In general, male skulls tend to be larger and more robust than female skulls, which are more gracile. Male skulls typically have more prominent supraorbital ridges, a more prominent glabella, and more prominent temporal lines. Male skulls on average have larger, broader palates, squarer orbits, larger mastoid processes, larger sinuses, and larger occipital condyles than those of females. Male mandibles typically have squarer chins and thicker, rougher muscle attachments than female mandibles.

All of these features vary considerably within human populations, making it difficult to identify the sex of a skull without knowledge of the population from which it came.

Although persons' descents are occasionally stereotyped as different from other ethnic groups on the basis of a variety of traits like eye, hair and skin color, all such characters are not discrete nor preserved in bones.

Among archaeologists and forensic scientists, it is still sometimes stated that the most consistent and unique trait of ancestry in skeleton is skull shape.

Swarovski crystal was first created when Daniel Swarovski invented an automatic cutting machine in 1892. In 1895 the Swarovski company was founded when he established a crystal cutting factory in Wattens. Here he could take advantage of local hydroelectricity for the energy-intensive grinding processes he had patented.

Swarovski crystal contains approximately 32% lead to maximize refraction. The Swarovski Crystal range includes crystal sculptures and miniatures, jewelry and couture, home decor and chandeliers. They also sell beads and rhinestones, encouraging other manufacturers, artists and consumers to create their own designs.

All sculptures are marked with a logo. The original Swarovski logo was an edelweiss flower, but was replaced with the current swan logo in 1988.

In 2004 Swarovski released Xilion, a new copyrighted cut designed to optimise the brilliance of Roses (crystal components with flat backs) and Chatons (diamond cut). Also in 2004, Swarovski created the 9 foot diameter, 550 pound star that tops the Rockefeller Center Christmas Tree in New York City for the first of five consecutive years.
