This is my DNA heart ring design. What's unique about this design is that I made the helix conform to a tighter spiral than what is commonly seen. I think this looks much more appealing. Technically, this is a diagrammatic representation of a deoxyribonucleic acid molecule made into the form of a ring. More specifically, it is a representation of normal B-DNA having a right-handed helix as first described by Watson and Crick based on Rosalind Franklin's X-ray diffraction images. This Amazon Handmade listing is for sterling silver, however I can make it in other metals too, just let me know what metal you want and the size and I'll quote you a price. Also, I can make it in any size in addition to the sizes listed in the drop down list above; quarter sizes, larger, smaller, etcetera. White ring display box and gift wrapping box included. Do you have any science jewelry ideas? If so, let me know!
