I’ve seen several punny iterations on the “big diamond” – pieces that use the diamond form/shape in different materials. This sterling silver ring by Carolyn A’Hearn will let you indulge your presumably ironic interest in bling without the big bucks that would involve.

This piece is USD $60; it is available in 10k yellow gold for USD $350 and in 14k yellow gold for USD $545. Each is handmade in Brooklyn, NY, so factor that in to shipping time.
