Looking for advice for finding a platinum tennis bracelet lab grown around 3ct total weight

Hello all,

As my headline states, looking for a tennis bracelet with lab grown diamonds. However, I can't seem to find many, if any in a 3ct total weight approx and in a plat setting. Does anyone have suggestions? I looked on Blue Nile, Clean Origin, Ritani, and was a little surprised I don't see plat as an option. Any guidance would be really helpful on places that sell this combo.
