Presidium Multi Tester III (PMuT III) All-in-One Instrument for Testing Diamonds, Moissanites and Diamond Simulants

Initially I thought this multi tester was unreliable. Turns out I was the weak link. After reading other reviews and watching the product videos, I realized I wasn’t putting adequate pressure on the stone. After being mindful of the stone cleanliness, probe angle, and pressure, I’m identifying stones with precision. This is a prograde device which does require practice and patience. I’m extremely happy with the purchase.

This diamond tester does not work and it is very inaccurate it reads everything as simulated even stones that I know that are genuine gia diamonds my employee tested a customer's diamond and had to tell them it was imitation they were so upset and the woman actually started crying this damaged my business beware before you buy this product

Very accurate tester. All my moissanite jewelry came up as moissanite. All my diamond jewelry came up as diamond. Does the job. 5/5

Good product, just make sure you center the tip from the diamonds and hold the reader 90 degrees for accurate reading

Husband wanted me to buy this to keep kin my purse for the "haters" he got me a big diamond ring lol . Works very well everytime def worth the price, not some crappy one u can get.

Fits well in the hand. Seems quite accurate, but testing tiny stones is a challenge because the probe can touch the metal and in a few cases the very tiny stones registered as moissanite. I like that cz doesn't register and that white topaz and white sapphire show as simulants. AC adapter needs to be purchased seperately.

Accurate BUT doesn’t last long - at this price point, I should’ve gotten years out of this tool. However, in less than a year of use, the “ready” light just blinks and it never officially turns on. Very disappointing for the $220+ price point. When it did work, it was great. It was easy to use and very easy to carry around with you. I just fully expected it to last longer.

Probably the worst diamond tester on the market at an insane price do not buy

Just like the description

El producyo aparenta muy buena calidad, pero no es lo que promete. Tengo casos en los que un diamante HPHT es leido como diamante cuando esta sobre la placa de aluminio suministrada y una vez montado en oro lo lee como Moissanita. Casos en los que pequeños diamantes naturales los lee como Moissanitas. Y casos en los que a las Moissanitas las lee como diamantes.. Aun limpiando, aun cambiando pilas, aun verificando angulo de toma, aun con todo lo que se recomienda hacer, lls errores de lectura son persistentes, por lo que no es confiable su uso. para eso, vale mas comprar un diamond selector de 150 pesos (conductividad termica) y un Moissanita terster de 150 pesos (conductividad electrica) y con menos del 10% de lo que vale este producto tienes los mismos o incluso mejores resultados de lectura, ya que con esos aparatos baratos si temgo lecturas persistentes de lo que se trata.

I received without a cover tip and used, the packaging is damage and worn out.

Works well and fast delivery , recommended seller.

It's a little expensive but it's doze the job well.
