Hello Great videos and good advice. I looked on the internet for kamelien oel, camellia oil and they all have some color while yours looks white.can you explain this please? And where is a good source to buy it in usa. Please asap,since I might have to return the stones I bought. Best Brigitte

[@GermanGemcutter]

Hi Brigitte, i have bought it many years ago in a Bonsai Shop. It is traditional used to protect equipment such as scissors from rust. You can use nearly every other clear and colorless oil. The individual RI of oils can be found online. Dont forgett some oils smells strong which makes the work a little uncomfortable. I have also used a clear foodoil for example. I used the camelia oil only because i have bought enough and dont need it any longer for Bonsai Equipments. Thanks for watching

[@brigittewagner6848]

Thank you for your answer. Would liquid coconut oil at 1.43-1.46 RI be okay for rubies and sapphires? I think they are fake but look quite beautiful and were inexpensive from Etsy in India.They claimed to sell only natural stones and even gave a card from a gemologist that states that they are sapphires and rubies, but there are no inclusions. I wonder what the material could be. Glass, leaded glass, crystal,rhinestones? I have no idea. Does anybody have experience with this? Cheers Brigitte

[@fabianrehmann8023]

Thanks for this wonderful Video. I am wandering how likely will i be permited to execute your tests at the sellers place? Have you got experience to share on this issue?

Can i try this method to check an amethyst ?

[@GermanGemcutter]

Yeah you can also test Quartz with this method. Try to lay the focus on the typical Inclusions like fingerprints or tiny mineral Inclusions(needles, crystals) look for color zoning, often you can find some straight and/or angular growth patterns in natural Quartz. Another helpful Test, if you have enough experience, is to check the Stone in good light. Often purple CZ looks like Amethyst. CZ has a much higher Dispersion(0.065) than a natural Amethyst(0.013) so if you see a lot of Fire(many small points of light in the colors of a rainbow) it is a CZ.

Does a diamond pen tester work if its 9 on the mohs scale?

[@GermanGemcutter]

It depends on the tester itself, some electronic testers have a fine enough scale, but in general i wouldn't suggest using a diamond tester for colored gemstones. As i shown in the Video such doublets or assembled stones have only a thin layer of the Material on top, that they try to imitate.

Yet another very intressting and informative Video,, it is shocking the lengths unscrupulous dealers go to to con people, I have learnt so much from your videos Micha, thank you!!! Do fake and simulated corundom floreces under uv light?

[@GermanGemcutter]

As far as I know, the synthetic corundum is UV active, I'm not sure if every color of it is UV active🤔 Synthetic spinel is also UV active. Many years ago a guy told me that some natural blue Sapphires can also be UV active. I later talked to an old Goldsmith about it, he had a lot of natural Sapphires collected from old gold jewelry and he tested it with me and yes, he had a few natural specimens that were UV active. So always be careful with just one test, several tests are usually required to determine if a Gem is natural or synthetic. It is always better to do different tests. With the test in oil, a lot can be identified or excluded, but almost 100% security is only possible in one of the large laboratories. They have the equipment to examine all possible properties. Nevertheless, the test with oil or with UV is always a very helpful, easy and cheap way of making a selection in advance. Testing a Gemstone with UV light is also very interesting ... Thank you very much for your kind words👍

how can you test with raw sapphire

[@GermanGemcutter]

Same Method(use a clear and colorless oil) and you will get a much better view inside the stone. Especially with some raw stones it is difficult to recognize something, then it only helps to cut or polish one or better two surfaces (opposite). Of course, this is not always possible. In general good lighting helps a lot. A flashlight with small selective lighting can also be very helpful for this test, to spot inclusions in gems and raw stones.
