Charles & Colvard, Ltd. (NASDAQ:CTHR), the sole manufacturer of moissanite lab-created gemstones, The Most Brilliant Jewel in the World TM, announced today that it will join the Russell Microcap ® Index when Russell Investments reconstitutes its family of U.S. indexes on June 25, according to a preliminary list of additions posted June 11 on www.russell.com. Membership in the Russell Microcap ® Index, which remains in place for one year, means automatic inclusion in the appropriate growth and value style indexes. Russell determines membership for its equity indexes primarily by objective, market-capitalization rankings and style attributes. Randy N. McCullough, Chief Executive Officer of Charles & Colvard, commented, “We are extremely pleased to be included in the Russell Microcap ® Index. We believe the results of our diligent work over the past six months to improve our financial performance and stock price have been validated by the selection of our company by Russell Investments for benchmarking the true microcap opportunity.” Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for both passive and active investment strategies. An industry-leading $3.9 trillion in assets currently are benchmarked to them. Annual reconstitution of Russell Indexes captures the 4,000 largest U.S. stocks as of the end of May, ranking them by total market capitalization to create the Russell 3000 ® Index and Russell Microcap ® Index. These investment tools originated from Russell’s multi-manager investment business in the early 1980s when the company saw the need for a more objective, market-driven set of benchmarks in order to evaluate outside investment managers. Total returns data for the Russell Microcap ® and other Russell Indexes is available at http://www.russell.com/indexes/performance/default.asp. About Charles & Colvard, Ltd. Charles & Colvard, Ltd.
