A classic old locality! This is quite a nice and rare combo, from the Lane Quarry in Massachusetts. Cut and rough combo with a fine faceted stone of light yellow color and excellent clarity. Datolite is a rare gemstone and it is difficult to cut as the hardness varies in different orientations, but when done well they are brilliant! Datolites can have a dispersion greater than diamond. The crystal is bright, sharp and un-dinged on the display side, contacted on back and broken on the base, it displays well. Very uncommon to see a Massachusetts Datolite combo like this!
Impressive and a Northeastern US classic! Sharp, clear and bright gemmy Datolites up to 2.4 CM with selective faces colored a nice cognac hue sit on a contrasting green Prehnite. As esthetic as you can find, the main crystals are in perfect condition but non detracting damage is noted on a few smaller crystals and at the edges. Despite this it displays very well and is a striking specimen from this old locale.
