Do raw garnets need to be tumbled or can they just be polished?


`Raw` or natural garnets can be worked in many different ways. In my opinion, it depends on the quality and individual size of the garnets. If you have a large quantity of decent sized garnets, they can be tumbled. (We have taken very large, well formed pyrope garnet crystals and just polished every face, using a cab machine.) Good sized translucent or transparent rhodolite garnets can be faceted, while large chips can be cabbed.

    I have some large (walnut sized)faceted “star garnets” that my husband and I dug up in Idaho. These are naturally faceted. Can these be polished by just duplicating the faceted sides? There are also a cup full of the smaller ones that we could tumble…would tumbling them bring out the star or would you recommend another polishing method?

    For Gloria, if you really do have \’star\’ garnets I would take them to a lapidary to have them properly worked as a tumbler will only shape and clean them up. The \’Star\’ is formed by the rutile configuration in the crystal, which needs to be oriented at certain angles to \’bring it out\’.
