Honduras has hundreds of opal prospects and mines, although most high- quality opal is produced from small informal mines in the cool tropical highlands of southwestern Honduras. In particular, the Tablon mine near Erandique is based on the country’s biggest deposit where the opal occurs in large blocks of black basalt. Miners hand-chisel the boulders to extract small vertical veinlets of thin, colourful precious opal, including black-seam opals and black-matrix opals. Seam opals, varying from near paper-thin to rare specimens more than 1 cm thick, have a crystal clear, milky white, slightly blue or brownish orange colouration because they are so thin, the gems tend to be cut with the black basalt forming the back of the stone forming black-matrix opals.
