A large, well-formed, dark yellow crystal of londonite is clearly visible on the matrix.
There is a nice color contrast with the matrix which is partly reddish.
On one side of the crystal you can see a very small V (3 mm wide): it is due to contact with the matrix, with the microscope you can still see very small residues of white and reddish material.
However, it remains a sample of notable quality!
Specimen weight:450 gr.
Crystal size:mm. 18
Overall size: 63mm x 50 mm x 90 mm
