And whom did the New York designer turn to for inspiration? Just her friend and mentor, acclaimed jewelry designer Judith Ripka (who has her own QVC line).
Shoshanna's Fashion Jewelry Essentials launches on QVC on Aug. 10 at 9 p.m. ET, and the collaboration promises an eclectic offering of pieces that work for day or night.
"Accessories, to me, are what make a woman's look her own," Gruss says. "I designed the collection with Judith to be distinctive, versatile, and easy to wear. I have had so much fun mixing and matching the pieces."
The affordable line of costume jewelry will range from around $20 to $80. You'll find bold pieces, including the Shoshanna Crystal Drop Statement Necklace, and more feminine designs, such as the Shoshanna Crystal Encrusted Cascading Drop Earrings.
"With her innovative sense of style and creative approach to design, Shoshanna's jewelry line is a natural extension of her brand," says Diane Paccione, vice president of merchandising for QVC.
"We are thrilled to not only launch her exciting new venture but also welcome her to our list of high-profile designers."
Gruss tells fans on QVC.com that one of her greatest passions is jewelry.
"I've been a customer and admirer of Judith's for as long as I can remember, and share the same philosophy with her that clothing and jewelry should be versatile, wearable throughout the day, and appropriate for every role a woman plays in her life."
Gruss says versatility in jewelry is as important as it is in clothing.
"I love being able to wear a dress to a daytime luncheon and then out to a concert later that night, with just a change of jewelry and accessories," she says.
"I think fashion and jewelry should be fun, contemporary, and fresh."
This isn't the first collaboration for Gruss. Here's a swimwear collection she worked on with Charlotte Ronson.
