The opals in these earrings are pretty and a good size. The blue topaz and diamonds are not evident. If it was not advertised that they were there, you would never know it. Still, I purchased the earrings for the opals and not the blue topaz and diamonds mentioned; so am not bothered by them not being evident.
Really like the style of these earrings. I bought them for my mom and I am buying one for myself now. The diamonds are crap but the blue stones are pretty even though they are light. The opals are very pretty and the style are very classy and antique looking.
