Natural Amenities by County: 1970-1996

The USDA published a map that displays how desirable an area is to live based on topographic variation, vegetation, access to water, etc. Green is best, red is worst.

The device a jeweler uses to test for diamond authenticity works by measuring the heat transfer capacity of the stone. A diamond's thermal conductivity is much greater than that of any of the fakes...until recently when moissanite was developed. That synthetic diamond substitute has a coefficient very close to a diamond's, rendering the test unreliable. Even experts are challenged by the moissanite fakes. A reflectivity test had to be developed to guarantee detection.
