At Duarte & Bastos, clients will find the new Grape Color Change Fluorite from own mine in several shapes and sizes, both calibrated
and free size. It changes color when reacting to the light. In daylight,
its original color is Grape, but under the light of an incandescent lamp it becames red.
    Fluorite is well known and prized for its glassy luster and rich variety
of colors. It is a mineral with a veritable bouquet of brilliant colors like: purple, blue, green, yellow, colorless, brown, pink, black, reddish orange and more. The most popular color for Fluorite is a deep purple which can rival Amethyst in its finest examples. Some of the most eye-catching examples are multi-color Fluorites with distinctive bands and zoning.
    The word "fluorescent" comes from the mineral Fluorite which commonly fluoresces blue and has been known to glow yellow,green, red, white or purple. Some Fluorites display different colors under longwave UV light and shortwave UV light, and some will even demonstrate phosphorescence in a third color!
    All of these factors contribute to making Fluorite the second most popular mineral among collectors after quartz, and why fluorite earns the reputation as "The Most Colorful Mineral in the World". Gem quality specimens achieve high prices favored by mineral collectors .
