I am pleased to offer this authentic carbonaceous chondrite – NWA 18528, an officially classified CM2 meteorite, discovered in Algeria in 2025.

This exceptional specimen belongs to one of the most scientifically important groups of meteorites, representing some of the most primitive material formed in the early Solar System.

Despite its small size, this piece carries extraordinary scientific and collector value, being part of a very limited total known mass.

--- Scientific Background ---

NWA 18528 is classified as a CM2 carbonaceous chondrite, a rare class of meteorites known for their primitive composition and high scientific importance.

These meteorites are rich in:

Fine-grained black matrix
White chondrules (~8%)
Calcium-Aluminum-rich inclusions (CAIs)
Hydrated minerals (phyllosilicates)

CM2 meteorites are particularly significant as they are believed to contain water-altered minerals and organic compounds, offering insights into the early Solar System and possibly the origin of water on Earth.

--- Description ---

This specimen exhibits a deep black matrix, characteristic of CM2 meteorites, with subtle textural variations and remnants of fusion crust.

Its extremely small total known mass (only 24.2 grams) makes each fragment exceptionally rare and desirable.

Presented in a refined frame, this piece becomes both a scientific specimen and a unique display object.

--- Rarity ---

Only a limited number of CM2 meteorites are officially classified, and specimens with such a low total known mass are extremely scarce on the market.

--- History & Provenance ---

The meteorite was purchased in 2025 by Patrice BACHELIER from a meteorite dealer in Algeria and later classified and published in the Meteoritical Bulletin.

The main mass and remaining material are held in part within curated collections, ensuring traceability and authenticity.
