Unvault made selling my jewelry fast and easy. They communicated through out the whole process. I needed to send them a email and got a very quick response. If I decide to sell more jewelry in the future I will definitely be coming back to them. They received my jewelry on a Friday and I had payment sent on Monday. I honestly couldn't believe they got to it that quickly. Most companies take their time I figured it would be a week or more for the entire process I was absolutely amazed at how fast they get it done. Thank you Unvault team.

Excellent experience! Cannot recommend enough.
I was apprehensive to use a relatively new company to sell my jewelry, but Unvault's platform was appealing and I decided to look into it. I took a chance after seeing all of the great reviews and I am so thankful that I did! The process was super simple, the company is incredibly communicative, and my offer was accurate to the AI prediction and extremely fair. I will be a repeat customer.

Simple, Transparent, and Worth It!
I had a great experience using Unvault to sell my wedding ring set and an additional ring. To be honest, I don’t even remember exactly how I found them; it may have been through a Google AI search or Instagram but I’m really grateful that I did.
The process was incredibly simple. I just took pictures of the jewelry, added descriptions based on what I knew (metal type, number of diamonds, etc.), and uploaded an insurance document I had for the rings. Based on that information, they gave me an estimated value right away.
Once I decided to move forward, they sent me a prepaid shipping label. I dropped the package off at FedEx (through my local Walgreens), got a receipt, and the package arrived to them in about two days. Shortly after, they emailed me to confirm they received it and sent a video of the unboxing. I really appreciated this step—they showed everything I sent, weighed the items on a scale, and took measurements. It made the process feel very transparent and trustworthy.
The best part was that the final value actually came in higher than the estimate. My initial estimate was around $900, but after evaluation it came out to about $1,200. There was a $250 service fee that I didn’t fully realize beforehand (I probably should have read the fine print a little more closely), but even after the fee I still received about $1,020, which was more than I expected.
Once I accepted the offer, they sent me a link to enter my bank information, and the money was deposited into my account the next morning. The entire process from submitting my jewelry to receiving payment took less than a week.
I was honestly a little nervous at first about mailing off valuable jewelry to a company I didn’t know, but everything went smoothly. Their communication, transparency, and speed made the experience really positive.
Another reason I was happy with the service is that my engagement ring had lab-grown diamonds, and many places don’t buy those. I had considered selling locally or going to a pawn shop, but I’m confident I got a better value using Unvault. In fact, one of the rings I sold originally cost me $800, and I received about $752 for it—so it held its value really well.
Overall, the process was quick, easy, transparent, and efficient, and I would absolutely recommend Unvault to anyone looking to sell jewelry.
