The Sister, Sister star recently asked fans on Twitter if they would be interested in a jewellery line from the twins.
"We're brewing up some really great things for our fans," she added.
Asked about their plans, Tamera told Digital Spy: "We've been getting a lot of feedback about our accessories on the show, and Tia and I are bringing up some amazing ideas.
"We don't know if it's going to be a jewellery line yet, but we will definitely have something for our fans."
She added: "We wanna just share something with them, whether it's clothing, whether it's a jewellery line, we're figuring that out as we speak.
"We want our fans to choose the first item we're going to bring out."
The sisters' reality show Tia & Tamera was yesterday picked up for a second season on Style.
