Hi I am interested in buying this inside engraver Could you tell me who builds this ? Available still ?
Dear @MegaJadon, thank you for contacting Presidium Instruments. Noted that you are interested in purchasing the Inside Ring Engraver Machine. For purchase, please kindly visit: www.presidium.com.sg/product/engraver/inside-ring-engraving-machine-mini
This video is NOT clear. Each of the Presidium testers results are determined on where the indicator lands either the highest point, or the stable position and if it lands on two different lines. The PGT II the correct reading is the one taken at the highest point as clearly stated in the User manual. If you have the PDT II (Duo) tester the reading is taken at the stable position. Two similar machines but both reading points are different. Read the manual. Plus these machines are accurate, they are just 1 test of many you should take. You need to read many books, get advice, read the user manual and practice before you get some idea. There is no 1 test that can tell you this accurately. Even professionals conduct many tests before making a determination. There are so many things to consider, colour, the structure (patterns under microscope), temperature of the stone, if the stone was clean before testing, is the machine correctly calibrated, wheres the best spot to place the probe etc etc. Its not as easy as you think. Simply grabbing a Presidium and probing a stone is not enough, the Presidium is a great tool but you need to use many other tools/techniques to accurately determine what the gem is. Plus many stones not listed on the tester can fall under different categories. You need to understand what that particular stone is by understanding its chemical composition, colour, hardness etc, it takes many years to learn. But you can always take it to a Gemologist to test.
I have only had my presidium 2 for about 5 months . I have taken very good care of it . rarely move it , haven't dropped it. One night the arm went to diamond and stayed there. . I have tried to calibrate it to no avail. It flings right back to diamond and wont register. Very upset I paid a lot for it and sure cant afford another any suggestions on a fix or is it shot. I cant believe they dont last very long . I only used it maybe two or three times a week to check unknow jewelry. . Anyone else with this problem? any suggestions. It will be along time before I can afford a new one On a fixed income raising my grandson (our daughter passed away from cancer in 2017. I decided to post jewelry for extra income . Someone out there can you tell me how I could possibly fix it ?
Thank you for contacting Presidium Instruments. Kindly drop us an email at service@presidium.com.sg
So it cost $300 to $500 and doesn’t even tell you exactly what it is 😩 Why though. I want to know if my gemstone is an emerald.
Send it to the Gia, they'll charge you $100~ and give you a certificate, but emeralds are stupid easy to distinguish natrual vs synthetic with a loupe and any gem tester.
So my moissanite will definitely pass the test with the presidium diamond mate-a, right?
The Diamond Mate-A will not be able to differentiate moissanite from Diamonds, it will just indicate as "Diamonds". That is when you use the ARI by Presidium to further narrow down the "Diamond" to Moissanite, NAtural Diamond or CVD/HPHT/Type IIa Diamond.
@@presidiuminstruments Thanks for responding, I'm about to buy that machine to test my moissanite.
@@presidiuminstruments Thanks for replying, then any moissanite will pass the test on this detector, I have seen many jewelers use this
@@jalonso8220 ARI will be able to detect Moissanite and even low conductivity Moissanite.
I tested that praesidium shows me red means natural diamond
If the tester indicates red, it means your diamond is a Type IIa and will need to be send to a reputable laboratory for further verification. If the light is blue, means its a natural diamond
The presidium refractive index meter gives wrong reading for both purchases. I bought two thinking that one of them would work fine. For Moissanite it give the reading of 2.00 and for corundum 1.65 or less. How can I fix this instrument?
I am talking about the presidium refractive index meter ii
Gives wrong reading every time. I have two - both are reading inaccurately. It worked fine the first few months, then it is giving wrong readings for both. They do not tell us how to calibrate this instrument. Waste of money.
thank you for contacting Presidium Instruments. Kindly email us at service@presidium.com.sg and state your serial number in the email.
How to calibrate presidium Refractive index meter II. It is giving wrong reading. It show Moissanite as 2.00 and corundum as 160.
How many years machine works before it breaks what is durability ? Is it good not broken easily and electric board circuit PCB well built components ?
Does PRIM II know if gemstone is Nanosital or other ceramic glass ? Identify fake glass gemstones and counterfeit corundum sapphire from real lab grown corundum ?
PRIM II will not be able to identify Synthetic vs Natural
Will the diamond light engage from a lab or mossanite diamond? Also is there a time frame to wait in between testing diamonds?
