Lauren's exact ring is available for $860 online at Neiman Marcus.
Possibly the best look for less is this love script ring available in 14k gold vermeil, rose gold vermeil or sterling silver for $65 at maxandchloe.com.
Another great look for less is this love script ring from t+j Designs. It's $48 and I just so happen to have a coupon code you can use to bring the price down a little bit more! Use coupon code BUDGETBABE at checkout to get 15% off any order for the month of October.
