Buying Guide: Gold, Silver, Platinum, and Diamond Testing And Care
What should you consider when selecting jewelry testing tools? Here are practical questions and answers to guide your decision.
- Do you need an all-in-one solution or a modular approach? If you want convenience, choose an all-in-one tester like the Purity Testing Kit or Gemtone kit. For targeted testing, a dedicated touchstone or scale can be better.
- Is safety and jewelry integrity a priority? Look for authentic touchstones and safe testing surfaces, plus clear instructions to prevent accidental damage.
- Will you test at home or in a shop? Portable kits are ideal for on-the-go testing, while more comprehensive setups suit a home or small business workspace.
- Do you want built-in measurement for precise appraisals? A digital scale with multiple units helps when you need exact weight correlations for gemstones and metals.
- What about cleaning and maintenance? Pair testing tools with a jewelry cleaner to maintain luster between tests and ensure accurate readings.
Practical tips for buyers
- Always follow the manufacturer’s instructions to interpret test results correctly.

FAQ
- What is the purpose of a touchstone? A touchstone helps determine karat and authenticity by rubbing the metal against a stone and comparing the resulting streaks with reference materials.
