The crystal has super luster and translucence along with a bright lemon yellow color. Aesthetic, large and particularly fine from this deposit. In fact, although this deposit produces literally tonnage of sulfur for the specimen market today, only a handful of crystals of this caliber have come out, and survived to market. It is metallic in luster, and gorgeous in a case, a trophy for the species at a relatively cheap price compared to what the old Italian sulfurs cost today.
