The close-up view of each stone type shows a relatively true image of the crystalline structure and the colouring. This is suitable for grained slabs to a limited extend only. In regard to the colour matching, please take an original sample of the stone from your furniture store as a basis.
This is a fine-grain structure from the main mixture parts of feldspar (white) and quartz (grey, fully transparent). The green specks or layers are caused by the yellow-green epidote combined with the radiant dark green actinolite. The darker parts contain the dark silicate biotite (a type of mica) and compact green hornblende.
Para-gneiss is formerly clay-sand sediment rocks, which has been generated under high pressures and temperatures during folding up of maintain ranges. The patterns, noticeable in some plates, can be assumed to be relics of former conglomerates. Accordingly, most of the light, oval portions - in cases some measuring up to 10 cm - effectively were rounded "pebbles? formed by flowing water.
