Brilliant Earth

Brilliant Earth’s gemstone engagement ring section covers a wide range of coloured stones: blue, pink, yellow, and padparadscha sapphires, emeralds, rubies, morganites, aquamarines, and alexandrites. All can be paired with their standard engagement ring settings, and the site lets you filter by stone type, shape, and colour before selecting a setting.

Sourcing information for each stone is provided where available, which suits buyers who care about the origin of their gemstone as much as its appearance. International shipping to Switzerland is free via FedEx, with two-to-five business day delivery after dispatch. The 30-day return window and complimentary first-year resize apply to gemstone rings as well as their diamond range.
