Star Rose Quartz is very high quality rose quartz that has a star of light with 4 or 6 rays that only appears when the stone is polished in a spherical shape. The stars come out most dramatically in strong light such as the light of the sun - sometimes with a holographic effect that seems to rise up out of the crystal.
Star rose quartz is only found in a few locations in the world. Rose quartz is opaque to translucent microcrystalline quartz of pink to rose-red colour. Some rose quartz contains microscopic rutile crystals which are oriented at right angles to the c-axis of the rose quartz in three directions, each 120 degrees apart. When viewed at a specific angle with a source of light a star-effect is visible. This is known as asterism. What is interesting is that this star formation only appears when the stone is polished in a spherical shape
