Talk about rare gem crystals - these bright peridot crystals were mined in Egypt in the early 1900s, and are just not around anymore, unless they turn up out of the blue from some old collection. All four of these crystals are terminated and completely gemmy. A real collectors item for sure! 1.1 x 0.5 x 0.4 cm, 1.1 x 0.4 x 0.2 cm, 0.8 x 0.6 x 0.5 cm, 0.6 x 0.6 x 0.3 cm
