When you’re on the cutting edge of nerd fashion, you MUST accessorize. Any fashiongeeksta could tell you that. These handmade Cell Membrane Necklace pendants designed by Tiffany and Kevin Ard feature a charming illustration of a cartoonish cell membrane. According to the artist, “Cells are swell!” and are “surrounded by cool things like cytoplasm, mitochondria, chloroplasts, Golgi apparatus..and endo plasmic reticulum”. (No not the Phishy Golgi Apparatus). I think I once caught endo plasmic reticulum after a bachelor party in Vegas. Handmade of sterling silver in Georgia. Cool gift for your chemistry teacher or science nerd sweetheart.
