This tutorial from MinaevaJA, which is translated from Russian, shows us how to embed air-dry clay flowers in epoxy to create earrings like those shown above and below. At the beginning of the tutorial it says "Part 3"....ignore that. The full tutorial is on this one page. First she shows us how to make a tiny flower with Deco Clay and then, after flower has dried and cured, it is lowered into a mold of epoxy resin and left to set.
The computerized translation to English is full of flaws but the accompanying step-by-step photos should give you enough information to try this unique technique with some of your own mini clay flowers!
