Kidwellite & Strengite (rare Arkansas combo) Carmichael Coll.

Item Description

Kidwellite and strengite are rare to uncommon hydrated iron phosphates. This is an oustanding, very rich and rare combination from this obscure Arkansas locale. A cluster of large pistachio-green kidwellite botryoids is flanked by a rich field of tiny, sparkly, lavender, strengite microcrystals. Choice material from the Eugene Carmichael Collection and a must for the species or locality collector.
