Quartz (variety red quartz) with Quartz.
EB66AG6: Quartz (variety red quartz) with Quartz
Between 1997 and 1998 there appeared in the 2nd Sovietskii Mine from Dalnegorsk specimens of red Quartz with a very different habit from the usual, elongated, crisscrossed, and forming very "sculptural" groups. Although at that time it was thought that they would continue to come out, as soon as they appeared they disappeared and they have not been seen again. From that extraordinary time we have rescued this elegant specimen in which the red Quartz is partially covered with white Quartz.

Quartz (variety red quartz) with Quartz.
EA62AL5: Quartz (variety red quartz) with Quartz
Groups of red Quartz crystals, elongated, many of them doubly terminated, intergrown, and forming very "sculptural" groups - a very different habit from the usual. Finds of this type of Quartz in Dalnegorsk were quite ephemeral and as they appeared, they quickly disappeared too, so it is not easy to get such elegant specimens as this one. The red Quartz is partially covered by a second generation of white Quartz.
