Sell Your Diamonds to Trusted Buyers for Fast Cash

Q: How does the diamond selling process work?

We’ve designed the diamond-selling process to be simple, secure, and discreet. You can schedule an appointment for an in-person or virtual evaluation. If you accept our offer, we’ll issue payment on the same day. For online clients, we provide a fully insured, prepaid shipping label, so you can send in your diamond safely and with peace of mind.

Q: How much money can I get for my diamond?

We offer the highest market value for your diamond, based on factors like carat weight, cut, clarity, color, certification, and overall condition. Payouts range from $2,000 up to $10 million, depending on the specifics of your diamond.

Q: Is it better to sell or pawn a diamond?

Selling your diamond is a great choice if you’re ready to part with the piece permanently and want to maximize your immediate return. However, during times when the diamond market is down, pawning your diamond may be the more advantageous choice. Regardless, at Qollateral, we focus on buying diamonds outright, offering competitive payouts for high-quality stones.

Q: How soon do I get paid after selling my diamond?

Once you accept our offer, payment is processed the same day. You can choose to receive funds via cash, check, or wire transfer, whichever is most convenient for you.

Q: What happens if I don’t accept the offer?

There’s absolutely no obligation to sell. If you decide not to move forward, we’ll return your diamond right away, free of charge and hassle.

Q: How is my diamond stored and protected?

Your diamond is fully insured by Lloyd’s of London and stored in a high-security vault inside the International Gem Tower, one of the country’s most secure locations. Our expert team handles every item with the utmost care and professionalism.

Qollateral is a national leader in diamond purchases. Sell to our experienced team of diamond buyers and get the highest price for your loose diamonds and diamond jewelry, plus the expertise, security, and competitive offers you expect when you sell something so valuable.
