Purple Chalcedony Points from Madagascar

Chalcedony

Chalcedony is a microcrystalline variety of quartz that occurs in a wide range of colours, with blue, grey and white being the most recognisable. The stone has a waxy luster and is often translucent. Due to its fine structure, chalcedony is widely used in jewellery and decorative objects.

Chalcedony forms in cavities of volcanic rock, where it deposits layer by layer from silica-rich solutions. It occurs worldwide, with important deposits in Turkey, Namibia, Brazil, the United States and India, among others. Its chemical composition is SiO₂ and its hardness is around 6.5 to 7 on the Mohs scale.

Points

Our collection of points includes natural as well as polished and polished specimens, sourced from various countries. We supply points from Madagascar, China, Brazil and India, among others. These differences in origin create distinct variations in shape, finish and appearance.

Madagascar points are generally a bit more substantial in shape, with rounder facets and a more robust look. Chinese points, on the other hand, are tighter and sharper cut, often a bit smaller and with a more refined finish. Both countries usually supply hexagonal shapes. The points from India are usually square in ground shape and slightly less pointed than the variants from China, giving them a character of their own.

Most items have a minimum order of 500 grams. You will receive a selection from the range available at that time. We always select the most beautiful and varied combinations according to our own taste. Please note that sizes may vary per stone type, country and delivery, so the size selection may be wider. We try to indicate this as best we can in the product information.

We have divided the points into the following categories:
