Mini Diamond Tester
Overview
Supplier sourcing insights & recommendations
I have analyzed the market trends and identified top suppliers for mini diamond testers.
Market Trends & Insights (2026)
The diamond tester market is rapidly evolving due to the rise of lab-grown diamonds. Standard thermal testers are increasingly being replaced by multi-testers that measure both thermal and electrical conductivity to distinguish moissanite, and UV-based tools for lab-grown identification MasinadiamondsDoamore. Consumer demand is shifting toward portable "tester pens" for personal verification of online jewelry purchases AccioAmazon. However, accuracy remains a key concern, with common "tester pens" often failing to distinguish lab-grown stones from natural ones, leading to a growing professional niche for advanced UV detection equipment CasadoroTiktok.
