These crystals were purchased from a stone shop over 10 years ago. They are being sold as a set of three. I was told that they have lines (growth lines) from the triangular mountain shape that formed as the crystals grew. The largest crystal originally had a rack inside. 【Size】 Large: Width 8cm, Depth 4.5cm, Height 7cm Medium: Width 2.3cm, Depth 2.3cm, Height 3.5cm Small: Width 2.4cm, Depth 2.0cm, Height 3cm 【Weight】 Large: 322g Medium: 22g Small: 16g Type: Crystal
