Keep your tiny treasures safe in this week’s sentimental stack. A tower of vintage and modern heirlooms, this collection features four diamond-encrusted guardian bands surrounding an exquisite antique bloodstone locket ring. Two contemporary channel-set eternity bands, a white diamond wonder from TAP by Todd Pownell and Satomi Kawakita’s black diamond Absolute band, combine wabi-sabi playfulness with a sense of strength to anchor our stack. Atop that lie seven Georgian-era diamonds, clutched in a botanically carved gold band; then our 18k gold centerpiece, a working locket ring dated from 1865, faced with darkly rich bloodstone. Add in one final protecting band, a mid-century marvel circa 1950 with baguette diamonds set in powerful platinum.
