Lugano Diamonds was a high-end jeweler — then its revenue turned out to be inflated

Lugano Diamonds was a high-end American jewelry manufacturer and retailer, founded in 2004 and operating seven stores. In 2021 the investment firm Compass Diversified acquired a majority interest in the company for $256 million, with its founder, Mordechai 'Moti' Ferder, retaining a 40 percent stake. It looked like a successful luxury brand with a powerful new backer.

The picture fell apart in 2025. A preliminary investigation by Compass Diversified found irregularities in the company's financing, accounting and inventory practices. Its chief restructuring officer said Lugano's revenue and operating income appeared to have been overstated, and were being revised to substantially lower numbers. In June the company sued Ferder, alleging fraud, concealment and breach of fiduciary duty.

The allegations were striking: the suit accused Ferder of forging invoices and sale documents, sending out empty-box shipments, falsely recording money from third parties as Lugano revenue, and concealing payment obligations from the company's books. Nearly sixty people said they had been involved in investment contracts with him, and around a dozen lawsuits were filed. Ferder, through his attorney, denied the allegations.

In November 2025 Lugano Diamonds filed for Chapter 11 bankruptcy in Delaware, listing liabilities of $500 million to $1 billion and between 200 and 999 creditors, and sought a buyer for the business. It is a case about the limits of buying a business on its reported numbers: the acquirer paid a quarter of a billion dollars for a luxury brand whose revenue, it later alleged, had been substantially invented.
