She's selling these TAHITIAN PEARL STUD EARRINGS for $399, without any guarantee, proof of origin or return policy, and I just found Macy's selling the same studs for $300, Pearl Paraside's selling for $290, Pure Pearls for $299, The Pearl Source for $169 or $199 according to the model, American Pearl for $110, Nordstrom for $79. What makes her pearls so expensive? More expensive than real brands with real stores and everything?
And for real, there are so many online courses on jewelry making, gemstones and fine design. If she really wants to make a name for herself as a jewelry maker, she could at the very least study more and put some credentials on, instead of only saying she made an apprenticeship when she was younger. We're in a pandemic, if you have income and a job and some free time, it's a great time to improve your skills - and as a jewelry maker, that would be some nice thing for her to talk about in videos, on instagram and even to put on her linkedin.
I wouldn't spend all that money on a supposed jewelry maker who only studied a bit a couple years ago and now sells some overpriced dubious quality stuff - there's people on Etsy with way more credentials than her, selling better things with more reasonable prices. If she had working selling fine jewelry, she would already have more credentials than simply that apprenticeship - a friend of mine did this, worked for years as a fine jewelry seller in a reputable store and went on to study jewelry making and gemstones. She now makes jewelry for brides and has a great reputation in town as someone who studied a lot and who makes great quality pieces. She's very clear about the metals and gems she uses, has a return policy and definitely has pieces that are heirloom quality (she recently made some pieces for a young bride that used her pieces on her sweet sixteen birthday).
