MSH is the type and only known locality for monteregeianite-(Y). It is not common here. The crystals on this specimen are small, but they are pale pink and translucent – which is quite rare.

In the two close-up photos (FOV 2.3 x 2.6 mm), the crystal near the center is 0.6 mm long. About 1.2 mm of a larger crystal is visible on the right. The rest of this crystal is hidden behind yellowish calcite “cones”. Altogether there are 6-7 pink crystals in the photo, but, in at least one case, only the termination can be seen. Flipping back and forth between the photos helps. In the full-view photo, the monteregianite-(Y) is at upper right in the cavity.

Single item shipping weight 2.8 oz. IOutside the USA, the stated postage and packing rate applies up to a total weight of 8 oz (225 g). It is no longer possible to save on postage by using a padded envelope.

Within the USA, postage now varies by destination. For total weights up to 13 oz, it ranges from $4.50 to $7.00 (including packing etc). Above 13 oz (up to 16 oz), I will use “own box” Priority Mail. The rate, including packing, varies from $8 to $10.
