Yes, we can ship to Peru. That option should be available to you upon checkout.

Does it come with a warranty?

Yes, the Gem-n-Eye comes with a 1 Year Manufacturer's Warranty. I will add that spec to the product description. Thank you.

Does it give two readings if you change the position of the stone so you can determine birefringence?

The Gem-n-Eye does not measure Birefringence. However, changing the position of the same gem can give a slightly different reading, but that is from the variability in the reflectiveness of the surface of the gem, combined with the ultra-sensitivity of the Gem-n-Eye which offers resolution all the way down to .001 of an Refractive Index. In order to measure Birefringence, you will need a traditional, Critical Angle Refractometer, the kind that requires the RI fluid.

Does it work on cabochans and opaque stones?

Cabochans - no. Opaque stones - yes. The rule is that the stone must have a perfectly flat surface that is highly polished. Thus, almost all faceted gems are measurable.
