Is This Really Good Turquoise? Who Knows?
Gift Article from the New York Times
From the article: "The lack of a grading system for the popular stone has prompted a father-son team to spend the last five years working on one."
Editors Opinion: Some people might enjoy knowing how their stone measures up to a grading system. However, a person should mainly buy what they like, what fits their intended use, and fits within their budget.
If you are going to use the stone, pick one that looks good in a ring at arm's length, in a bolo tie or buckle from three feet away, or that complements your clothing and character, etc.
If you are going to use the stone in jewelry or in an item that will be used, be aware that turquoise is a delicate stone that is easily scratched, chipped or stained. Wear and damage can be reduced by a setting that will protect the stone and common sense about not wearing the stone when your activity might cause the stone to be abraded or broken.

Algorithm Raises New Questions About Cascadia Earthquake Record

The doubts focus on the reliability of using turbidite in the sedimentary record as evidence of an earthquake. The rock sequences in which turbidites are found can have gaps in the sedimentary record, and turbidite events can be triggered by more events than earthquakes.
