Stunning Moissanite Rings! 💍✨
Beautiful rings! I love the United Moissanite settings available on their website. I have about ten moissanite rings along with matching bands because I adore the rainbow effect they give off compared to my mined and lab-grown diamond rings.

Stunning Moissanite & Excellent Service!
I recently purchased a 2-carat loose Moissanite to replace the simulated diamond engagement ring my sweet, unknowing husband bought from another company, thinking it was a lab-grown diamond. Ellen reached out to let me know the 2-carat was out of stock and offered a 2.5-carat at the same price — heck yes, I did! The package arrived quickly,the stone was absolutely beautiful, and my jeweler confirmed it was indeed Moissanite. Now that it’s in my ring, I’ve never been happier. It’s stunning! Thank you, United Moissanite, for making my engagement ring what it was meant to be!
