In recent years, “Suishohdake” on Narushima island has been a prolific producer of transparent colorless Japan-law twins (often incorrectly labelled “type locality” Japan twins at mineral shows outside Japan). A high percentage of the quartz crystals here are twinned (single crystals uncommon), mostly in square thin tabular habits around 1 cm, uncommonly to 3cm, of the “closed” twin variety, generally quite flattened, and additionally twinned according to the Dauphiné or Brazil laws, as demonstrated by natural surface etch pits. Usually seen in collections as loose twins without matrix, rarely on matrix and as interlocking groups of up to six twins. A few contain pyrite crystal inclusions, or limonitized pyrite crystals on their surface. Formed in cavities in a network of quartz veinlets filling fissures in a friable Tertiary sandstone. The Naru village government has now prohibited collecting here because of the bothersome amount of sand being spread around the landscape and onto the road by overzealous collectors.
