In collaboration with twin influencers and breast cancer survivors Tiffany and Tegan, we present this beautiful jewelry featuring their "T and T Twin Talk" logo. The chic pendant necklace features the sisters' signature design in sunny 18kt yellow gold over sterling silver. Singapore chain from Italy adjusts from 24" to choker length and finishes with a lobster clasp. Ross-Simons will donate $10 from every logo item purchased, up to $100,000, to the Pink Fund -- a non-profit organization that helps provide financial assistance to breast cancer patients in active treatment.
