SAM multi-tester

Summary

This is the absolute-best multi-tester for non-diamond / diamond / Moissanite

• this is the only tester that works on the new (low-conductivity) Moissanites that show up as 'diamond' on most testers (and there is no UV light to help with "difficult" stones - it just works!)
• fastest response time (test-result in 1 second)
• left-handed or right-handed use
• thinnest probe (0.45mm) tests stones as small as 0.01 carat (1 point)
• can be used with batteries or USB power
• in its case it's smaller an neater than other diamond testers.
• one year guarantee

See our Guide to buying diamond testers.

RELIABIILTY

I haven't tested thousands of stones but I estimate that this tester will give the correct result close to 100% of the time (97%? 98%?) - there is no tester in existence that is 100%.

Developed a fault in the guarantee period (1 year): new item, not enough sold to know.
