When you think of statement jewelry, some of the first things that come to mind are large pieces, bright color combos, and unusual shapes. Bibi van der Velden knows that it’s what jewels are made of that sends the true statement, though. The NYC born, London and Netherlands bred designer crafts her pieces with rare materials like Chinese jade, Italian coral, and oh yeah – 40,000-year-old Mammoth tooth dug up from the Siberian tundra! These are true investment pieces (as in one day they might end up in museums), and you can buy one for yourself from Bibi’s first ever trunk show on Moda Operandi. The mammoth jewelry catches your eye before you have any idea how old it is. She sculpts the tooth into everything from simple teardrop earrings ($2,025) to elaborate sea snake rings ($3,600). I also love the Memorabilia collection. These orb pieces display loose diamonds and pearls – doesn’t get more memorable than that! Pre-order on Moda Operandi through September 12th.
