I'm thinking about asking for a birthstone ring for my birthday. A Two Birch advertisement popped up on facebook and the site has great review, free shipping and they can customize any ring on their site to include birth stones.

I got a quote from them to add two birthstones to this ring. Since the babies have the same stone, I'm picking amethyst and peridot stones and alternating it on the ring. Price isn't that bad. Plus, they have this Perfect Fit feature where they send you a mold kit and you can send them a mold of your ring. Then you can see it in different ring designs and I think they can make the ring fit perfectly with your existing rings.

Side note: Anyone use Two Birch before?
