Half of U.S. engagement ring shoppers in 2024 favored a 0.5–0.69 carat center stone, yet the average ring price climbed to $5,500 in 2023, up from $4,700 the year before. At the same time, global diamond jewelry sales are forecast to hit $87.6 billion by 2027 while polished diamond prices fell year over year in 2023, hinting at a market where demand is steady but costs are anything but. Let’s connect the dots across preferences, pricing pressure, and supply chain signals.
