Truthfully speaking, I think the cost of this is a little absurdly high, in general it's something you could make yourself for much less given the material costs. But it looks very nice and is certainly packaged up nicely for gifting. The beads are a bit chonkier than I expected, and I have a 6.0 inch wrist so it's just slightly overly large for me but it looks great paired with a large watch, which can keep it higher up on my arm. The rich stone pigmentation is nice and attractive.
The long list of stuff you're not supposed to expose the bracelet to makes it obvious you can expect to see rusting and tarnishing over time (although I think some of these details apply specifically to other items this company sells and not the blue stone). The bracelet came vacuum-sealed as well. I've never had a dumortiertite bracelet before, so I'm not sure what to expect. Dumortiertite quartz is a denim blue stone, often used as a cheaper substitute for lapis lazuli despite being somewhat rare itself, which is said to represent insight, self-reliance, and patience/emotional balance, and aiding you to remember your dreams better and greater intuition in the daytime. So I thought it seems well suited for me. It has Mohs 7 hardness so it is decently hardy. The elastic string does not seem too flimsy so far. A nice gift for a older students and entrepreneur types, in particular.
