Brilliant Earth vs Rare Carat:
Compare before you buy

Yes. Rare Carat is an online diamond retailer with 100,000+ GIA and IGI certified diamonds, free 24/7 advice from GIA-graduate gemologists, and free shipping with 30-day returns. Because Rare Carat operates entirely online, with no physical showrooms to staff or stock — the overhead is lower, and those savings get passed on to you in the form of lower diamond prices.
