Labrador Blue Pearl
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 pearl is a coarse-grained , grey-blue to silvery-blue plutonic rock of uniform structure and consists up to 85 % anorthoclase feldspars. Due to their atom zone structure, these reflect the light incidence in such a way, so that the individual crystals shine alternatively in bright blue, depending on the viewing angle. Black biotite and black-green pyroxene give Blue Pearl an intense colour contrast.
This syenite was generated as an intrusion of a potassium and sodium-rich granite melt, whereby the chemism promoted the formation of mainly anorthoclase feldspars. Because of the long cooling period, identical molecules were able to gather in the melt and form the large, blue-shimmering feldspar crystals.
