Estate Buying & Liquidations

Are you thinking about selling your diamonds, colored gemstones, jewelry, watches, or precious metals?

Not sure if it makes sense to sell now or later?

Did you inherit these items and are unsure whether you want to keep or sell the items depending upon their value?

Do you want to sell these items but you don’t know who to trust?

We have the solutions to these and many of your other questions. We know that when it comes to selling, it can be stressful situation. We understand the concerns you may have and perhaps an emotional attachment. We want to help you make an informed decision by educating you about what you have. We will never pressure you to sell and everything is confidential. We buy all diamonds, colored gemstones, jewelry, watches, and precious metals. We have unlimited resources to liquidate everything from a single item to an entire estate.

We offer two types of liquidation services.

The first option is an immediate liquidation. We will make you a fair offer the same day and pay you immediately by check.

The second option is an orderly liquidation. You hire us on a commission basis to sell the item for you through our international network of buyers. This option enables us to advertise the items in the world marketplace which may attract additional buyers in a variety of geographical locations and market levels. Items are typically sold within 5 to 120 days depending on market conditions. Once the items are sold and we collect payment from the buyer, you will be paid immediately by check.

We comply with local laws using a scale certified by the Allegheny County Weights and Measurements and a Precious Metals License from the Allegheny County Sheriff.
