Thanks for sharing a very nice and detailed video on the portable polariscope. Here I share a video link of the other type of polariscope, which is called the bench (table) polariscope. here is the link kzfaq.info/get/bejne/e91dm6SL3tG9dXU.html

Is diffused sapphire are effective than glass filled?

at minute 6:31 ...turn the gemstone 360 degrees. I'm flumoxed. As a pilot we tease others telling stories about running into thunderstorms and turning 360 degrees to get the heck out of there. Maybe 180 degress would be what's wanted here too. And I am thankful for the presentation.

An Awesome Informative video. Thanks. Australia. 🇦🇺

Super ❤❤

Fantastic lecture, full of useful information. 'Garnety' is a great word 😂

It was the minerals exhibit in the dark room with the black light that still drives my interest in gemstones, real or synthetic, that change colors under different types of light, from Alexandrite to Zultanite. I make fashion jewelry as well as fine jewelry.

Will glass filled or Flux healed Ruby still shown as Ruby under the Gem Tester II? Thx

I am very grateful this popped up in my feed today! I buy my sapphires from a company in Thailand and when i was looking for my first Padparadscha sapphire, i was following a definition from a gemologist that the intensity should be light to medium. The BE Heated stones were very intense and they were all exactly the same color. They looked fake, or too good to be true, to me, so i chose one with just basic heating. I am now glad i did.

Why is it called star of Ruby India. Is it generated from India?

I learned a lot! Thank you so very much!

Julia, I am jealous. My husband just simply loves everything about you from your hair and voice to your knowledge about this stuff.

Thank you for your lecture on this subject. I would like to be able to do this at home. lol

I like man made stones and frequently buy them instead of more expensive all natural stones. I only care about how the gem presents, Of course now, after watching this, I will suspect all Jewelers . thanks

I had to chuckle when she felt the need to correct herself just for using the term "Man."

Tiger Eye can also be red and magnetic due to the presence of iron.

The distinction between natural and synthetic gems primarily hinges on perceptions of value that are somewhat illusory. A high-quality lab-grown ruby, for instance, created using the flux method, will typically surpass its natural counterpart in terms of crystal symmetry, color consistency, and the absence of structurally significant inclusions. Conversely, it is unlikely for anyone to admire a natural ruby with a large feather that breaks the surface of the table and express appreciation for what they might perceive as a charming flaw. These imperfections are not delightful natural signatures; they are defects, and aficionados of jewelry should not have to tolerate them. In this context, the valuation of natural gems is upheld in a manner akin to cryptocurrency. Once a critical mass of individuals comes to recognize that the advantages of synthetic gems outweigh those of natural ones in every aspect except for a fortuitous perception of rarity, the value of natural gems could plummet, akin to any investment predicated on erroneous beliefs. The fur market serves as an apt illustration of this phenomenon.

I'm sorry. Does Casio still produce watches?

I would like additional information. Gem mining most of the ruby fracture needs to be filled with glass or other compounds to facilitate grinding. Glass that can be filled with ruby divided according to chemical composition, there are several types as follows: 1. Soda-lime glass 2. Borosilicate glass 3. Lead glass or crystal glass This type of glass has more than 24% lead oxide and has a high refractive index. 4. Opal glass 5. Aluminosilicate glass 6.Alkaline-Earth Alumino silicate 7. Glass-Ceramics 8. Crown glass 9. Flint glass 10. Bismuth glass Because lead glass has good optical properties but is not durable and can dissolve in water, acids, and alkalis when used for a long time. Therefore, choose to buy gemstones that do not contain lead glass and bismuth glass. Other types of glass the quality of gems will be different, such as bismuth glass. However, when purchasing gemstones, you should choose the type that does not contain glass contaminants. and be inspected with an X-ray Fluorescence (XRF) machine only because it can determine the amount of lead in percent. To consider the appropriate purchase price

You are amazing. This video is so informative. Thanks a lot. I have become a fan.
