About precious stones (including diamonds, but not industrial diamonds) and semi-precious stones, unworked or simply sawn or roughly shaped

cpc code 1631 covers the trade and production of precious stones, including diamonds, and semi-precious stones in their unworked or roughly shaped form. This industry plays a vital role in the global jewelry and gemstone markets, providing the raw materials that are essential for the creation of high-value, luxury products. The trade in precious stones is a significant contributor to the overall economy, with a complex supply chain that spans mining, cutting, and distribution activities.

Production process

The production of precious and semi-precious stones typically begins with mining operations, where the stones are extracted from the earth. Once mined, the stones may undergo basic processing, such as cutting, polishing, or shaping, to enhance their appearance and prepare them for use in jewelry and other applications. The specific techniques employed can vary depending on the type of stone and the desired final product, but often involve the use of specialized tools and equipment to carefully shape and refine the raw materials.

Production inputs

The primary inputs for the precious and semi-precious stone industry are the raw, unworked stones themselves. This includes a variety of gemstones, such as diamonds, rubies, sapphires, and emeralds, as well as other semi-precious stones like amethyst, topaz, and quartz. In addition to the raw materials, the industry also relies on specialized machinery and equipment for mining, cutting, and polishing the stones, as well as skilled labor to perform these tasks.

Production outputs

The primary outputs of the precious and semi-precious stone industry are the refined, cut, and polished stones that are used in a wide range of jewelry and decorative products. These stones may be sold directly to jewelry manufacturers, wholesalers, or retailers, or they may be further processed and incorporated into finished goods. Other industries that may consume the output of cpc code 1631 include 3691 Jewelry and related articles, 3699 Other manufactured articles n.e.c., and 4641 Wholesale of textiles, clothing and footwear.
