I'm the last person in the universe who cares about wearable technology. I had a boyfriend once who kept wearing the watch/calculator from his Bar-Mitzvah way into adulthood, and that has traumatized me for life. But Ringly is bordering on genius. My phone always seems to sink into the very bottom of my purse, and since I keep the ring sound quite low (and forget to dial up when leaving the house), I tend to miss calls and not see texts for hours. This ring connects to one's phone (both iOS and Android). You customize the app to tell it whose calls or texts you want to see, and it vibrates and lights up (there's) a tiny light thing on the side of the band). It can also reminds you of meetings, if you need it to do so. And it's actually pretty.
The one above called Dive Bar is a limited edition rhodium-plated setting and a tourmaline quartz ($195, like most of the line). I think it's my favorite and the one I want most, but I'm also partial to the one below, Into The Woods, is the fanciest (18 karat gold and a real emerald) and is priced at $260.
