O banco
Equipamento de lapidação e instrumentos de ensaio
Tudo o que se encontra na bancada de um lapidário é fabricado por alguém, e a maioria destas empresas são pequenas empresas que se dedicam a esta atividade há décadas. Aqui fica registado quem fabrica o quê: as máquinas que cortam e polem, os instrumentos que testam o resultado e o software que concebeu a pedra antes de alguém lhe ter tocado.
Não fazemos análises de equipamentos nem os classificamos. Cada registo foi compilado a partir do próprio site do fabricante e inclui a página de onde provém e a data em que foi consultado. Não existem aqui links de afiliados e ninguém paga para ser incluído na lista. Nos casos em que uma marca conhecida tenha cessado a sua atividade, o registo indica-o, pois essa é, normalmente, a informação que precisa de saber.

Um comprador que compreenda como uma pedra foi lapidada e como foi testada interpreta de forma diferente a descrição apresentada por um comerciante. Os instrumentos aqui utilizados são os mesmos que os laboratórios utilizam, em escala de bancada, e saber o que um testador portátil pode ou não determinar tem tanto valor como saber qual o laboratório que emitiu o relatório.
