In archaeology, a petrosphere is the name for any spherical man-made object of any size that is composed of stone. These mainly prehistoric artifacts may have been created and/or selected, but altered in some way to perform their specific function, including carving and painting..

Several classes of petrospheres exist, such as The Diquis Spheres of Costa Rica; painted pebbles from Scotland; stone charms from Scotland; sandstone balls from such sites as Traprain Law; the Carved Stone Balls, which are mainly from Scotland, although they have also been found in Cumbria and Ireland; and carved stone shot for cannons and trebuchets.

The Diquis Spheres

The Diquis Spheres are considered one of the greatest mysteries in the world. What is the story behind the hundreds of massive stone spheres that were accidentally discovered in the 1940s during agricultural activities by the United Fruit Company. They were located on the bed of the Tirraba River, also known as Diquis River, near the towns of Palmar Sur and Palmar Norte in Costa Rica.

Their vast majority is made of granodiorite, a hard, igneous stone taken from the foothills of Talamanca range. Few of them are made of coquina, a hard material similar to limestone. Their diameter ranks from a few centimeters to over two meters, which weigh over 16 tons and they are all nearly perfect in roundness.

Carved Stone Balls

Carved Stone Balls are petrospheres, usually round and rarely oval. They have from 3 to 160 protruding knobs on the surface. Their size is fairly uniform at around 2.75 inches or 7 cm across, they date from the late Neolithic to possibly as late as the Iron Age and are mainly found in Scotland, but also elsewhere in Britain and Ireland. They range from having no ornamentation (apart from the knobs) to extensive and highly varied engraved patterns. A wide range of theories have been produced to explain their use or significance, without any one gaining very wide acceptance.

Nearly all have been found in north-east Scotland, the majority in Aberdeenshire, the fertile land lying to the east of the Grampian Mountains. A similar distribution to that of Pictish symbols led to the early suggestion that Carved Stone Balls are Pictish artefacts. The core distribution also reflects that of the Recumbent stone circles. As objects they are very easy to transport and a few have been found on Iona, Skye, Harris, Uist, Lewis, Arran, Hawick, Wigtownshire and fifteen from Orkney. Outside Scotland examples have been found in Ireland at Ballymena, and in England at Durham, Cumbria, Lowick and Bridlington. The larger (90mm diameter) balls are all from Aberdeenshire, bar one from Newburgh in Fife.

The Towie ball has some design similarities with the carvings on the Folkton Drums. These were found in a tumulus in England and are made of chalk with elaborate carvings, amongst which are distinct oculi or eyes. Concentric carved lines on stone balls appear to be stylized oculi. This ball also has a roughly triangular arrangement of three dots in an interspace between the knobs. This appears to be identical to the arrangement of dots found on the Parkhill silver chain terminal ring, found near Aberdeen, a Pictish artefact. It is possible that the dots represent a name, as some of the Pictish symbols at least are thought to represent personal names.

Kugel Ball

A Kugel Ball is a water feature or sculpture where a sphere sitting in a spherical pocket on a pedestal is supported by a thin film of water. Pressurized water flows beneath the sphere slightly supporting it off the pocket. A kugel ball can weigh thousands of pounds. As the thin film of water suspends and lubricates the ball, it can be spun by hand. Kugel balls are often fabricated from granite. Ring sculptures that rotate on an axis are also built.

This granite kugel ball is located near the Mombasa Island Market inside San Diego Safari Park. It depicts the earth and shows details of its rivers.

World's Largest Flawless Quartz Sphere

The World's Largest Flawless Quartz Sphere is 242,323 carats, weighs 106.75 lbs. (48.5 kg), and measures 12.9 inches (32.7 cm) in diameter. The sphere was cut and polished in China in 1923-1924, and the crystal from which it was cut may have come from Burma. The sphere was a gift of Mrs. Worcester Reed Warner in 1930.
