The Raw Silk Ivory is a material with Ivory background with no red or pinkish colours in the material. Raw Silk Ivory is quarried in 3 quarries. The production of Raw Silk Ivory is around 300 cbm per month from these 3 quarries. These quarries have been in production for more than seven years and are quarried from a depth of more than 50 m. This type of Raw Silk is exported in processed slab form to the United States & Europe. Rough Granite blocks of this type of Raw Silk is exported to Chine, Taiwan and Europe. The defects that are normally observed are of minute cut joints. It is sometimes difficult to overcome these defects while processing into slabs in spite of using resin.

The Red Raw Silk is more uniform in structure. However, there is quartz intrusion in some of the blocks which can be avoided while selecting the blocks.
More than 50% of the Red Raw Silk is exported from India to Europe. Local factories in India are also processing both types of Raw Silk for sale as slabs to the U.S. market. Most of the slabs are used in kitchen counters in the U.S. market.
