Real Diamond Tester 💎
I rarely ever leave a review but for this I had to! It tests actual diamonds accurately! It also when tested on other minerals doesn’t tick off as if it’s the real thing unlike many of the cheap ones out there. This is the real deal.

Produit arrivé deffectueux. La pile de 9 volt devenue bouillante, j ai acheté un adaptateur 9 volt qui est incompatible avec le testeur. Pour le prix excessif Je m’attendais à mieux produits fortement déconseillé👎👎👎👎👎
