Hardwood pendants

Having no clue what colors best suit my mother’s wardrobe I made her six identically shaped necklace pendants from different materials.

I used the same technique as with the heart pendant, milling it from both sides on the CNC and getting at it with a lot of sandpaper afterwards. For the materials I used Oak, Padauk, Bocote, Purperheart and some strange blue shiney plastic I can’t seem to figure out of what it actually is which really frustrates me because the stuff is freaking awesome but I can’t buy more not knowing what it is!
