“So far, I am the only one in the world that does this”, states Mordaunte – owner, designer and creator (shown below).

In addition to the gemstones, she designs and creates finished jewelry in both men’s and women’s fashions. These include rings, earrings, pendants, and tie tacks, done in sterling silver as well as 14k gold. In keeping with the coffin-shaped design, purchases are even shipped in a cardboard coffin-shaped box. Mordaunte’s clients buy her jewelry for costume decoration, funerary wear, immortalizing a departed loved one, wedding sets, and everyday wear with a “kick”. “Most people don’t realize it’s a coffin shape until you tell them – they just comment that it’s a beautiful stone”, says Mordaunte, “When I mention that it’s a coffin shape, they gasp – “That’s awesome!”. Many customers refer to her business as “The Morbid Tiffany’s”.

Mordaunte started her custom coffin-shaped gemstone “business” from her desk in her basement in the spring of 2000. She offered 3 different stone materials in two sizes. She then set up a internet service-provider website and went into business. Slowly, but surely, the business grew both in the USA and Internationally. More and more interest was revolving around her unusual gemstones, especially the idea of offering them in pre-made jewelry. Being in the IT field, she had never set a piece of jewelry in my life. However, after much research and “trial and error” she started setting her gemstones in oval and marquise pre-made settings.


As the business continued to grow it took on a life of it’s own. Mordaunte began supplying jewelry to celebrities and rock bands that had found her online site. She was invited by the people at OzzFest to be a vendor on their tour. Radio stations and TV shows asked her for interviews. Haunted Houses, Horror Conventions and Gothic Nightclubs contacted her to be a guest and a vendor at their events. In 2005 Mordaunte re-designed the coffin gemstone shape to the perfect 6-sided coffin you see today and has added several colors to her line since then.

The coffin-shaped gems have made many a wicked woman happy and have been used as engagement rings, such as in the examples shown below.

Other jewelers use her stones as a source for their own creations, such as Lyndsay Brown of Idle Hands Designs on etsy who makes them into pendants, rings and cufflinks set in sterling silver:
