Leo Robbins and Sons, the four-store chain based in Philadelphia better known as Robbins Diamonds, has filed for Chapter 11, two weeks after five of its creditors filed an involuntary chapter 7 petition against it.

According to court papers, the company does “not intend to liquidate [its] business,” but will use Chapter 11 to “restructure [its] obligations and reorganize [its] affairs.”

In court papers, owner Jerry Robbins said the company owes $6.8 million to Sovereign Bank and $3.4 million to trade creditors.

Top unsecured creditors include the Salant Group ($899,700); R and R Grosbard ($257,679); Leo Schachter and Co. ($182,772); the New Jersey branch of Overseas Diamonds ($159,496), whose parent company has filed for the Belgium version of bankruptcy; and True Romance ($119,595).

The chain has 52 employees and locations in Philadelphia; Allentown, Pa.; Newark, Del.; and Hamilton, N.J.
