This pearl was exceptional! However, I found 8.0mm to be a little small for a pendant. If you are looking for something dainty and feminine, this is it! Now that I know what 8.0mm looks like, I would order a South Sea Pearl instead. It's a preference thing.
I think it would help if you can go to a store and check out the size of the pearls first. I measured, gauged and viewed a lot of of pictures online of people wearing different sizes of pearls, and it was not too helpful. I even worried that 8mm might be too huge, when I was placing my order.
I will buy from Blue Niles again, because I have seen the quality of their Premier Akoya pearl, and I am impressed.
