POSITIVELight weight.CONCERNSI have been making jewelry and buying “chain bulk” on Amazon. This is the same chain type I buy. I can get card spools of colors of gold, white silver, darker silver, bronze and dark grey for around $10.Clasps like this are the cheapest type of clasp to buy.The pendent gold color looks like it might have been dipped, sprayed or lacquered on. It is shiny.If you are looking for flashy, without longevity, this might be okay. I could see gifting these out at a teen girls party for girls into math or science.I would not give this to a teacher, professor or other adult, as it looks cheap. And to me the longevity seems in question.In US, at mall kiosks or farmer’s market there are jewelry stands. This looks like that type of jewelry quality.For the price, it seems okay.

I am a data scientist and I love wearing my love for math on a chain! This necklace is great quality, super durable, and looks fantastic. I wear it constantly!

I thought this would be a cheap piece of costume jewelry, but it is not. Looks classy and expensive. Nice!

I received this as a gift and it's beautiful! I love it so much and pictures don't even do it justice. It's a thin lightweight metal that is super shiny and of good quality. No sharp edges. Looks classy both close up and far away. It's a nice size and the chain is a good length as well. Honestly I'm considering buying a second one for myself in case it wears out or gets lost. I've worn it several times already and it still looks as nice as the day I got it. Buy it!
