I had an excellent experience dealing with J.S. Diamonds. The entire process was straightforward and easy. Communication was clear and prompt throughout. Most importantly, I felt I could trust them completely, and they offered the fairest pricing I found after doing my research. I highly recommend J.S. Diamonds. Great service all around.

SIMPLY FANTASTIC! Sal & Jessica (and Lola!) provided the best customer service. In addition to being extremely knowledgeable about the market and the business they conduct, this outstanding team were more than fair when it came to buying the items I brought with me! They took the time to explain to me in a very easy, friendly way how they test for certain materials/metals, the market value of such metals, and pretty much everything I needed to know. I HIGHLY RECOMMEND you come and visit their business right in the heart of Rockefeller Center!

Sell Diamonds Houston FAQs

Where is the best place to sell diamonds in Houston?
Houston offers a range of options for selling diamonds, from private buyers to jewelry stores and professional diamond dealers. However, the most reliable and profitable choice is often a certified buyer who specializes in second-hand or estate diamonds. These professionals can provide accurate appraisals and competitive market-based offers, especially for certified stones.
Do I need to clean my diamond jewelry before selling it?
It’s not required, but cleaning your diamond can improve its appearance and make the evaluation easier. A clean diamond shows its brilliance and flaws more clearly, allowing buyers to make a faster, more accurate assessment. Use a soft brush and warm soapy water, or let the buyer clean it during the appraisal.
Can I sell engagement rings or inherited diamonds in Houston?
Yes, engagement rings, family heirlooms, or estate diamonds can be sold to buyers in Houston. In fact, many buyers specialise in such items. For inherited pieces, it's helpful to bring any original documentation or previous appraisals. If none exist, a qualified buyer will still be able to assess and make a fair offer based on the diamond’s condition and market value.
How do I know if I’m getting a fair price for my diamond?
You can verify this by obtaining multiple quotes from reputable buyers, especially those with gemological training. Compare the evaluations and ask how the offer was calculated. A fair price takes into account the diamond's cut, color, clarity, carat, certification, and resale potential. The most ethical buyers in Houston will break down these factors during your consultation.
What payment methods are used when selling diamonds in Houston?
Most buyers offer immediate payment via cash, check, or wire transfer. For high-value diamonds, bank transfers are typically preferred for security reasons. Always ensure you receive proper documentation of the transaction, including a sales invoice or appraisal summary.
