A new project was created to ultra-personalize your jewelry by adding DNA from a loved one. The inspiration came form a Swiss chemist, Robert Grass where he works to develop a technology to stabilize and store DNA. He quotes, "Our DNA is what makes us unique, and with jewelry, it's something that you want to be unique and special."
It's done by collecting saliva samples by using a cotton swab on the inside of the cheek. The sample is processed and the DNA is extracted and purified. Then the scientists add chemicals to the liquid solution containing the DNA where it's "fossilized". It ends up being a powdered glass containing all the DNA strands where it's embedded into a piece of jewelry.
The DNA is unharmed and if needed to, the sample can be recovered at any time for other types of analysis. The scientists also found that the DA would decay to half of its concentration over the course of 1,000 years.
I think that this is actually a really cool finding and it's also a super interesting process of how they get the DNA preserved. I know that there are other things like this when people pass away and are cremated, they can be put into jewelry as well. This is a totally new way to do that and honestly I'd probably get something like this one day.
