Getting engaged is a life event that's long awaited by both men, women and in-laws alike, so shopping for an engagement ring is a monumental task that shouldn't be taken lightly, no matter who's in charge of choosing the bling. Browsing for a shiny new bauble sounds much easier than it actually is, of course, since one has to consider the 4 C's (cut, color, clarity, and carat weight) and the fact that an engagement ring is a significant expense.

Color, clarity, carat and cost aside, a diamond's cut (or shape) is of considerable importance because it's the one detail that determines a ring's sparkle. Cuts vary in style from emerald to asscher, but the diamond pros at Blue Nile recently revealed that one specific shape continues to remain a top choice among recently engaged couples. The clear-cut winner: Round diamonds.

According to the largest online retailer of certified diamonds and fine jewelry, 66% of all U.S. orders are round-cut diamonds. The most preferred metal is platinum, with 42% of sales nationwide, while solitaires continue to trend as the most popular ring setting of all.

The study went on to reveal popularized diamond trends throughout the country; specifically how baubles stack up from state to state. New York City couples frequently opt for pear-shaped diamonds, while Blue Nile buying info shows that Dallas brides order the most emerald-cut rings. Rose gold rings continue to trend, and the hue is especially preferred among Atlanta-based to-be-weds.

Size matters for ring-shoppers in Charleston; the city is home to the biggest rock—an 8.04 carat princess-cut diamond purchased within the past year. As for the largest heart-shaped diamond purchase? Honolulu lays claim to that title with a 4-carat ring.
