What jewelry testing equipment do you use?

[@taofeeqaweda6270]

Same one u use here but i dont understand...i hv some stones but dont kwn wht its

[@aliciamariediys1069]

Do you know more about the gold tone pendant with Jade? I have the same one and wasn't sure about it. Did you test the diamond above? If it fake? Please help! Thank you

[@nabzhusnuk3049]

Its such a shame it doesnt pick up ZIRCOMLNS

[@nabzhusnuk3049]

Its such a shame it doesnt pick up ZIRCONS

[@samriddhanand]

Eyes....best one....with 576 megapixle of resolution. It is funny that people use machine to identify gems in West. Here in India If you go to jwellers and use this machine to identify gems...you will be in an awkward position....BTW good meachine for rookies

[@tbacon2784]

The clear stone in the ruby necklace you bought yourself could be spinel, topaz, or a white sapphire. Did you know that years ago spinels were so commonly used in fake jewelry, that many people, including my sister and I grew up believing they were fakes! Now they have come i to their own and are going up in price.

[@patrickbutcherine142]

The closer the needle is to the end of the corresponding black line means its QUALITY STONES!! Each line is each type of gems threshold so that means lesser quality gems should read like half way or more towards the left and QUALITY STONES MAX OUT!!

[@Calicokittylover]

You are so fortunate to have inherited the emerald ring and the ruby ring (other video) from your grandmother. They are absolutely gorgeous - just my style - plus the sentimental value!!

Thank you Texas Gal your video was very beneficial. I had just received my new presidium in the mail but had no clue as what to do with it bc it came with very limited instructions. Now I can test all my stones and accurately price my jewelry for sale. YOU ARE SPECIAL, THANK YOU & GOD BLESS🤗

[@patzycraftzypatricia]

Awesome I want that toy because I have lots of stones to test thanks for sharing

[@222clevelandavenue9]

Thank you for the video. I've been waiting to see how you liked it. I just now ordered one for myself for Christmas!

[@TexasGalTreasures]

I'm so glad I got it!

[@trendaware216]

Where did you order this from

[@1112Hades]

I mean Emerald and Aqua are the same type of minerals just different coloration

[@kimoamadal4626]

The green cabochon (drop shape) seems to be an aventurine which is a variety of quartz.

[@douglascornett6605]

Even though the tester was in the Topaz, Sapphire range, doesn’t mean it’s Topaz. There are a lot of jewelers that use White Sapphires. My concern is when it overlaps like that. Then there are other tests that must be performed to make sure they are natural, if they have been treated, or if they are specific stones.

[@sthisnthat2748]

What kind of tests would you recommend?

[@lindacaldwell6251]

Going to purchase one today and thought I would watch you. I have been in the business for a long time and never had one! Thanks

[@StevePhillips]

This video is loads better, more fun and easier to follow than those so called parading as expert professional ones.

[@raulgongora5288]

Thanks my dear very interesting to find if whole precious stones are real or false. Blessings

[@jimgordon4685]

Imperial Jade is more of a color, the two types of Jade are Eastern Jade or Jadeite [more transparent/translucent], where Western jade is Nephrite Jade which is softer & Darker. Chrysoprase Is pronounced Cr-is-oprase not Cairoprase. I hope this heps.

[@TexasGalTreasures]

Jim, Thank you so much!

[@gemlover1042]

Jadeite and Nephrite falls commonly as Jade. But Jadeite has valuable and rare.nephrite is common. but they are all come under Jade.

[@patrickbutcherine142]

Iolite is the mantle rock for OLIVINE/PERIDOT! Also look at the metal gems are set in!! Usually the best stones are set in high quality gold and platinum, BUT ALOT OF OLD OLD OLD OLD JEWELRY IS SET IN THE OLD SILVER OR COPPER/BRONZE/LEAD/ WHATEVER ALLOY OF THE AREA IT WAS MADE IN!! YOULL find gem quality Muscovite and old style cut diamonds and other RARE RARE RARE GEMS in old ass jewelry!! Nice demo of this tester. I found a placier deposit. I have rough gemstones of every mineral!!! I believe I have a 30.1g/19.4dwt/150.5 carat diamond or clear garnet, or something super special!! Theres only a couple gems that do the optical phenomena that LORRAINE Does!! I'm tryin to save to get it tested!

[@reginamoriggi5886]

Lovely tester. Thank you very much.

[@TexasGalTreasures]

Thank you, Regina!

[@patricknorton9948]

Got a cheep gemstone tester from Amazon (made in China) and it tested my water glass as nephrite jade and my real Maw sit sit jade as a diamond so I returned it.

[@hollywood61973]

Your nail polish is good 😄like a diamond

[@BOLOBuddies]

It is a bit confusing when it falls in 2 or 3 different lines.

[@cscjb]

12:05 is probably green chrysoprase, otherwise it wouldve shot-up to near nephrite and jadeite considering both are similarly conductive.