Can this give false readings from a lab diamond? Reading as diamond and not mossanite?
Thank you for contacting Presidium Instruments. The Adamas is unable to test for lab diamonds, it will give unreliable results.
Is this machine tell RI in every kind of gem stones?
Thank you for contacting Presidium Instruments. it can detect up to 55 gemstones. Only works on loose polished stones. Visit: www.presidium.com.sg/product/colored-gemstone-testers/refractive-index-meter-ii
How can buy
You may purchase the Gem Tester II via our Presidium Estore: www.presidium.com.sg/product/colored-gemstone-testers/gem-tester-ii

Good question ❤
Ist es auch für rough Diamond geeignet?
Thank you for contacting Presidium Instruments. The ARI by Presidium can only be tested on polished stones.
Continued thanks to Armani for the informative demo and overview. The Adamas is an excellent, versatile tester.
Can it tell you if the sapphires natural or lab and same with coloured stones ?
Hi Casey, the SDS II only works on colorless diamonds. Colored gemstones will not be detected.
Hi. How do I know if it’s a diamond or moissanite? If they both are in the same scale zone?
Is acurate?
Hi, thank you for contacting Presidium Instruments. When the indicator stops at a position, the stone tested maybe one of the stones that falls within the black strip. Therefore, you must have basic gemstone knowledge. For more information on the testing and reading results, please refer to ua-cam.com/video/MQubIH5svwM/v-deo.html
Where is the calibration pin I didn’t get one with my unit
Hi Brian, thank you for contacting Presidium Instruments. Kindly drop us an email at service@presidium.com.sg
As you can see in the result there are many possible results because your tester isn't accurate at all! Pls, stop making this tester period!
This is another guessing game gem tester. Don't waste your money.
Could you pls stop creating products that are now fully accurate?
Another useless tester!
Another trash?
Not so accurate! When are you going to make a product that's 100%?

Hello, it's been a while since I saw this video and I barely managed to collect some rough stones. But if I already have facets that I acquired over time, I would say quite a few. Today I am thinking how I am going to identify the raw rubies that I have. The largest is more than 400 carats and in facets I acquired 50 carats in the individual tests that I did on them. So far they are positive but I am still not convinced. and I cannot send to certify until I am sure that they are genuine with AT LEAST 90-% security because they are genuine or false, they will charge me and I only collect and I also do it as an investment and all my savings are there, they come with certificates but that does not guarantee that they are genuine, that is why I need a device like this, the problem would be the biggest
hi this is a tester only for loose stones? or a set ring could also be tested?
Hi, thank you for contacting Presidium. The SDS II can test on polished loose stones and open-back setting mounted rings. Kindly note that it can only test on colourless stones from D to J with a minimum carat size of 0.02 carats
Well i bought it for a purpose and it's not working and fooling. Even not performing basic things, like digital meter is dead. Continues bipping
First of all continuous bipping is a problem, 2ndly digitals meter is not working as shown in the introduction. It must show 2 while pressing Cal but remains dead
Thank you for contacting Presidium Instruments. Kindly drop us an email at service@presidium.com.sg
Promo sm 💘
Is it same with presidium multitester III ? The green is for diamond then the others are not diamond
Price?
Thank you for contacting Presidium. The Gold Karat Tester is no longer available. It has discontinued.
Does it test gold
Thank you for contacting Presidium. Gem Tester does not test gold
I thought I had to calibrate it every time I turn it on. So I’ve been doing that. Now it’s not working right. 😩
Hi can you only check one stone at a time?
Thank you for contacting Presidium. Yes, you can only check one stone at a time
I bought a new one , but when I start the device it automatically shot down in 10 seconds .! Any advise? Thanks
Thank you for contacting Presidium Instruments. Kindly drop us an email at service@presidium.com.sg
If I have a colored diamond will the test still work
Thank you for contacting Presidium. The SDS II can only test on colorless diamonds ranging from D to J color.
Is this the 1mm or 2mm side of the plate?
so basically worthless
A digital one would have been more accurate.
Can this equipment test double refractive gemstones?
Hi Isuru, thank you for contacting Presidium. The refractive index meter II can detect double refractive gemstones, however, it will not be able to provide the birefringence of gemstones with DR
Do not buy this it is over priced and cheaply made, And doesn't work.
