Synthetic Spinel Production Methods
To understand synthetic spinel, you'll need to know about its two primary production methods: the Verneuil process and flux growth.
The Verneuil process, also referred to as flame fusion, involves dropping powdered chemicals through a flame, where they melt and crystallize into synthetic spinel. This method results in curved striae lines, which can indicate synthetic origin.
Flux growth, a more time-consuming and costly method, uses a solvent to lower melting points, allowing for controlled crystallization over an extended period, typically up to a year.
Both methods produce lab-created synthetic spinels that exhibit similar optical and physical properties to natural spinels. However, synthetic stones often lack the natural inclusions found in genuine stones.
The chemical composition of synthetic spinels can be tailored to improve specific characteristics. For instance, cobalt content in synthetic blue spinel produced via the Verneuil method deepens the color.
Moreover, the absorption spectrum of synthetic spinels differs from that of natural spinels, aiding in identification.
When examining a spinel, look for:
- Curved striae lines (Verneuil process)
- Absence of natural inclusions
- Differences in absorption spectra
- Unnaturally vivid or consistent coloration
