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.
Blue Eyes is a bright grey, medium-grained rock that is almost mono-mineral - consisting mainly of labradorite. According to position and angle, individual, startlingly bright blue to green-bluish, shimmering labradorite crystals, in relatively even distribution, sparkle over the polished surface. The marvellous blue sheen is produced by fine refraction lamella within the crystals of the labradorite. The black silicate fractions may sometimes appear stripe-like in the otherwise homogenous plate structure, differing block by block.
Geologists describe igneous rocks where the feldspar contains mostly calcium as anorthites. Blue Eyes is made up of labradorite for the most part. Anorthites occur as independently existing plutons (complexes of igneous rocks) but more frequently as layers and bands in differentiated gabbro plutons. As a consequence of very extended periods of cooling, over millions of years, the magmas crystallised out into massive, medium to coarse- grained, igneous rock.
