Willemite is usually formed as an alteration of previously existing Sphalerite ore bodies and is often associated with Limestone.
Yes, ultraviolet light can be used to identify willemite, a mineral that usually shows a green fluorescence under short-wave ultraviolet light. This fluorescence property is a key characteristic used in mineral identification.

Zinc ore consists of zyncite which is red, franklinite which is black, and willemite which could be any color.
Three minerals that glow under ultraviolet light are fluorite, calcite, and willemite. These minerals exhibit fluorescence, which is the emission of visible light after absorbing ultraviolet radiation.
Fluorite: Fluorite can exhibit a fluorescent response under ultraviolet light, emitting various colors. Calcite: Certain varieties of calcite, such as Iceland spar, can fluoresce under UV light, appearing red, blue, or green. Willemite: Willemite can fluoresce a bright green color under ultraviolet light due to traces of manganese.
Zinc is obtained from zinc blende/sphalerite ore (zinc sulphide)
Some examples of fluorescent rocks include fluorite, calcite, willemite, and scheelite. These minerals contain trace elements that make them glow under ultraviolet light. There are many other types of rocks that can fluoresce as well.
Minerals that typically fluoresce or glow under black light include calcite, fluorite, scheelite, willemite, and some types of opals. The fluorescence is caused by the presence of certain impurities or elements in the mineral structure that react to the ultraviolet light emitted by the black light.

Minerals that glow under ultraviolet light display the property of fluorescence. This phenomenon occurs when minerals absorb UV light and emit visible light at a longer wavelength. This effect is commonly seen in minerals such as fluorite, calcite, and willemite.
