Synthetic jewels are created through various scientific processes that replicate the conditions under which natural gems form. One significant method used for creating certain types of synthetic gems is the flux-growth process.
Understanding the Flux-Growth Process
The flux-growth process is a technique used to synthesize crystals, including several popular synthetic gemstones. This method utilizes a material known as flux.
-
What is Flux?
Flux is a solid material that serves a crucial purpose in this process. When heated and melted, it acts as a solvent, dissolving other materials much like water dissolves sugar. -
The Dissolution Stage:
Gem-forming chemicals are dissolved within the molten flux. This creates a rich chemical solution containing the building blocks for the desired synthetic crystal. -
Crystal Formation:
As this dissolved chemical solution is gradually cooled, the conditions become right for the dissolved materials to precipitate out and form crystals. These crystals grow over time within the flux solution.
Gems Created Using Flux Growth
Today, several synthetic gems can be successfully created using the flux-growth process. According to available information, this method is used to produce synthetic versions of:
- Emerald
- Ruby
- Sapphire
- Alexandrite
- Spinel
By carefully controlling the cooling rate and the composition of the flux and dissolved materials, scientists can produce synthetic crystals that possess the same chemical composition and crystal structure as their natural counterparts.
