    I sent my information and a few photos and heard back from Seth that same night! He gave me a general estimate and I later made an appointment so he could assess in person. Seth was so warm and friendly! The whole experience was great and I felt like I made a new friend by the time I walked out.

    Suzanne Meade

    I needed to sell a diamond solitaire ring, and Seth was able to pay more than two other offers I got locally. The process was surprisingly relaxing and easy. He also helped me find an affordable pair of diamond studs. I have already recommended Seth to a few colleagues and friends.

    Katy Satterthwaite

    It was a pleasure to work with Seth! I found him on Facebook, read his information and decided to make an appointment to sell my mothers estate jewelry. He responded promptly, and was very diligent and courteous in examining all the pieces. He made quite a generous offer! Seth was very friendly and honest to work with. A great experience!

    Types of Diamonds Seth Buys

    Seth buys diamonds in any shape, size, color or cut, from loose diamonds, to diamond engagement rings, to Art Deco diamond tiaras. Here are just some of the items Seth buys in Columbus:

    How Seth Evaluates Your Diamonds

    Seth carefully tests each diamond using state of the art technology, including diamond testers that measure heat and fluorescence to confirm your diamonds are real.

    Visual Inspection

    Seth will closely inspect your diamond jewelry using a jewelry loupe to get a clear view of the cut, clarity, and color. These characteristics, along with the carat size, determine the worth of the diamonds.

    Lab Test (GIA)

    If it helps to determine or increase the value of your diamonds, Seth will send your jewelry or stones to an independent lab (GIA) for certification. This will prove the diamonds’ quality and authenticity.

    Electrical Conductivity

    Seth will use a device to test the electrical conductivity of your stone and determine whether it is a real diamond or moissanite. Diamonds and moissanites conduct electricity differently.

    Market Demand

    Once your diamonds have been appraised, Seth will contact his network of industry buyers to understand how much your diamond is currently worth in the market.

    Discover the 4Cs of Diamonds

    When evaluating your diamonds, Seth looks at the 4Cs: color, clarity, cut, and carat size to arrive at your offer amount.


    The most important of the 4Cs, cut affects how the diamond takes and releases light i.e. it’s sparkle!


    The second most important of the 4Cs is color. The less color, the higher the value. Less is best!


    Clarity refers to the tiny imperfections on the surface and inside the diamond which can affect its beauty and value.


    Carat refers to the diamond’s weight, not its size. Note: a bigger carat doesn’t always equal a higher price.

    How It Works

    Working with Seth is quick and easy. It’s just 3 simple steps.

    1. Send Photos & Descriptions

    Text, submit, or email photos, descriptions, certificates, receipts and any other info you have about your diamonds to get a valuation range.

    2. Meet or Ship Your Items

    Show your diamonds to Seth in person, either at his office in Old Worthington or your home/office/bank vault, OR ship them for FREE via FedEx.

    3. Get Your Valuation & Offer

    Once Seth has inspected your items, you will receive a FREE market valuation and a zero obligation offer. If you’d like to sell, Seth will write you a check on the spot.
