The sample is 8 cm x 8 cm. The bladed crystals of greenish Hellandite (Y) are partially altered to brick red Kainosite (Y). There are white and chalky-tan secondary phases in the cracks in the Quartz. From comparison with other Evans-Lou Mine samples the white phase is Lokkaite (Y) and the chalky-tan phase is Tengerite (Y)

Snow-white thin leaves of lokkaite-(Y) with sharp triangular terminations. Image is about 2 mm in length. Specimen obtained from Element 51 (Tim Jokela, Jr.) at the 2009 London, Ontario Gem and Mineral Show. Other Y-minerals on the specimen according to the label include kainosite-(Y) and caysichite-(Y). I haven't determined conclusively which ...
