Description: A quartz crystal with a lovely, light amethyst colour, lovely gas inclusions and interesting elevated patterns on all its termination facets. Three of its shaft facets have a slightly pitted effect, giving those sides a somewhat dull appearrance.
The lesser termination has bits of very pale prehnite and possibly limestone, attached over a large area.
The main termination appears to be without any damage, but there is some damage towards the middle of the crystal (rougly 20 x 15 mm), where it parted from its matrix at an angle. There are a few natural pressure marks.
