This time I got something special for You: Impressive 5 ruby crystals embedded in a dark hornblende matrix from the famous Longido mining area in Tanzania. The ruby shows a vivid red color under daylight and a striking bright red fluorescence under UV light, making it highly desirable for collectors. The hexagonal crystal structure is well-preserved, displaying sharp edges and a fine natural texture. A perfect addition to any mineral collection, especially for those passionate about fluorescent specimens. Fluorescent in UV light - using Convoy LW UV flashlight 5 big crystals: 1) 127g - 5,3 x 4,6 x 2,0 cm 2) 130g - 4,7 x 4,1 x 2,3 cm 3) 107g - 4,5 x 4,3 x 2,1 cm 4) 97g - 4,8 x 4,2 x 2,0 cm 5) 108g - 4,9 x 4,6 x 1,9 cm Condition as on pictures. Very aesthetic specimen much better in person. Color is very difficult to reproduce in the pictures. Some pictured specimens show slightly different shades that seen with a human eye. Generally in my opinion the colors in reality are slightly prettier.
