Brilliant Earth is a fine jewelry company that sells engagement rings, wedding bands, and gemstone jewelry through direct-to-consumer channels and physical showrooms. The brand specializes in diamonds and gemstones traced to responsible origins, offering both natural and lab-grown diamonds alongside alternative stones like moissanite, sapphire, and emerald.

Founded in 2005, Brilliant Earth was built on the conviction that ethical sourcing and supply chain transparency could become standard in fine jewelry rather than a niche concern. The company challenged the opacity that had long defined the industry by making diamond provenance and responsible sourcing central to its business model.

Now publicly traded, Brilliant Earth has established itself as a category leader in ethical fine jewelry. The brand emphasizes transparency in its sourcing practices, uses repurposed gold in its designs, and offers customization options across a range of styles and stone types, from vintage-inspired settings to contemporary designs.
