My initial order (grey necklace) was out of stock so the seller contacted me on multiple platforms to get my preferred alternate colour for the chain. He even gave me a choice of pendant colour, so I got the grey pendant with the black chain. Thank you seller! The necklace is nice, just that the clasp is not very sturdy and the necklace pendant has actually dropped out while I was wearing it. Ionic effect is present I think, but it feels lower than my other ionic necklace. Overall still a buy that I don't regret!
