Gem push

Gemmology for makers — know what you set

Gem samples on the grading tray — makers who know their stones set better work.

A maker who knows stones buys better, sets smarter, and sells with
authority. Gemmology is not a separate hobby — it is bench craft's quieter
half.

The three facts that matter most

  1. Hardness decides placement — rings take knocks: Mohs 7+ (quartz and
    up) for rings; softer stones to pendants and earrings.
  2. Treatments are normal and normal to disclose — heat, oil, fill.
    Disclosed treatment at a fair price is fine; undisclosed is the scam.
  3. Imitations are material, not morality — CZ and glass are legitimate
    fashion materials when NAMED as such.
