Photos can help you assess a crystal, but they cannot establish every material identity or treatment. A sensible authenticity check starts with clear descriptions, honest disclosures and questions appropriate to the value of the piece.
A little guidance from Jill
Know what to ask before buying
Join Jill to learn what photographs can show, which questions to ask a seller and when a professional assessment may help.
About 1 min
Watch on YouTube (opens in a new tab)Ask what the material actually is
Request the stated material name and ask whether the seller knows of treatments or manufactured components. Natural stone, laboratory-grown material, carved glass and composite products are different descriptions. An appealing trade name should not replace a clear explanation when composition matters.
Use photos for what they show
Look at colour, pattern, transparency, edges and visible surface features. Inclusions and irregularities are useful observations, but they are not proof that a piece is natural or untreated. A convincing photograph also cannot guarantee that a stone is rare or valuable.
Read the listing carefully
Compare the selected variant with the image and check whether it is an exact-piece or assorted listing. Moss agate slabs, petrified wood and geodes provide examples of how individual patterns can differ. Those examples are not a certification of authenticity.
Avoid damaging home tests
Burning, scratching, dropping or soaking a piece can damage it and still leave you with an uncertain answer. Online rules about temperature, bubbles or colour are not universal identification methods. Ask questions before trying an irreversible test.
Know when to seek testing
For a high-value purchase, unclear identity or an important treatment question, a qualified gemologist or suitable laboratory can provide an assessment. GIA describes using microscopic examination and analytical testing to identify gem materials and detect treatments.
Buy with expectations supported by the information available. If you want to understand a Crystalier listing more clearly, contact us before ordering. We can explain the product description without presenting photographs as a laboratory report.
