The Marcus Lemonis Fashion Group has added Ellison Eyewear to its fast-growing retail and fashion portfolio.

Lemonis, the star of CNBC’s “The Profit,” featured Ellison Eyewear on an episode of the show Wednesday.

Lemonis paid $350,000 for a 50.1 percent stake in the business, which manufactures and sells sunglasses. He plans to develop product and build up the business.

Ellison Eyewear was founded by Chicago-based entrepreneur Aristotle Loumis, and sells American eyewear brand with handmade Greek frames, priced from $95 to $120. Among the product line’s features, UVA and UVB protective frames, Teflon-coated screws help block and secure the thread components to avoid loosening screws and nuts, and a trademarked letter “E” engraved on a galvanized metal cap on the left temple tip.

“I have traveled the world seeking the best caliber materials, skills and stories. This is the Ellison journey,” Loumis said.

The two-and-a-half-year-old Marcus Lemonis Fashion Group has invested in brands selling jeans, ready-to-wear, cashmere, scarves, T-shirts, footwear and watches. His investments include Inkkas Shoes, Printed Village, Flex Watches and Susana Monaco, and last fall, Lemonis launched Marcus, a specialty chain selling women’s contemporary fashion, footwear, accessories, books, home decor, chocolates, gifts and the artwork on the walls.

The Ellison sunglasses are sold at Marcus stores, at wearellison.com, at select specialty retailers, through trunk shows and corporate activations.
