Suncoast Gem Lab Competitors

At GIA, we believe every gem has a story — formed deep within the earth and revealed through science. For nearly 100 years, we’ve been bringing those stories to light through research, discovery and education. As a nonprofit, our mission is to ensure confidence in gems and jewelry by blending innovation, knowledge and science. From creating the 4Cs of diamond quality to inventing tools used worldwide, we make learning an adventure and turn discovery into truth. We don’t buy, sell or appraise gems. Instead, we provide trusted reports, education, and insights that help people — from industry professionals to everyday consumers — make informed decisions with clarity. This is GIA: where curiosity fuels innovation, knowledge builds confidence and science inspires a world of trust.

Brilliant Earth was founded by Beth Gerstein and Eric Grossberg as a response to the lack of transparency and irresponsible mining practices that confront the jewelry industry today. Brilliant Earth began with the belief that exceptional quality, ethically sourced jewelry can be an effective tool for social change. From our award-winning jewelry designs and responsibly sourced materials, to our personalized showroom experience, customers never need to compromise between quality and conscience. Brilliant Earth makes jewelry you can feel good about wearing with thoughtful craftmanship in every phase of production. With our Beyond Conflict Free™ diamonds and commitment to social and environmental responsibility, we hope to inspire a more transparent, sustainable, compassionate, and inclusive jewelry industry. Brilliant Earth is one of the fastest growing ecommerce jewelers in the world, and a leader in ethical origin fine jewelry. We are on the lookout for bright, motivated candidates who are eager to make an impact from day one and grow with a team of passionate and kind people!
