A few of the things I've made with Sculpey Premo Polymer Clay
This is a large natural quartz crystal point, which I have set in white Premo clay. First I molded the clay around the crystal then carved a feather shape in clay and attached them. It gets baked in my dedicated  clay oven at 275 degrees F (135 C) which hardens the clay but does not affect  the crystal. After it's cool I give the clay a brown antique wash which results in an aged clay appearance.
This is a Mayan Calendar wall plaque. First I created a thick round base, then I carved out the glyphs and embedded various gemstones for each time period. The sun rays at the center reach out and touch each gemstone. I chose the gemstones for each glyph based on what I had available to me and matched them up with what I knew about the meaning of each glypyh and its characteristics. So this is not exact science but my artistic expression of it. This piece took about a week from start to finish and was one of my favorite things to work on.
This is a small wall plaque with my rendition of the Sephiroth of the Kabbalah. I started with plain white clay, embedded colored glass cabochons and carved out the symbols. Finally I antiqued it with a wash of brown acrylic to make it look like an ancient clay tablet.
This is the back side of a round mirror that I removed from an old compact of Maybelline face powder. It has an amber glass cabochon in sun rays over an Egyptian hieroglyph background.
This example shows the bare white Premo clay before and after finishing. After curing the clay I painted it with alcohol inks and acrylic paint and gave it a final bake to set the paint. This one is holding a Sodalite gemstone.
This pendant holds a Prehnite gemstone set in brown Sculpey III  clay, and embellished with other pre-colored clay in greens and browns.
This is a quartz crystal point set in black Premo clay, and finished with Rub 'n Buff Metallic Silver Leaf. This is an example of reverse-antiquing; the color is on the raised portions of the clay and recessed areas remain black, resulting in an oxidized silver look.
This ring holder was made by molding white Premo clay around an empty can of chopped New Mexico green chiles while baking and cooling. (Being in Lubbock, Texas, we are big fans of Hatch Chile, which is grown and roasted by our good neighbors in Hatch Valley, New Mexico.)
This little jewelry box was also made by molding the clay around a small can.
I handmade a custom hinge for the lid out of silver, gold and copper colored wire.
I decorated the outside of the jewelry box with celtic knotwork designs and Norse runes on the back
Another ringholder made by molding plain white Premo clay on an empty Hatch chile can. These get baked on the can to hold the shape. Then more clay elements are added for decoration, another bake, cool, adding brown acrylic paint to antique it.
This pendant was made using multiple shades of brown clay. A turquoise cabochon is inset in the center.
This is a Labradorite cabochon set in brown clay which was shaped, carved and finally antiqued in a black acrylic wash.
These pendants were made by setting Turquoise stones in white clay then finishing with a brown antique wash.
This is a Quartz Crystal point with New Zealand Paua (abalone) shell set in Premo copper clay.

"Copper clay" gets its look from pigment dyes and mica powder; it does not contain any copper metal in it.

These big hole beads are made by molding the clay around a metal rod then decorated. I started with white Premo clay, and antiqued them with a brown acrylic paint after they were fired in the oven and cooled.
This piece started with a white clay base and then adding decorative elements that I made from precolored Premo clay. It is my rendition of the sea floor; with little barnacles and shells and other sea creatures. There is a tiny quartz crystal point cluster embedded in the center.
