Our bildhau stones are natural stones in individual shapes & sizes, the dimensions & weights of which we cannot specify exactly in advance. You can choose your stone from different weight categories, in which the maximum price for a stone of the respective category is indicated. The stone supplied will be individually weighed and charged at the price per kilo stated here. The price charged will be lower than the maximum price of the respective category.
It is important to us that you receive exactly the material you need for your project. If you are looking for a stone with more specific dimensions (e.g. elongated, approx. 30 cm), please let us know in the message field at the end of the order process. We will endeavour to find a suitable stone for you. On request, we will send you a photo in advance for inspection. We charge a service fee of 9.50 euros for this service, which will be shown on the invoice.
Larger stones and cut-to-size pieces are generally also available for many types of stone. Please contact us by e-mail or telephone for a binding quotation.

The rarer Leopard Stone has a strong yellow-greenish colour. Due to its open structure and varying density and hardness, processing it can present challenges.
TECHNICAL SPECIFICATIONS
| Origin: Zimbabwe | Zimbabwe |
| Degree of hardness Mohs | 2,5 - 3,5 |
| Appearance | strong greenish-yellow, layered |
| Structure | very fragile, partly loose and open |
| Density | 2.5 - 2.8 kg/dm³ |
PROCESSING
Leopard Stone can have a very different structure. If it has a very dense, firm structure, it can be worked well with forged steel chisels such as point chisels, claw chisels, flat chisels and lettering chisels, and even better with carbide chisels, especially carbide pointed chisels. Rasps and files can also be used. Harder serpentine can be worked well with diamond rasps.
Machining is also possible. However, it is important to ensure that the speed of the angle grinder is not set too high, as the dust of the Leopard Stone is 'sticky' and the angle grinder can then get stuck. A fine dust mask should always be worn during machining.
Disturbing cracks can easily be filled and fixed with very liquid super glue before machining. Visually, the filling is hardly noticeable due to the layering and pattern of the leopard stone.
Leopard Stone has a low resistance to weathering, so sculptures made of Leopard Stone are suitable for indoor installation.
FURTHER INFORMATION
At bildhau we sell serpentine stones from Zimbabwe. Most serpentine stones are quarried there on the edge of the "Great Dyke", a magmatite body around 550 km long and 4 to 11 kilometres wide, which is rich in minerals and ores. The serpentine sourced from bildhau in Zimbabwe is quarried and traded fairly in cooperation with the local population.
The name serpentine for the stone is not entirely correct; the rock is actually serpentinite. Serpentinites have formed from serpentine minerals (e.g. lizardite, antigorite, chrysotile). In some cases, they also contain other minerals such as olivine, pyro-rich garnet, bronzite or diopside-rich pyroxene, from which the serpentine minerals originally formed. A red colour is caused by haematite (iron oxide). Serpentinite often also contains magnetite. Serpentinite is a metamorphic rock that has formed on the (former) seabed as a result of high pressure and temperatures, among other things.
Stone is a natural product. We endeavour to reproduce the appearance of our sculptured stones as accurately as possible in the illustrations so that the character of the stone can be recognised. Ultimately, each stone is unique and the appearance may differ from the illustration.
