Charles & Colvard (OTC: CTHR), a fine jewelry company known for moissanite and lab-grown diamonds, has partnered with strategic investor Ethara Capital to expand its lab-grown diamond (LGD) offerings. The deal leverages Ethara's affiliates, who pioneered CVD LGD manufacturing and operate over 3,000 diamond-growing machines, to provide a vertically integrated supply chain. This move enables Charles & Colvard to offer new bridal and fashion LGD jewelry on its e-commerce site and, for the first time, sell loose lab-grown diamonds through its B2B wholesale portal, Charles & Colvard Direct. For overseas jewelry buyers, this signals increased access to consistent, high-quality CVD lab-grown diamonds from a major grower, potentially impacting sourcing strategies for bridal and fashion collections.
Supply-chain impact
Ethara Capital's affiliates are among the largest CVD lab-grown diamond growers globally, with over 3,000 machines. This partnership gives Charles & Colvard a vertically integrated supply chain, ensuring consistent quality and volume for loose stones and finished jewelry. For importers and distributors, this means a reliable source of CVD diamonds in various shapes, carat weights, and grades, which can streamline procurement for bridal and fashion lines.
Wholesale platform expansion
Charles & Colvard Direct, the company's B2B wholesale portal launched last year, now allows approved retailers and independent jewelers to browse and purchase certified and non-certified loose lab-grown diamonds. The platform previously offered moissanite brands like Forever One™ and Forever Bright™. This expansion provides a direct channel for buyers to access lab-grown diamonds with the quality and consistency associated with Charles & Colvard, supporting private-label and custom jewelry needs.
What buyers should watch
Overseas buyers should monitor Charles & Colvard's expanded LGD assortments on charlesandcolvard.com and the B2B platform for new bridal and fashion designs. The partnership with Ethara may lead to competitive pricing and improved supply reliability for CVD diamonds. For sourcing managers, this could be an opportunity to diversify suppliers or secure long-term contracts for lab-grown diamonds, especially for markets demanding ethically produced gems.
Compliance and logistics signals
Charles & Colvard emphasizes responsibly made gemstones and uses 100% recycled precious metals, aligning with growing regulatory and consumer demands for ethical sourcing. The company's lab-grown diamonds are CVD-produced, which may simplify compliance with trade regulations regarding conflict-free diamonds. Buyers should verify certification options and grading profiles available through the wholesale platform to ensure they meet local market standards.
