Screen Shot 2560-05-23 at 8.13.49 AM“More is more is more is more is more.”  That’s the way Los Angeles based jewelry designer Marrin Costello feels about accessorizing. With over 20 years of designing jewelry, Marrin is the powerhouse behind the global luxury lifestyle brand Marrin Costello Inc.  Her jewelry has been featured on shows such as American Idol and in gift bags for various events such as the Daytime Emmys. It has been worn by celebs Jessica Alba, Selena Gomez, Vanessa Hudgens, Bailee Madison, Chloe Lukasiak and Miss USA and has also been featured in Vogue, InStyle, US Weekly, Daily Mail and WhoWhatWear.


Costello is a California native who’s love for jewelry began when she was a kid and received a bead kit as a gift. She turned that love into a highly successful business with a huge social media following and also recently became the face of her brand, modeling for her company’s marketing pieces. She is relatable and compelling and you can see her personality in the work she designs. One side of Marrin is very sweet and compassionate and the other side is extremely driven and hard working with a gritty tenacity. Likewise, in Marrin’s line you’ll find chain work pieces that are delicate, very simplistic and feminine sitting right next to edgy pieces that make big statements and combine leather, stones and mixed metals-and Marrin would tell you (and she’s right) to wear these all together and layer ‘em up!

Her new Resort Collection will be coming out in June and in the Fall she will launch a luxury ring collection. She is collaborating with clients like RedBull and UCLA to create custom jewelry. She is also collaborating with celebrity stylist Mercedes Natalia on the MCxMN Collection. She revealed that a men’s collection is in the works, so standby guys, she’s not leaving you out!

When asked what advice she would give to other people wanting to create their own businesses she said, “Anything is possible…Ask for help. If you don’t know what to do there are people out there who want to help. Finding your confidants or people in the industry or even in different industries who can add a different perspective, ask them and if they can’t help you, 9 times out of 10 they’ll point you to someone who can.”
