Read the description very carefully. This item is meant for a child -- a very small child -- is absolutely miniscule. Almost a joke but I just did not read carefully enough to understand how incredibly small this is, no larger than my fingernail, my forfinger nail.
I ordered this to match a ring I bought. It is smaller than I thought , but very pretty . The opal has a pretty sparkle to it and the blue topaz side stones are small, but shiney and have good blue color. A bit small, but nice overall.
The opal in the pendant is pretty. The blue topaz and diamonds are not evident. The chain, as usual, is cheap and not worth having. Even when I have purchased much more expensive necklaces, the chains have had to be replaced. The pendant matchs the corresponding earrings well.
I was so sad this was so small and the chain is so thin. If there is diamonds, they are just flecks. If small and delicate is what you want then this would work, otherwise, I wish it was bigger. The opal is pretty though. Thought about sending it back, but it didn't cost much. Can't imagine anyone paying 75 dollars for it, though.
