This oldtime cluster from the Mount Ida area exhibits the best qualities of Arkansas quartz. The crystals are transparent, lustrous, well formed and free of damage or contact, except for peripheral crystals. What truly makes this specimen unique is the quite evident, thin, rusty, septae, that lie sandwiched between the largest crystal and the one behind it. The largest crystal measures a whopping 14 cm in length. This is another fine example of the collecting tastes of Peter Bancroft, even for a common mineral!
