Where to find Kambaba Jasper
Madagascar
The primary and most well-known source of Kambaba Jasper, particularly from the Bongolava region.
South Africa
Other stromatolite formations exist in South Africa, some of which may be marketed similarly, though the distinct 'Kambaba' pattern is most associated with Madagascan material.
Other ancient cratons
Stromatolites are found globally in ancient sedimentary sequences, but the specific aesthetic quality and silicification of 'Kambaba Jasper' are less common elsewhere.
Collecting tips
- Look for distinctive patterns. The key identifying feature is the dark green matrix with lighter green, often orbicular or swirling, fossilized stromatolite patterns. Avoid plain green jaspers.
- Check for density and hardness. As a form of jasper (quartz), it should feel dense and be hard enough to scratch glass (Mohs 6.5-7).
- Examine polished surfaces. The intricate patterns are best observed on polished surfaces, which reveal the full beauty of the fossilized microbial structures.
