Im the kind of guy who looks for alternative materials because I destroy gold and silver chains. I dont know what Sabrina silver does with these Spiga chains, but they are near indestructible. Ive had the 2.3mm sabrina silver spiga chains from before switching to the 5mm for over 4 years. Ive worn it every day and only ever taken it off for a few MRIs and Xrays. The chain has never let me down once over the course of over 4 years. Even the thinner chains are so solid they seem as strong as stainless steel. My 2.3mm spiga chain has been abused more times than I can count. Its been pulled on and pressed on during sports, weightlifting, its been knocked around during heavy bag workouts. Ive had 400 pounds of weight bounced off of it and it barely even tarnished after those years of abuse. In fact, there were times where the only thing I worried about with thee 2.3mm chain was that it was so strong, I could literally choke if it was pulled on hard enough, where other chains would simply break. Additionally this chain has never gotten hung up on anything like many other styles. I love this style of chain and I will only buy from Sabrina Silver.So take all that strength and style and now double it. Thats what you have in the 5mm chain. Additionally its big without looking outlandish or gaudy. The only reason I upgraded was I am wearing a bigger pendant that just made a smaller chain look a bit silly.
