Has anyone used and found it to be a reliable source to identify stones.
I have the filters. Loops. Refractometer and I still have thousands of stones I am.unsure of what they are.
This stone is showing as a spinel with the filters? Does it look like spinel to you all?
Are the filters accurate or should I invest in this machine.
thank you
