Comparing Synthetic To
Natural
Rubies, grown as rods for industrial use, are readily recognizable as synthetic because of their shape. Manmade stones that are cut as gems are not so easily identified. However, microscopic examination can reveal characteristic patterns of inclusions (foreign particles), bubbles, and striations (growth bands) that can distinguish between natural and synthetic stones, even revealing the location from which a natural stone came or the process by which a synthetic stone was made.
Methods of Synthesizing
Several methods are currently used to manufacture rubies; each has advantages and limitations. The most popular methods can be categorized into two main types: production from melt, in which powdered material is heated to a molten state and manipulated to solidify in a crystalline form, and production from "solution," in which the required aluminum oxide and chromium are dissolved in another material and manipulated to precipitate into a crystalline form. Verneuil's flame fusion and Czochralski's crystal pulling are the most commonly used melt techniques, while flux growth and hydrothermal growth are the most popular versions of solution processes.
