So a few days ago I was thinking of a more subtle way of signaling that you're bi other than using a flag, pin, or wearing any of the multitude of hybridized Venus/Mars symbols for it. I later saw a simple short string of glass beads online made up of the 3 stripe colours and wondered if there are natural minerals/rocks that have the same hues. After scouring countless bead listings on Etsy I finally settled on the 3 natural bead materials shown here, which I think is pretty close to the shades of Fuchsia/Hot Pink, Lavender, and Blue.
From top to bottom, the rocks are: Eudialyte, Charoite, and Lapis Lazuli. I might also have gone with Ruby, Amethyst, and Sapphire which have satisfactory hues, but I don't think clear crystal beads aren't half as interesting to look at as patterned rock. And most likely the gems have to be synthetic as making real ruby and sapphire beads is cost prohibitive due to their rarity. I prefer natural materials any day for bracelets, necklaces, etc.
Anyway, this is just for fun and more a style/fashion topic that ties into my gem hobby than a serious discussion post. It just wanted to share this with other bi's.
