Style 1: Pavé Diamonds
In the elegant pavé setting, tiny, faceted, fully cut stones are set as close together as possible so you can't see the metal around them (see picture above). Think of it as if the metal band has been paved with diamonds. The pavé look offers bling without being outlandish. We're seeing pavé in metals from yellow gold to platinum.
Style 2: The Vintage Look
What's old is decidedly new this season. The subtle and delicate look of vintage-inspired rings is in. Stones on these rings are recognizable for their Old European round center cut, but you'll also see gorgeous Asscher cuts and others too. The defining details: minimal scroll-like engraving, microset (tiny, half-point) diamonds, delicate milgrain work (raised beaded edges), and filigree.
Style 3: Colored Stones
Canary yellow diamonds, blue and pink sapphires, even rare light pink diamonds are appearing on fourth fingers everywhere. Color can go modern (opt for a tension setting), classic (with a four-prong setting), or vintage (a filigreed setting). Whether you choose your favorite color or your birthstone, a colored stone is a great way to make a stylish statement.
Style 4: Stacked Rings
Two, three, or more bands "stacked" together make a terrific statement. Eternity bands (stones all the way around) look great piled together. Whether your stones are channel set (flush with the metal) or pavé, or even if you just opt for metal bands -- the look is modern and flexible: Wear it with your engagement ring
or without. The best part is that you can start with one and he’ll have anniversary gift possibilities for the next few years.
