Equipos para el tallado de piedras preciosas e instrumentos de ensayo
Todo lo que hay en el banco de trabajo de un tallador lo fabrica alguien, y la mayoría son pequeñas empresas que llevan décadas dedicándose a ello. Aquí se recoge quién fabrica qué: las máquinas que cortan y pulen, los instrumentos que comprueban el resultado y el software con el que se diseñó la piedra antes de que nadie la tocara.
No evaluamos equipos ni los clasificamos. Cada ficha se ha recopilado a partir de la propia página web del fabricante e incluye la página de la que procede y la fecha en que se consultó. Aquí no hay enlaces de afiliados y nadie paga por aparecer en la lista. Cuando una marca conocida ha dejado de operar, la ficha lo indica, ya que eso suele ser lo que usted necesita saber.

Un comprador que comprenda cómo se ha tallado una piedra y cómo se ha analizado interpreta de forma diferente la descripción que ofrece un comerciante. Los instrumentos que aquí se utilizan son los mismos que emplean los laboratorios, a escala de laboratorio, y saber qué puede y qué no puede determinar un analizador portátil tiene tanto valor como saber qué laboratorio ha emitido el informe.
