Amethyst and it can not be differentiated with absolute certainty without advanced gemmological testing (which is often cost-prohibitive). There is one test based on "Brazil law twinning" (a form of quartz twinning where right and left hand quartz structures are combined in a single crystal) which can be used to identify synthetic amethyst rather easily. It is possible to synthesize twinned amethyst, but this type is not available in large quantities in the market. Single-crystal quartz is very desirable in the industry, particularly for keeping the regular vibrations necessary for quartz movements in watches and clocks, which is where a lot
Amethyst gasfield were built in 1989 by UiE Scotland in Glasgow, and have 5 and 6 wells respectively in Amethyst East. B1D and C1D were built in the following two years and currently produce from 4 and 7 wells in Amethyst East and Amethyst West respectively. C1D is connected to A1D and B1D is connected to A2D. All Amethyst daily operation and processing is carried out onshore. Personnel only travel to the platforms themselves for maintenance and well work. Produced gas is transported to the Easington Gas Terminal and sold to Électricité de France. Amethyst gasfield Amethyst is a natural gas field
