An exceptionally rare combination piece featuring an intergrown cluster of sharp platinum crystals, with gold deposition on the surface. 23.51 carats (4.7 grams). very SHARP! For the thumbnail collector, one can go get cubes with a little patience. However, to get a cluster, to get a platinum specimen that is more than just a single loose crystal, now THAT is a challenge. I have seen very few crystallized specimens that are elevated to this level (and size, above 1 cm). It is a competition-level thumbnail specimen.Joe Budd Photos
