What’s the difference between grading and authenticating?

Grading looks at the physical characteristics of an item and marks it against a system that will help define its value. For example, diamond grading is based on a 4C scale that evaluates a diamond’s color, cut, clarity, and carat weight.

Authenticating will determine if your item is genuine and described as claimed. Professional authentication services use reputable experts who specialize in detecting counterfeits and forgeries to verify whether an item is as represented.

Benefits of Grading or Authentication

Having an item graded or authenticated offers the following benefits:

  • Assurance and peace of mind that your item is the genuine article as you were told.
  • Added value, in some cases doubling or tripling your asking price when selling the item.
  • Select laboratories can catalog your item, making it easier to track if ever stolen.
  • Insurance companies may require certification for an item before accepting it on a policy.
