If you're the Link to her Zelda, look no further than Takayas Jewelry's Legend of Zelda Wedding Collection. For a love as strong as the Triforce, choose these white and yellow gold rings with diamonds featuring the Hyrule Royal Crests. The men's version has the Hylian Shield decorating the band.
We actually witnessed a proposal at the Zelda Symphony earlier this Summer. If only the groom knew of this Hylian jewelry to complete his geek engagement! For pricing, inquire on Takayas Jewelry's website.
