Sorry the chain is not 925 silver it doesn't say on the chain so I doubt that it's plated its a nice change but I don't think that it is real silver thank you for asking
The quartz crystal is a little over an inch long the metal wrapping I haven't had one that has tarnished on me but even 9.25 silver may tarnish over time so it could possibly the chain hasn't turnished on me but it does depend on the person and alkaline oils in their body if you're a person that can't wear anything other than real silver or gold it could do that to your skin
Very informative, thank you. I wear gem stone rings and stainless steal with no affects of it leaving green marks on my skin. I should be find then, thank you again.
