Signed MJ vintage costume jewelry
Most likely, the initials MJ stand for Marie Jennifer, an owner of the company that produced costume jewelry from 1978 to 1999 in Providence, RI.
Traditionally, MJ craftsmen made decorations from alloys of silver or gold tone metals, possibly plated with gold or silver, but never made from silver or gold. And there are no markings indicating silver or gold on jewelry. Moreover, very often this is a combination of two alloys in one piece. There is one more feature of the jewelry of this company – many decorations can be used both as brooches and pendants. Also, the jewelers of this company often used multi-colored enamels and rarely used stones. The motifs include traditional American holidays – Christmas, Halloween, Easter, and classic designs. Vintage costume jewelry of this brand, which operated during the 1970-1990s is collectible.
Noteworthy, there are several companies in the vintage jewelry market that sign their products with two letters MJ. However, the marking on the back of the products, which consists of only two letters, nevertheless differs from the markings of the same name from other manufacturers. In particular, the markings of the decorations highlighted in this publication are two capital letters inside a rectangular frame. In addition, both letters are capitalized and printed. While the marking of products from other manufacturers is either without a frame, or j is small, or in capital, but without an upper dash.

According to some sources, MJ belongs to MJ Enterprises started in 1977 in Rhode Island. But this is completely wrong, and this source most likely means the products of M Jent. My research on this brand led me to the names of several jewelers, but none of them are the authors of featured here jewelry. In particular, Marc Jacobs, Mj Jewelers Llc, Marvin Jewelers MJ (canceled 28 February 1995) and Miranda Jewelry Ltd. (active 1989-1992).
