This week’s biker-chic stack is all about the bold and the badass. Like a studded black leather jacket in jewelry form, Lauren Wolf’s point-up black diamond eternity band kicks off this baller stack. TAP by Todd Pownell’s concave diamond ring brings tough-girl texture and glittering spiked diamonds to the party. Our stack is twinning + winning with an insanely beautiful vintage Victorian double halo ring. And because too much is never enough, we top off this tower of power with another vintage two-tone band, encrusted with six shimmering rocks.
