Are some gemologists better than others? The distinction from natural citrine and heat treated amethyst is possible with expensive test in a high tech laboratory. Because citrine is a cheap stone, dealers assume all citrine in the market are heated for "security reason" because the test is more...
We know greenhouse gases can change the climate based on multiple lines of scientific evidence point to the increase in greenhouse emissions over the past century and a half as a driver of long-term climate change around the world. Laboratory measurements since the 1800s have repeatedly verified ...
