That’s a shame about those little baroque freshies, Azra. I think I’ve seen them on the Kong’s Etsy site, and while they’re obviously not the deepest purple, they certainly look darker and appear to have more interesting overtones in her photos.
I’ve bought quite a few bits and pieces from Yunlan, and I find it’s about 20% great pearls, 70% pretty good pearls, and 10% disappointment. I’ve never returned anything, given her generally low prices compared to the cost of postage. I agree with Katbran that it might be salvaging the best pearls from these strands and cutting your losses on the rest. Alternatively, next time you do an order from a vendor with a wide product range, have a look to see if they have anything inexpensive that you could mix in with these to make something fun - some keshi or rosebud pearls in a similar colour might make a pretty, textural rope, or some big nuggets scattered at intervals could be quite casual and fun.
