I feel a little bad for people who stumble on this blog searching for things like sf fashion heavy water and heavy water clothing only to find a almost complete lack of deuterium or tritium oxide content. No doubt they leave in disgust, never to return again. So I have decided to put up one modest heavy water posting by way of appeasement.
You can buy jewelry that contains ordinary water or holy water. From the right sources, it is possible to buy D2O, at least in bulk, so by adapting the instructions on how to make a DNA necklace of your own, it should be possible to make a isotopically correct heavy water jewelry, the perfect gift for your own physics geek. Caution, deuterium oxide is reported to be poisonous in large quantities, so don't be swilling the stuff in mixed drinks, despite anything I may have written in the past.
As for tritiated water, you will have to work a little harder because the world demand, the radioactivity, and the proliferation aspects limit worldwide shipments to only about 100 grams annually, so one would be hard-pressed to obtain enough T2O to supply a good-sized jewelry operation. I am not sure it would be a good idea to encapsulate the stuff in a thin layer of glass, because it is something you probably do not want to ingest, any more than one would go around wearing mercury-filled jewelry.
This may be the second scifaiku I ever wrote, back in 1998:

And so the circle is completed.
