Has anyone ever bought one of these candles? They are called dimond candles. They have rings in them and when they melt you get the ring lol I think that is pretty neat even though I would probably be very impatient waiting to get the ring lol i think it would be a nice gift to give my mom and sisters for Valentine's day because I love them very much lol
