What processes do natural stones go through to become jewelry?

Natural stones undergo a series of processes before they become jewelry. This process includes various stages from the extraction of the stone to the final product, and each stage is designed to increase the aesthetic and commercial value of the stone. Here are the main steps in the process of turning natural stones into jewelry:

1. Mining and Extraction

• Definition: Natural stones are formed as a result of various geological processes in the earth's crust and are usually extracted from mines or river beds.
• Period:
  • Open Pit Mining: Used when stones are close to the surface. Large stones such as granite and marble are extracted with this method.
  • Underground Mining: Used when stones are found deep down. Precious stones such as emerald, sapphire, and diamond can be extracted with this method.
  • Alluvial Mining: Used to search for precious stones in river beds or deltas. Diamonds and gold can be found with this method.

2. Classification and Selection of Stone

• Description: The extracted raw stones are graded according to size, color, clarity and quality.
• Period:
  • Visual Inspection: Stones are examined for color, clarity and internal flaws.
  • Classification: Stones are divided into categories based on their value and the purposes for which they will be used. Higher quality stones are suitable for jewelry making, while lower quality ones may be reserved for industrial use.

3. Cutting and Shaping

• Definition: Stones are cut and shaped into specific shapes to be made into jewelry. This stage aims to enhance the shine, color and overall aesthetic value of the stone.
• Period:
  • Facet Cut: Flat surfaces (facets) are cut to best reflect light. Common in precious stones such as diamond, sapphire, emerald.
  • Cabochon Cut: The upper surface of the stone is rounded and the lower surface is left flat. Used for stones such as opal, moonstone, agate.
  • Tumbled: Stones are rolled in a tumble to make them smooth and shiny. Common in stones such as quartz and jasper.

4. Polishing

• Description: The surface of the cut stones is polished to give them shine and smoothness.
• Period:
  • Sanding: Fine scratches and imperfections on the surface of the stone are sanded away.
  • Polishing: Using special polishing machines and pastes, the surface of the stone is made smooth and shiny. This stage emphasizes the optical properties of the stone.

5. Processing and Stone Refinement

• Description: Some stones may be treated to enhance their color, clarity or durability.
• Period:
  • Heat Treatment: Stones are exposed to high temperatures to change or intensify their color. Common in gemstones such as amethyst, sapphire, and emerald.
  • Filling: Cracks or flaws in stones are made invisible by filling them with glass, resin or oils. Common in emeralds and rubies.
  • Coating: A thin coating is applied to the surface of the stone to increase its color and durability. It can be used on stones such as topaz.

6. Mounting and Design

• Description: The processed stones are placed in mounts to be used as jewelry. This stage determines the aesthetic and functional structure of the jewelry.
• Period:
  • Metal Selection: The metal in which the stone will be set is determined (gold, silver, platinum, etc.). The color and hardness of the metal must be compatible with the stone.
  • Mounting: Metal frames or holders are made for the stone to sit in. This frame ensures that the stone stays securely in place.
  • Setting the Stone: The stone is placed in the mount and carefully fixed. This process is done by the jewelers.

7. Final Control and Certification

• Description: Jewelry is subjected to quality control tests and certified where necessary.
• Period:
  • Quality Control: The jewelry's stone and setting are inspected for flaws, cracks, loose stones, or other problems.
  • Certification: A certificate is issued that documents the quality, size, clarity and other characteristics of the stone. Certificates are usually issued by independent gemological laboratories.

8. Marketing and Sales

• Description: Prepared jewelry is offered for sale in stores or online platforms.
• Period:
  • Product Photography: Professional photos of the jewelry are taken and used on online sales platforms or in catalogs.
  • Pricing: The price of the jewelry is determined by the quality of the stone, its cut, its weight and the value of the setting.
  • Sale: Jewelry is offered for sale in retail stores, auctions or online platforms.

9. Maintenance and Customer Service

• Description: After sales, maintenance of the jewelry and services provided to the customer are also important.
• Period:
  • Care Instructions: The customer is informed on how to maintain and clean the jewelry.
  • Warranty and Service: Warranty services are provided for the maintenance and repair of jewelry.

Conclusion

The transformation of natural stones into jewelry requires careful workmanship and a series of technical processes. The transformation of a stone from its raw state into a final jewelry involves a process ranging from mining to cutting and polishing, from mounting to sale. These processes reveal the natural beauty of the stone, turning it into a valuable and useful jewelry.
