Juliana D&E made a number of Egyptian style designs. In a number of them they used different plastic scarab cabochons. Many of these scarab designs can be found in my book Juliana Jewelry - The Last Generation in the Egyptian Revival Chapter.
The most commonly used was done in belts in many different colors. The first photo shows three different belts showing a some of the colors this belt. These scarabs are hollow plastic. I have seen them in pink, topaz, green, and turquoise. However other colors are possible.
The next scarab D&E used was a solid hard plastic design. It has molded accents on the front and the back of the cabochon. I have only seen this in the marbled black/topaz coloration. This scarab was used in a shaped a cut tubing necklace accented with a twisted metal framework. The back of this design is just a pretty as the front.
The third scarab is also a topaz design but it has a different scarab design on it. It was used with a cast Pharaoh with wings. It is also a two sided design.
The final scarab design is a new one found when the collection from Mr DeLizza's factory came out. It is a multi-colored scarab in a much smaller size than the others so suitable for earrings. Finding these earrings makes a person wonder if the other designs also could have had earrings done in this smaller sized cabochon. It also a two sided design.
All of these scarab designs can also be found in the online database of confirmed Juliana Jewelry http://isitjulianajewelry.com/
