Forma-se geralmente através de depósitos sucessivos de sílica em cavidades e fissuras da rocha, dando origem a massas nodulares ou preenchimentos de contornos suaves, por vezes marcados por faixas finas ou variações subtis de tonalidade. Apreciada em coleções pelo seu equilíbrio visual e matéria densa, a calcedónia é ideal para a constituição de conjuntos homogéneos, para venda à unidade ou para uso profissional que exija um volume considerável de espécimes naturais.\u003c\/span\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\/\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan dir=\"auto\" style=\"vertical-align: inherit;\"\u003e\u003cspan dir=\"auto\" style=\"vertical-align: inherit;\"\u003eCada peça é conservada no seu\u003cstrong\u003e estado bruto, sem polimento nem tratamento\u003c\/strong\u003e, de forma a preservar a estrutura mineral original.
