Quartz (Japan Law twin) ex. Ed David Coll.

Item Description

This large, impressive example of Japan-law twinning in quartz was purchased by Dr. Ed David, former science advisor to President Nixon and a chair of the White House Science Office, for $5000 in 1993 (no kidding). It is an outstanding example of good size, which came to me in his large collection several years ago and which I can now afford to sell at a loss compared to what I paid for it (his own cost!). The specimen is very lustrous, very bright, and has an unusually good thickness to it. Most twins of this habit are skinny, but this is fat : 4.5 cm across at the twin plane in the middle! It is nearly pristine, with one tiny ding and one 6mm chip the only problems, despite its size and 3-dimensionallity. it is 925 grams. Twins of this habit, in this size, are uncommon.
