And I think pearls do even worse on the secondary market than other jewelry for a variety of reasons!Hmm...I would think any established, reputable brand would hold it's value but beware most jewellery does not increase in value as such unless it's exceptional (ie. natural sea pearls, or has special famous provenance etc)
i am available for adoptionI never make a jewelry purchase and think about resale. I have kept everything I have bought and as each piece was selectively chosen and I would be hard pressed to sell any of my pieces. I do not have many pieces so what I have I plan to keep and pass down to my daughters.
