Garnet for the 1st (Root); Carnelian for the 2nd (Sacral); Citrine for the 3rd (Solar Plexus); Peridot for the 4th (Heart); Aquamarine for the 5th (Throat); Iolite for the 6th (Third Eye); and Amethyst for the 7th (Crown). Whew! I feel better already. 32" to 34" endlessly, and temporarily, strung (no clasp, one long loop).
