The jewels: Madison Beer’s engagement ring features an extremely elongated cushion cut center diamond in what appears to be a fairly simple setting. As for the ring’s value, Kothari gave a wide range: “If it is a natural diamond, I would estimate a retail value starting around $400,000. Only Natural Diamonds said on Instagram that the ring looks like a “10-12 carat extra elongated cushion cut natural diamond set solitaire on a platinum band.” The trends: This ring hits several major trends that were already doing quite well: vintage inspired rings, elongated diamonds, and antique/unusual center stones. It’s easy to see this ring as a stylistic successor toTaylor Swift’s extremely popular ring from last year, which also features an elongated diamond in a solitaire setting.
