Let's start with the service: the website says that rings are usually shipped within 4-6 weeks after the order is placed. Well, I wrote an email to them and said I needed the ring within 5 1/2 week. Well, in LESS than 4 weeks, the order was shipped. Their Customer Service team (in my case, I was attended by a guy called Alex) answered all my emails promptly and with helpful information. For a small, independent business, their service is, in my experience, definitely a 10/10. I will order another ring from them as a gift.
As for the ring itself: it is a solid piece of a meteorite, what else has to be said? The pattern raised questions from EVERYONE I sat with, and the obsidian facts really give a nice rough yet crystal-like light reflecting property to it. I was afraid it would get rusty very easily as it is made of iron and thus the pattern would vanish, but that's not the case at all: rust naturally forms around the corners (due to your finger sweating etc), but all you need to do is apply any standard rust remover, brush it off and it's good as new. I recommend you then cover the ring with a thin layer of nail polish: it will protect it from rust AND renew its nice shiny quality! Beautiful ring. Expensive, yes, but 1) it is made from a rock that's been floating on space for LITERAL billions of years, and 2) it is cheaper and MUCH, MUCH more worth its price than your average gold ring out there. Beautiful pattern, comfortable feel (I recommend the liner), good width. 10/10
