Bavenite is very rare at MSH. It is found - very infrequently - only in the marble xenoliths. This is a very good example (ex Laszlo Horvath). A minor shortcoming is that most of the bavenite is on the “back” side of a pectolite crystal and thus requires a bit of manipulation to see clearly. Aside from the pectolite, the bavenite is associated with small green magnesio-arfvedsonite prisms and tiny (pseudo)cubo-octahedral apophyllite. (None of the associated minerals are significant examples – just FYI.)

FOV in the close-up photos is 3.5 x 2.4 mm or 2.4 x 3.5 mm (depending on the orientation). The largest bavenite plates are ca 1.1 mm long. You will need 15-30X to view.

Single item shipping weight (with TN case) is 3.3 oz (94 g). For shipments outside the USA, up to a total weight < 8 oz (225g), this can be combined with items from this or other auctions for the same postage.

Within the USA, postage for total weights up to 13 oz ranges from $4.25 to $6.50 (including packing etc) regardless of destination. Above 13 oz, I will use “own box” Priority Mail. The rate, including packing, varies by destination from $7.25 to $9.50.