[@cscjb]

before identifying something immediately as the most "obvious" looking because it's luxurious or more expensive because it's "EMERALD OR JADE" because it's green, do search up color-names before the name of whatever the indicator is pointing to the closest, considering gems such as nephrite and jadeite are completely different varieties of minerals, as well as ruby and sapphire are different varieties of corundum, thermal and electrical conductivity of stones and the elements that make up the content of the stones is what's making the indicator on your device shoot up all the way to diamond when it's diamond and the others when it's around the others. If it's not shooting up to jadeite or nephrite, it's not Jade. The same reason the device isn't shooting up as quickly when it goes to glass. If you use a handheld device like one of those horrendously made but surprisingly accurate diamond selector devices that take 9v batteries, you'll even see how Jadeite and Nephrite will shoot up unbelievably quickly to high readings on the device. Such as right about where the ending of the black column that indicates nephrite, joins with the one that does with jadeite.

[@cscjb]

Also Chrysoprase which you can pronounce as 'Cry-so-praise' is basically just another form of chalcedony, which everyone basically knows as agate.

[@TexasGalTreasures]

Thank you, Koodge!

[@cscjb]

@@TexasGalTreasures Mhm! Anything to help out. I'm alright at the stuff so I'd love to help people figure out more on it so they can use the information better to their advantage.

[@justmeonthebeach]

Very fun tester, thanks for sharing.

[@jonnywaselectric]

Thanks for the video. Ive tested hundreds of stones with one of the $10 diamond testers and compiled a list of what number they go up to on the scale with it set at 1, 1 being glass and 10 being diamond, my list does correspond to the scale on that tester, saph and ruby 8 to 9 for example. The test isnt perfect as with your device as it wont differentiate a lab grown stone and a genuine, its great to see if something is glass though, there is many more glass stones on the market then there is lab grown.

[@ooboytrends]

Nice Tester and explanation with example

[@TexasGalTreasures]

OoBoy Trends, :) Thank you very much!! :)

[@romanvirec2186]

Never rely on thermal conductivity testers only! They are more for fun than serious gem identification.

[@unnamedjoe9554]

agree! also the stone we need to test need to be cleaned with water and hand soap and brushed with toothbrush

[@shinyshinythings]

Hi Roman, I know this is an old comment, but what process is used for serious gem identification?

[@oldpalmcity]

@@shinyshinythings Experienced certified Gemologist eye and microscope.

[@samriddhanand]

@8:38 it's white sapphire (low quality)

[@toniagirard5670]

I just received one of these for Christmas. I calibrated mine and did do some testing. Pleasantly surprised that some tested for being real stones. My question is, when testing, do you just touch the needle to the stone or do you actually have to press it all the way down just like you have to when you calibrate? I did it both ways. With diamonds, it went all the way up, regardless. I could just touch it with the needle and it registered. Just want to make sure I'm doing it correctly. Thanks

[@RayyanGHunzai]

That is amazing, thank you for sharing your experience. After testing some of my items I can now bank few thousands :)

[@ravenred201]

thank you so much for doing this. It was very helpful. I am going to buy one of these. Need a gold tester too!

[@bingohall1333]

I will get one similar to this, next year or buy one, just before Christmas. Glass and calibrating must remember that one.

[@karenpetrasovits7174]

Very cool, I'll have to check it out. Thanks for sharing.

[@TexasGalTreasures]

Karen, :)

[@bjrockhound9241]

From what I have read, these testers are unable to determine the difference between many synthetic and genuine colored stones because they have very similar conductivity. On the other hand, it is good for making sure if the stone is glass. But that then brings me to the question - how effective is this type of tester when the natural gemstone has been glass filled?

[@heidar62]

Thank you for your information. it means you are very rich by having Ruby, Saffhire, Diamond, Nephrite and etc. welldone

That machine drives me crazy. Its a love hate relationship.they should come out with one where the lines dont intersect. And if you are told you have a diamond, but its moissonite, how do you know. I guess you have to purchase the tester for that too. But you did a great job . I know i would have decided on the same things you did when testing.take care.

Great video, really enjoyed. I be back and check the other videos.. I love stones. ❤

[@krisushi1]

This really doesn't seem too helpful, especially when there are those using this only to list jewellery for sale. It doesn't tell the difference between synthetics, Moissanite and Diamond, the myriads of Garnet or Beryl colours etc. How would you begin to test a 'Watermelon Tourmaline'? This wouldn't be at all helpful with my personal jewellery collection as I tend to purchase gems that are unique and not easily chosen. Chrysophrase is relatively new to the gem industry and is an aqua colour stone. Thanks for showing this as I was recently told about it but really doesn't suit my needs. I think I'll have to save more!

[@rayw2707]

Swarovski glass is glass, glass is glass. Natural gemstones are real gemstones. Lab gemstones are real gemstones. But even if it points to the diamond section, it might not be diamond. It might be moissanite.

[@nancyeaton731]

I've had one of these for a few months now and it's great for some things, but the category I find difficult is rock crystal. I get no registration at all into the quartz range or even into glass. There are a lot of stones I have that I know are not plastic or glass that just don't register at all. Is anyone else finding this? It would seem that it should register into the quartz category.

[@gemlover1042]

if the gem lab made with same composition, it will show exactly same. so be aware of it.
