Solitaire Round Cut Yellow Gold Engagement Rings

Timeless and instantly recognizable, the solitaire engagement ring is loved for its clean lines and enduring elegance, cementing its place as the most classic setting style of all. Featuring a single center stone, this classic style allows the gem’s natural beauty and brilliance to shine through. Perfect for those who appreciate minimalism and want to make a statement quietly, solitaire rings suit every diamond shape, from round and oval to princess and pear. They pair beautifully with any precious metal, including yellow gold, rose gold, white gold, or platinum, as well as other colored gemstones such moissanite and sapphire.
