In the field of jewelry, Bulgari and De Beers are both brands with high popularity and reputation. Bulgari is famous for its bold design and unique style, and is favored by royalty and stars. De Beers, on the other hand, mainly absorbs the European century style based on the national conditions and directly faces the high-end market.
Specifically, Prada and Bulgari are not low-grade, but Prada is younger and provides younger products and services. Bulgari is famous for its unique design and style, mainly for the high-end market. De Beers is also an internationally renowned jewelry brand. Although it may not be well-known in China, its advertising slogan "A diamond lasts forever, and an eternal one" is widely known.
To sum up, Bulgari and De Beers are both high-end brands, but which brand is higher needs to be evaluated according to different standards and market positioning.
