Our Team

Kimberfire wouldn't be what it is today without our talented client service and in-house manufacturing teams—and everyone else who makes it all possible.

Rachel Tucker, BFA, AJP

Owner & Designer

Rachel was born in Winnipeg and moved to Calgary in 1995 to pursue a degree in Fine Arts, majoring in Visual Communications and Illustration. Upon graduating, Rachel worked for several years in the fashion industry before becoming a fine jewellery designer in 2002. Creating everything from custom designed diamond engagement rings to belt buckles for the Calgary Stampede, Rachel honed her skills as a premier jewellery designer. She moved to Toronto in 2008 to work for and eventually become a partner at Platinum Unlimited where she became an award winning designer. She then started her own business, Rachel Tucker Studios in 2016, specializing in custom designed luxury pieces for exclusive jewellers across the country. In 2026, Rachel Tucker Studios acquired Kimberfire, Toronto's premier bridal jewellery concierge. Rachel now leads both companies as Owner & Designer, continuing to create outstanding, one-of-a-kind jewellery for clients throughout Canada.
