There's no doubt that Gwen Stefani has received some serious bling since she began dating Blake Shelton. In 2017, Shelton spoiled Stefani with a diamond Cartier necklace worth more than $60,000.
When she turned 51, Shelton gifted her another flawless diamond necklace shaped as the number five to represent the years they had been together. From jewelry to real-estate, Shelton then casually dropped $13 million in 2020 on a Californian mansion for Stefani so she could spend more time in her home state.
