Description

The Quartz crystals shows milky, translucent quality - it is covered with a chatoyant layer of micro-crystals of second generation. Along one side you can see extrem dark, very intense Amethyste crystals - these show incredible luster, sharp termination and al of them are double terminated. The color is as good as Amethyste could be world-wide - maybe compare-able with darkest, most intense crystals from Uruguay. Please not, that I did photography under daylight - only minor backlight and it is a true explosion of color. The top of the large quartz crystal is undamaged, it consists of several steps and even the bottom is healed, so I can judge this piece as floater. All these uncountable tiny crystals are undamaged.
