Kim Kardashian & Kanye West engagement ring

Kanye West picked a desired 15-carat diamond made by famous celebrity jeweller Lorraine Schwartz when he proposed to Kim Kardashian in 2013. The ring has a perfect Type IIa cushion-cut stone with the desirable D color grading.

Kim Kardashian & Kanye West's engagement ring is set on a delicate, exquisite pavé band encrusted with brilliant diamonds. The ring is said to have cost Kanye West up to $4 million (about £3.3 million in today's money). This is a minimal price to pay for an impurity-free Type IIa diamond that ranks among the most chemically pure gemstones. Kanye did well, in a nutshell (for once).

Kim Kardashian received a second engagement ring from West in 2016, which became the focus of public attention after she was stolen the same year at Paris Fashion Week. Robbers held the model and entrepreneur at gunpoint and took jewelry worth an estimated $10 million from her hotel room.

Estimated Cost: $4-$8 million
