You’re very welcome. I remember when I was first learning how to use the refractometer. It was challenging to see the cut off line. Happy to help!

Without that thing , what other test u can destenguish either it is aquamarine or topaz?
@dfhomsydiamonds3 күн бұрын
That's a great question, and with out gemological testing it's very tough! Another gemological tool you can use is the polariscope to figure out the optic figure of the gemstone. Topaz is Biaxial and Aquamarine/Beryl is Uniaxial. Without gemological testing, you can try weighing the gemstones, however it's not a sure fire way of knowing. Topaz Specific gravity is 3.5 to 3.57 and Aquamarine is2.67 to 2.84.

Can you use it with set stones or only loose ?
@dfhomsydiamonds5 ай бұрын
Yes, you can use this refractometer with set gemstones.

says "solution" as if costs nothing. It's expensive as hell.
@dfhomsydiamonds22 күн бұрын
Yeah, Unfortunately it's super expensive. Gemological equipment can get expensive. I did find a place that sells it for a little less though! Thank you so much for watching my video. www.aajewelry.com/ri-liquid.html

Do a polished carbonado black diamond has a refraction?
@dfhomsydiamonds2 ай бұрын
Unfortunately, diamonds cannot be tested on the refractometer. They are OTL (over the limit) The limit is 1.81, and diamond RI's are about 2.42.

@@dfhomsydiamonds what other test can be done to get the refraction of a diamond? Thanks 😊

What liquid is used, and is it replaceable or substituted?
@dfhomsydiamonds5 ай бұрын
Hello @TheMinerEangineer as far as I know you can only use Refractive Index (RI) liquid on the refractometer. You may purchase both through GIA, or just the RI liquid through a jewelry supply company. Below are the links!

can it identify raw sapphire stones?
@dfhomsydiamonds29 күн бұрын
Great question, thank you for asking! The refractometer is best used on finished and polished gemstones. The surface of a rough gemstone will make it very hard to receive an accurate reading. It's doable, but not recommended and doesn't provided great results. Along with the fact that it will scratching your hemicylinder really badly (not recommended).

Not solution .. it refractive index oil. 1.81

Very true! Thank you, yes it’s not a solution it’s refractive index oil.
