This is the DNA Ring Collection available from Takayas Custom Jewelry. The bands look like double helixes and are available in sterling silver, 14K gold, 18K gold, platinum, and the woman's ring is accented with diamonds. You have to contact them for prices. I'd do it for you, but I'm not your wedding planner. I mean, unless you want me to be. My rates are fair and I've never not thrown a VERY memorable wedding. Just ask any of my previous clients. "The cops got called and everybody got arrested." Except her, don't ask her, she was a bridezilla. Ask somebody else. "The reception hall caught fire and two dozen family members had to go to the hospital for smoke inhalation." But that indoor fireworks show was amazing, was it not? A night to remember. Sorry about your grandma though, seriously.
Keep going for a couple more shots.
