That's what I was thinking. There's really nothing to worry about, as a majority of the gemstones are birthstones. So more than likely, the next gems to become canon and actually show up within the series are Aquamarine, Emerald, Tourmaline, Tanzanite, Zircon, Turquoise, Topaz, Citrine, and Spinal.
