antique Diamond brooch

sell your diamond jewelry

People sell diamonds for a variety of reasons. Maybe you want to upgrade your diamond or perhaps you want to get rid of an old engagement ring. Whatever your reason, bring your diamond to Austin Jewelry & Diamond Buyers for an unbeatable offer. 

Our buyer received his credentials from the Gemological Institute of America (GIA) which sets the gold standard of diamond grading. You can rest assured that your diamond will always be evaluated by a well trained eye active in the diamond market. 

We purchase natural diamonds. We are particularly interested in large diamonds over 1.5 carats and antique diamond cuts such as Old Mine Cuts, Old European Cuts, and Antique Cushion Cuts. 

We also buy diamond jewelry including diamond rings, tennis bracelets, and diamond studs. We are always interested in Art Deco diamond bracelets, diamond necklaces, and large diamond rings. 

A lab report on your diamond is not required. However, a GIA report can be a useful aid in our evaluation of your diamond. If you have a GIA report, please bring it with you.

If your diamond was graded by another lab, such as IGI or EGL, it is important to note that these labs grade 1-2 grades higher than GIA. We follow GIA’s standard of diamond grading. 

Selling your diamond can be difficult for many reasons. We understand this, and that’s why your experience with us will always be without pressure or hassle. We guarantee we will always be honest with you and treat you with kindness.


Our goal is that every person who walks through our door becomes a repeat client. We’re committed to providing you with excellent customer service. Building a strong, trusting relationship with our clients is incredibly important to us. We know there are many places to sell your jewelry in Austin, so we want you to feel confident that you made the right choice.


Every time you sell to us, we walk you through our evaluation of your jewelry step by step. We do this so that you understand how we make your offer. We also offer immediate payment upon your sale and will match or beat any legitimate offers you receive. 

how it works

Make an Appointment

Part of what makes us different is that we offer private appointments for all of our clients. This way we can offer you an unparalleled level of customer service and attentiveness.


During your appointment with Jack, he will carefully assess your items and make you an offer for each individual item or as a lot depending on your preference. In most cases, we do not use invasive testing methods.

Get Paid or Trade

We will then write you a check which you can deposit same day. If you'd like to make a trade, we will apply the value of your items to your new purchase.
