futuristic jewelry



Novemeber, 2011. Siwei was an University of Minnesota undergraduate student making a gypsum cement model for the first time. Outside the architecture building, he struggled mixing out the lumps with the stick, the mixture was thickening, tick tick. Rolled up his sleeves, he dipped his forearm into the freezing cold mixture, reached out every corner of the bucket, withhold the cold, and dispersed the lumps one by one. The mixture was no longer freezing, getting warmer and warmer, from forearm to his whole body, he had the most realistic “the little match girl” experience possible. At the end of the day, the cast was successful, and Siwei is in deep love with cement.

SIWEIWARE was founded in 2017 in New York City by Siwei Ren. We specialized in designing and crafting sophisticated jewelry that transforms.

Siwei means mind in Chinese. Our goal is to provide men and women with minded concrete jewelry that make you look sharp every day.
