How does moissanite pricing compare to diamonds of similar size?

I'm so happy, I'm getting married to the most beautiful man in the world. My fiancé wants a diamond engagement ring. I'm torn between diamond and moissanite. I keep seeing crazy price differences. On the one hand, diamonds are forever and all, but honestly, for everyday wear, moissanite looks really similar in terms of sparkle and clarity. I need your help. I'm trying to figure out if it's worth spending 2-3 times more on a diamond when moissanite already looks amazing. Has anyone actually compared them in person? Do you think the price difference is justified when you see them side by side, or is moissanite really good enough to save you money?
