After doing some research online, I have found the following beads have been used in designs including unakite. ( Green jade, green turq., rose quartz, peridot, peridot colored crystals, sunstone, goldstone, green jasper, wood beads, cherry quartz, czech glass, pink coral, red sponge coral, black onyx, hematite, olivine colored crystals, copper green opal )
Some of these looked great and I would have never thought to use some of these beads until seeing them incorporated into the designs.
Thanks for replying to this message and giving great ideas.
