- It’s been almost two years since I wrote about Highway, Adva Rozenshtein’s graduation collection. I remember how fascinated I was by this girl’s magic powers and as it turned out there is twice the magic! He goes by the name Adar Sidahi and yes, it’s her brother we are talking about. Anyways, their new collaboration is called Volcano, “an experiment with boundaries, layers and flexibility of matter”. There is nothing I like more than layering, and with that being said, Adva and Adar’s way of layering all these piles of gold makes me want to reach out and touch each and every piece of jewelry!
