a personalized viewing experience.
