4.1 x 3.4 x 3.4 cm. This is a perfect sphere of siderite from Dalnegorsk - no flat areas, dings or contact, it really is perfect - and the trim job is perfect too, so it sits on just the right amount of matrix. Siderite is typically an accessory mineral on mineral specimen, infrequently remarkable enough to compose a specimen in and of itself - but this is certainly an exception!
