Natural eudialyte crystal on matrix from the Kola Peninsula, Russia – one of the world’s classic localities for this rare zirconium silicate.
The specimen features a well-defined eudialyte crystal embedded in a contrasting host rock. The deep red to pink coloration stands out against the darker matrix, typical for Kola occurrences. Crystals of this size and visibility are uncommon, making the piece attractive for both collectors and display.
Eudialyte is valued for its complex chemistry and limited occurrence. Fine crystal specimens from Russia are increasingly difficult to source on the European market.
• Crystal size: 19 × 13 mm
• Specimen size: 65 × 40 × 40 mm
• Condition: natural, unpolished
• Locality: Kola Peninsula, Russia
A solid cabinet-size piece with good visual contrast and identifiable crystal form.
