This is a great ring by Bloom Studios. The jeweler describes it as looking like the ocean with the dendrite inclusions forming tiny seaweed and it definitely does look like that.
I love the simple but elegant feel to all of Bloom Studios jewels. Also on Bloom Studios is this lovely “opalized conchina” pendant.
You can find Bloom Studios on Flickr and Etsy. It was also nice to note that Bloom Studios donates a portion of their profits to nonprofits.
