Diamond Certified

Diamond Certification Services

Diamond Certified follows a rigorous 12-step process that is the most reliable in the industry. To obtain the most accurate rating and ensure only actual customers are responding, we survey a large, random sample of REAL customers by phone. Diamond Certified surveys a company’s entire customer base to ensure that the results of our study, good or bad, accurately represent the company’s level of customer satisfaction. The Diamond Certified Company Reports include all responses for each Diamond Certified company.

In order to protect respondents’ privacy, they are identified by their first name and last initial. The name of a respondent if the response is overtly negative or their first name is easily identifiable due to its uniqueness (either due to its rare usage in American society or because the sample size is small). The purpose of this is to protect the anonymity of respondents while including their feedback for other consumers to review.

Diamond Certified companies must score Highest in Quality and Helpful Expertise® (90+ on a scale of 100) and pass all of our credential-based ratings. Only the Best Pass the Test™. Diamond Certified eliminates mediocre and poorly performing companies by requiring such a high score. There is continuous research to rate the companies to ensure they maintain their high performance.

Diamond Certified Companies Are the Only Ones with the Highest Rating in Quality and Helpful Expertise®.

Websites that provide reviews can be useful, but they should be used carefully. There are key differences between how Diamond Certified Resource (DCR) conducts research and how review sites collect reviews. Review sites post reviews from anyone who chooses to write them, which means that legit, spontaneous reviews are mixed with fake and cherry-picked ones that come from a company’s best customers, family, and friends. Diamond Certified is able to back your purchases from top-rated companies with their Diamond Certified Performance Guarantee, whereas review sites do not. As a result, consumers are naturally encouraged to look for Diamond Certified companies first.
