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.
The coarser crystalline parts consist of lightly grey quartz, bright feldspar and large, dark reddish-brown garnet crystals. In addition, black biotite of almost dust grain size is enriched in the fine-grain areas. The fairly equally distributed warm, yellow shade is caused by finely distributed limonite, an iron oxide.
The Indian sub-continent consists, apart from extensive areas covered by volcanic rocks, in the largest part of very old, metamorphic rocks, which were generated from rocks of sediment or magma origin at very high pressures and temperatures close to melting point. Under these extreme circumstances, a typical setting of minerals for such rocks came into being. In this case, stable minerals such as garnet were generated, which is, in a transparent, compact form, in great demand as a jewellery "Stone".
