The feldspar quarries at Mølland (of which there were 11 in the 1930s), Iveland, Agder, Norway have produced many of the world's best specimens of Aeschynite-(Y) and museum quality Monazite-(Ce) and Spessartine crystals. Collecting is now actively discouraged in any of the quarries but this fine older specimen comes from the superb systematic collection assembled by the brothers Martin and Michael Günther (1951-2007 & 1956-2021). Entirely Aeschynite-(Y), it comprises two (possibly twinned) crystals with the smaller of the two showing nice development of its external faces in several directions, but with one side and most edges of the larger crystal fractured, but revealing the wonderful resinous internal lustre that is not seen on the weathered outer crystal faces. A remarkably large example of this very rare species.
