12FIFTEEN is an engagement jewelry company in the Forever Companies group. None of us use mined stones in our jewelry. Why? Because it’s just not necessary. It is, however, necessary to give great customer service, assemble our jewelry in the Americas, and make sure every piece is over-the-top quality.
Forever Artisans, our design studio and production house, makes all the rings on this site and can make anything you want. For instance, say you like one of our solitaires but wish it had two cute side stones. You got it! They’re master craftspeople. They make amazing custom fine jewelry as well, including earrings, necklaces, bracelets and all sorts of imaginative funkiness. These are the peeps. Really, they’re fine jewelry ninjas.
Diamond Nexus offers fine jewelry with patented diamond simulants that are the best in the industry. Diamond Nexus also offers lab grown rubies, emeralds and sapphires that are chemically identical to their mined counterparts. Diamond Nexus is for people with expensive tastes who have better uses for their cash. Nexus stones are awesome.
