Alexandrite's changing appearance only adds to the appeal of this Gemstone Engagement ring.

Radiant Lab Diamond with Sapphire Accents - Gemstone Engagement Ring

A radiant lab diamond gets a colorful update with blue sapphire baguettes on either side. The rectangular sapphires create a crisp frame around the center stone, while the white gold setting keeps everything looking clean and polished. If you love the brilliance of a diamond but want more color in the design, this colored lab diamond engagement ring delivers a beautiful balance between classic and unexpected.

Choosing the Right Colored Engagement Ring

With so many possibilities, start by thinking about what you want the center stone to say. A sapphire brings rich color and a timeless feel, while tourmaline opens the door to pinks, oranges, and other unexpected shades. Moonstone and moss agate have a softer, more natural appearance, while alexandrite and parti sapphire add changing colors that make the ring look different depending on the light.

Then consider the shape. A classic oval or radiant cut will have a familiar engagement-ring feel, while kite, hexagon, and geometric cuts can make the piece feel much more contemporary. The setting also changes the overall look. A bezel setting creates a smooth, streamlined profile, and the prongs put more emphasis on the stone itself.

Don't overlook the details that make a ring personal, either. Engraving, birthstones, meaningful motifs, and custom stone selections can turn an already beautiful piece into something that belongs to one love story.

That's ultimately what makes a gemstone engagement ring or colored lab diamond engagement ring so special. There isn't one right way to design one. The best choice is the ring that feels like it belongs to the person who will wear it, and these Rosalee Jewelry designs give you plenty of ways to make that happen.
