Mineral Notes: Sulphur belongs to the non-metals. Its crystal structure consists of ring-shaped S8 molecules linked together by weak molecular forces. It is most commonly formed and found in volcanic regions where it is precipitated directly from Sulphur-rich gasses, a process called sublimation. It can also be formed by the incomplete oxidation of Hydrogen Sulphide gas. The last source comes from sulphates which are converted by bacterial activity.
Description: The specimen consists predominantly of a single, large doubly terminated pyramidal crystal. The form is easily seen even though there is a smaller twin abutting one side. The colour is a deep canary yellow and there is marked transparency, giving a rather gemmy appearance.
