This is a huge fluorescent calcite specimen chunk in the rough! It measures approximately 8 inches from opposite corners in length. It is 3 inches in thickness. This calcite is a naturally formed mineral specimen from the location of Nuevo Leon, Mexico. The calcite that comes from this area will turn a vibrant pink under longwave UV (365nm) and a ghostly blue under shortwave UV (254nm). It even displays the property of phosphorescence after being exposed to shortwave, slowly dimming when the light source is turned off.

• Measures 8 inches in length from opposite corners
• UV reactive to shortwave(blue) and longwave(pink)
• phosphorescent (blue)
• Extracted from Nuevo Leon, Mexico
• Rhombohedral crystal habit
• 6 pounds 9 ounces

All measurements are approximate. The images you see are of the exact specimen in this listing. This specimen is still in its rough form, direct from the mine it was extracted from.
