Kim Kardashian's engagement ring from Kris Humphries is clocking in at an estimated $2 million.

The 20.5-carat custom-designed piece made a public appearance on Kardashian's finger when she and Humphries were catching an international flight from LAX on Wednesday.

The ring is designed by Lorraine Schwartz.

The platinum ring features a 16.5-carat emerald cut center stone placed between two 2-carat trapezoids. Humphries had the ring designed after a replica of a ring Kardashian had coveted at a young age, according to People.
