A fine, large crystal of lustrous and translucent, equant, colemanite measuring 4.2 cm across is aesthetically perched on smaller colemanite crystals. Partial secondary overgrowths on the main crystal have given it a slightly amber hue. Unusual robust form combined with coloration makes these desirable. Old material, surely.
