Seller Claim Checklist

Use this checklist to separate what a listing shows from what the seller asserts. A clear listing should name the material, disclose relevant treatments or imitations, and provide photographs that let you inspect the actual item or a clearly identified example.

Check the listing

Record the claim before judging the stone

  1. 01

    Write down the exact material name

    Note whether the seller names a mineral, a trade name, or only a color. Descriptive wording such as “blue crystal” is not a material identification.

  2. 02

    Look for treatment and material disclosure

    Check for terms such as dyed, heated, coated, stabilized, reconstructed, synthetic, glass, or resin. If the wording is absent or vague, ask directly.

  3. 03

    Confirm what the photographs represent

    Determine whether the images show the exact item, one sample from a batch, or a general example. Request neutral-light views of multiple sides when the distinction affects your decision.

  4. 04

    Compare the description with visible features

    Check color distribution, clarity, luster, texture, inclusions, chips, polish, and fracture patterns. Treat mismatches as questions, not automatic proof of deception.

  5. 05

    Ask what supports origin or authenticity claims

    A confident label, rarity statement, or claimed location is still a seller claim unless supporting evidence is supplied. Decide whether that evidence matters enough to delay the purchase.

Testing threshold

Know where observation stops

Photographs and basic observation can reveal inconsistencies, but they may not separate natural from synthetic material or detect every dye, coating, filling, or other treatment. Color can also shift with lighting, editing, and screen settings. When identity or treatment status materially affects the purchase, request appropriate documentation or seek independent gemological testing.

Use the result

Choose a proportionate next step

Proceed when the description is specific enough for your needs. Ask for clarification when a relevant disclosure is missing. Pause when the price or decision depends on a claim that the available evidence cannot support.
