Pastel Blue EuclasePastel Blue EuclaseColombiaEuclase is not well known as a gemstone—primarily due to its scarcity—but it is much beloved and sought after as a mineral specimen. Very rarely do its well-formed crystals have enough clarity to be cut as gems. The name Euclase is derived from the Latin meaning "easy cleavage"—which is a problem for gem cutters who need to be careful of splitting an unfinished gem. The present pear-shaped stone is large for the species. The skill of the lapidary is apparent in the expert execution of its fancy cushion faceting. This desirable collector's stone is lustrous and has a pastel blue color. Weighing approximately 3.74 carats and measuring 11.32 x 8.03 x 6.0mm None
