I prefer unbranded although I own both. I don't resell anything and don't plan to so I don't care how much resale value my collection has. I buy rarely and with a lot of thought, so I have no interest in letting go of any pieces in my collection, many of which I've been wearing since I was a teenager (I'm 29 now). Quite a few large, heavy gold pieces I have inherited, so they have a lot of sentimental value.
I often browse brand name pieces on
Fashionphile (I prefer to buy secondhand if brand name to avoid markups a little), and Etsy. I really don't like how so many designer jewelry pieces have large logos. There's no creativity or originality to this kind of design. I'm curious as to what other posters in this thread are buying, in particular the ones that have said unbranded jewelry looks generic, whereas brand name looks original. I also find a lot of the popular pieces that are easy to find on secondhand sites are not for me, such as the love bracelet, the JUC, the RTT stuff, etc. The only brand name item currently on my wishlist is the YG Tiffany hardwear necklace.
This brand doesn't get mentioned often on this site, but I love BVLA pieces. They're high quality, and the designs are absolutely stunning. I find the pricing reasonable, and there are so many pieces I love that I find it difficult to pick just one.
