Gemstones are minerals that are treasured for their beauty and durability. A large number of minerals have been used as gems. Their value generally depends on four features: the beauty of the stone itself; its rarity; its hardness and toughness; and the skill with which it has been cut and polished.
Gems are shaped entirely by being ground on abrasive wheels or revolving abrasive discs. For minerals that are no harder than quartz, natural sandstone wheels are sometimes usedRivers of Sibalom are abundant with colored and semi-precious stones. Because of this, Sibalom is dubbed as “Antique’s Gemstone Capital”. Products processed from gemstones are considered novelty items because the products are seldom found in the market. So far, only a few have taken interest in the many possibilities of products that maybe made out of gemstones. Some of these reasons include capitalization and inadequate technical know-how.
