There are two qualities that automatically make an art piece more impressive - when it's really big or really tiny. In the case of Japanese artist and jeweler Shinji Nakaba , it’s the miniature scale of his intricate skull carvings that caught our attention. The diminutive artworks are each crafted from a single oyster pearl, adding a unique layer to the sculpture’s statements. While pearls are pristine and often associated with purity, skulls represent darkness and finality. The carved skulls are mounted to rings, turning the pearls into jewelry - but in a very different way than we are accustomed to seeing them.
