I can see your halo...ring! If you're rocking a halo ring, please share a picture and how it makes you feel. Traditionally, a halo engagement ring features a frame of smaller stones that surround a larger center stone. Diamonds are the most popular stones used in halo rings, but gemstones are also an option if you're looking for something more unique and colorful. Many love the halo style because of its ability to enlarge the look of the center stone. A high-carat diamond can look even larger, and a smaller stone can look much bigger with a halo. There are a few things to consider with this gorgeous design to find the ring that's right for you.
