Synthetic or reconstructed precious or semi-precious stones, unworked

cpc code 34560 covers the production and trade of synthetic or reconstructed precious and semi-precious stones in their unworked state. These materials are increasingly important in the jewelry, gemstone, and industrial sectors, providing a more affordable and consistent alternative to natural stones. The global market for synthetic and reconstructed stones is substantial and continues to grow, driven by technological advancements and rising consumer demand.

Synthetic and reconstructed precious and semi-precious stones are produced through a variety of advanced manufacturing techniques. Common methods include hydrothermal synthesis, chemical vapor deposition, and melt growth processes. These techniques allow for the precise control of the stone's composition, color, and clarity, resulting in high-quality products that can closely mimic the appearance of natural gemstones.

The production of synthetic and reconstructed stones requires specialized equipment and raw materials. Key inputs include high-purity chemical precursors, such as metal oxides and salts, as well as sophisticated growth chambers, heating elements, and other specialized machinery. Energy, water, and skilled labor are also important resources needed for the manufacturing process.

The primary outputs of cpc code 34560 are uncut and unpolished synthetic and reconstructed precious and semi-precious stones. These materials are then typically consumed by industries covered under 34570 Precious and semi-precious stones, worked, not mounted, set or strung and 32300 Jewelry and related articles, where they are further processed and incorporated into a wide range of jewelry, gemstone, and industrial products.
