1972 BLUE-CAP TOURMALINE!
This is a superb, unrepaired, San Diego blue-cap tourmaline from the famous find of 1972 at the Tourmaline Queen Mine. This specimen has excellent luster and a glassy top. Only a few dozen specimens of this caliber were mined by Bill Larson and Ed Swoboda with their team of helpers, that winter. Most are singles, with no accenting matrix. Of the larger pieces, most are now housed in institutions. What comes to market today are few and far between, seldom any of consequence. This is an intensely colored crystal with the best color atop, a thick band of riveting blue. More importantly, it is from the core pocket, with the lustrous terminations, as opposed to the several dozen further pieces recovered in nearby pockets (which had less lustre and less intense color). This specimen is accented nicely by a bit of lavender lepidolite encrusting over the top, and by a swirl of white Albite at the base. Despite its thickness, it has intense color. The reason for this unusual intensity in such a fat crystal is that the piece tapers towards the base, from the more equant termination, thus allowing more light to come through. Else, it would be as opaque as these generally are, except at the tips. Ex. Chuck Houser Collection.
