Whether you are looking for a brand-new or second-hand 1 ct diamond ring, eBay offers one of the largest selections available online.

The cheapest option currently starts at $30.99, while premium listings can reach $9500 — giving you a wide budget spread to work with. The average price of $952.83 can serve as a useful benchmark: listings below this tend to be used or auction-style, while those above often include extra accessories, warranties, or are sold by professional sellers with high feedback scores.
