I’m highly allergic to anything other than gold and silver and this necklace didn’t disappoint. I got the 16’ length and next time I’ll purchase the 18’. My concern is that shipping should’ve been certified, additionally insured, and with a signature because it came through regular USPS mail. Luckily, I have a safe deposit mail box with my association and it was placed in there until I picked it up. Considering that I paid more than 300 dollars and that regular mail only covers 50 dollars without certification and without additional insurance. I would’ve been at a loss if I lost my package. Which happened before with USPS with an order I had with another company. However, I’m please with the fast delivery and item. Thank you.
