wife loved it...1 carat per year (married for 30 years) total of 3 carats worked perfectly.

Nice Ring but Not a Great Fit

The ring is very pretty but it did not look great with my engagement ring - it hung over way too much and both together looked awkward. It was also pretty thick so I didn't think it would be comfortable enough for everyday wear. Went with the floating eternity band a LOVE IT!
