Hay que insistir. El aparato funciona porque lo hemos probado con joyas que sabíamos que eran buenas y otras que sabíamos que no. Pero y tengo que decir que hay veces que pita y otras que no en la misma piedra o sea que cuidado con dar por malo algo que puede ser un brillante, mejor repetir la operación unas cuantas veces porque le cuesta. Eso sí, si la piedra es mala no va a pitar lo pongas como lo pongas.
