A 1cm scale cube is included to give an accurate sense of size, and full measurements are available in the accompanying images. Every specimen is supplied with a Certificate of Authenticity, ensuring complete confidence in its natural origin and mineralogical integrity. Madagascar is globally respected for producing exceptional-quality Carnelian, known for its warmth, depth of colour, and distinctive patterns formed during geological processes.

Geology and Formation of Carnelian

Carnelian is a reddish-orange variety of chalcedony, a microcrystalline form of quartz composed primarily of silicon dioxide (SiO₂). Its unmistakable colour comes from iron oxide impurities within the silica structure. Over millions of years, silica-rich fluids permeate volcanic and sedimentary rocks, gradually forming chalcedony in cavities and fissures. Iron-bearing minerals present during this process undergo oxidation, intensifying the orange-red tones that define Carnelian. Madagascar’s unique geological history—marked by ancient volcanic activity, tectonic uplift, and silica-saturated environments—provides the ideal conditions for high-grade Carnelian to form. As a result, specimens from this region often exhibit deep colour saturation, intricate internal banding, and excellent structural uniformity.

Mineral Characteristics and Crystal Structure

As a member of the chalcedony family, Carnelian belongs to the trigonal crystal system, but instead of forming distinct crystal faces, it develops as microcrystalline aggregates. These tightly intergrown crystals give Carnelian its smooth texture, waxy lustre, and ability to be polished into spheres with exceptional sheen. The specimen may display semi-translucent to opaque areas, with light often glowing warmly through thinner zones. Colour variations may include fiery orange, softer apricot, red-brown, and honey-like tones. Some spheres exhibit subtle banding or cloud-like internal patterns typical of chalcedony, adding visual depth and making each piece truly unique. When polished, Carnelian frequently shows a glassy surface with natural internal veils or inclusions that contribute to its character.

Locality Significance: Carnelian from Madagascar

Madagascar is particularly renowned for its deposits of chalcedony and agate, producing Carnelian with exceptional clarity and vibrancy. The island’s mineral-rich landscapes are shaped by ancient geological processes that foster the development of diverse quartz varieties. Carnelian sourced from Madagascar is known for its consistent colour quality, durability, and strong aesthetic appeal. These geological conditions also promote the presence of associated minerals such as agate layers, jasper bands, and subtle druzy formations within chalcedony nodules, contributing to the distinctiveness of each specimen. Collectors and crystal enthusiasts value Madagascan Carnelian both for its beauty and for the reliability of its natural characteristics.
