American Marconi Wireless News - A New Way to Shine: MainStreetChamber Holdings, Inc. Launches DiamondBrokerUSA to Empower Everyday Entrepreneurs

LAS VEGAS, NEVADA / ACCESS Newswire / October 22, 2025 / MainStreetChamber Holdings, Inc. (OTCID:MSCH), a diversified holdings company specializing in brand licensing, consumer products, and entrepreneurial ventures, today announced the launch of DiamondBrokerUSA, a direct-to-consumer and micro-entrepreneurship platform centered on fine lab-grown diamond jewelry.

DiamondBrokerUSA will enable individuals and small business owners to purchase curated packages of lab-grown diamond jewelry at wholesale pricing. Each package includes an assortment of rings, bracelets, earrings, and pendants designed for resale through e-commerce, social media, and in-person retail channels-creating a scalable business opportunity in the rapidly expanding lab-grown diamond sector.

DiamondBrokerUSA will be headquartered in Beverly Hills, California.

"Lab-grown diamonds have completely changed the jewelry industry," said John Bellave, CEO of Advanced Licensing, a wholly owned subsidiary of MSCH and exclusive licensor of DiamondBrokerUSA. "Consumers today are more informed, value-driven, and environmentally conscious than ever before. Lab-grown diamonds offer the same brilliance and beauty as mined stones-without the environmental impact or inflated pricing. This model not only democratizes luxury but empowers people to turn that demand into their own business."

MainStreetChamber Holdings will support DiamondBrokerUSA with strategic development, licensing infrastructure, and operational resources-aligning with MSCH's mission to build accessible, socially responsible business ventures across consumer product categories.

"DiamondBrokerUSA represents an exciting new growth opportunity," said Larry Kozin, Chairman & CEO of MainStreetChamber Holdings. "It allows entrepreneurs to replace a full-time income while working part-time from home. As we finalize our product line-set to debut at the MSCH Convention in late January 2026-DiamondBrokerUSA is actively recruiting Leadership and Market Developers locally, nationally, and globally through the sale of Exclusive Territory Licenses."
