Product Description

This refractometer was developed to test gemstones and solid materials for their refractive index. In the world of gem test instruments, people often think that gem refractometers are the most important. Refractometers are used primarily to measure the angle at which light is bent or refracted through stones.

Compact size, high accuracy, easy to use The refractometer is very accurate and easy to use. The device is convenient to carry since it is a lightweight and compact unit. allows for the identification of gemstones, since it differs from one gemstone to the next. As well as providing information on opaque and transparent gems, the refractor is one of the few instruments that can do so.

The possibility of gems being discovered continues to be eliminated by the values such as R. Low battery consumption and long service life. A description of the colors, hardness, and hardness of the substance. This method is a great tool for separating gemstones because the transparent gemstone is tested and polished flat to a smooth surface.

A quick and accurate way to identify both single gems Provides the ability to identify diamonds, moissanites, and colored gems, helps speed up the identification process, and avoids the need to use RI liquids each time. The display is clearly visible, allowing you to read measurements in a glance.

Questions & Answers

How can the device be used to determine the authenticity of turquoise ?

Well, that's a bit difficult to say. Real turquoise comes from China nowadays, but there is a lot of it out there. If there are no gold flakes, then it might be glass. Just my two cents. *br> *br>I usually determine real turquoise by seeing if it has little gold flakes (which it should) and if it's cold (warmer beads are plastic).

Are laboratory created gemstones identifiable by this device?

The answer is yes. In addition to knowing the refractory index for each gemstone, you must also know the refractory index for lab-created gems. The two are slightly different. For glass, there is only one index - (At least 5). On the Gem Society's website, you can find information on the refractory index. It is a great tool that I have used both naturally and by putting a light source in front of it.

The refraction liquid can be purchased from where?

It is not necessary to use the fluid in mine. Since the fluid is cancerous (according to a dear friend who is a gemologist), I chose the type that does not require It might help if I explain that.

What is the difference between a diamond and a ?

have not tested the device on moissanite, but with diamonds I find it to work well. In tests, I identified a colored gemstone based on their optical properties since many synthetics possess the same properties.

I believe the seller to be dishonest

3/5

Upon receiving the item, I contacted the seller to inform him of the defect. Despite my concerns about a refund, he assured me they would handle it. I received an email from Amazon informing me that the product was their fault. He asked for pictures of the defective product. There is nothing meaningful about the item. You should be careful when you buy!.

Having said that, I would like you to know that you are selling a complete product

3/5

I was unable to test or use the refractometer because there was no refractometer fluid included When this important part is missing from the instrument, you are selling a useless one.
