Red Spinel - Vietnam
Contributed by: FMS Admin
Date: May 10th, 2026
Locality: An Phú, L?c Yên District, Yên Bái Province, Vietnam (See on Mindat)
Size: 11 x 7 x 13 mm
Description:
This specimen, which I have been told is rather large for the locality, is really attractive both under UV and in daylight. It fluoresces a rich, vibrant saturated red under longwave. It is not quite apparent in the pictures due to the angle the specimen was photographed in, but the specimen is actually twinned.
