National Jewelers Supplies

I love these guys for all my gold testing supplies. They carry items the other guys don't. I bought a diamond tester and it has it saved me more than once the cost of the tester. Great place to buy from!

Bad customer service.
Called to find out about gold testing equipment. They didn't know how it worked. Told me it was not returable if I had a problem.
BAD!!!

I have dealt with many times and you will not find lower prices anywhere. They are great to work with and always happy to help find the right tool. I set up a new store using National and I saved a ton.
