Sugary and pearly masses of Lovdarite. Evidently it is replacing Chkalovite per Martin Slama Mindat photo.

White fibrous crystals in a 2.5mm area. Lovdarite is a beryllium zeolite found in alkali, silica poor environments in only five worlwide localities. Yubileinaya pegmatite, by Dr. Igor Pekov's standard is one of the greatest pegmatites in the world. In such a small deposit of 26 x 1 meters nearly 50 minerals can be found (Mindat has it at 42 with 12 TL's). It is probably a world record in terms of new minerals per volume according to Pekov. It is a "hyperalkaline" pegmatite according to Pekov. This is type locality for Lovardite.
