This combination of Serandite and Aegirine from Poudrette Quarry, Mont Saint-Hilaire (MSH), Quebec, is considered one of Canada's classic mineral associations. Renowned for its extraordinary mineral diversity, this quarry has produced some of the world's finest specimens of both minerals. Serandite forms beautiful salmon-pink to orange-pink prismatic crystals, while Aegirine grows as glossy black, often sharply terminated blades, that may occur individually or in radiating sprays. These minerals are often accompanied by white Albite or Analcime, producing beautiful specimens.
Serandite is the signature mineral of Mont Saint-Hilaire and is the most sought-after species coming from that locality. This beautiful crystal cluster would be a great addition to any new or existing collection.

This is an incredible green/yellow fluorapatite crystal from Cerro del Mercado (Iron Mountain) at Durango, Mexico. It is completely free of the matrix and has a relatively perfect termination. The specimen came from the Earl Calvert Collection.
At Cerro de Mercado numerous veins containing gemmy, lemon-yellow to greenish fluorapatite crystals cut through the hematite massif. These crystals have been collected for decades from the area's iron mines, but they have become much scarcer with recent mechanization of the mining operations.
The bright, lustrous apatite crystals form hexagonal shapes with off-center terminations. They are found in vugs, often associated with quartz and calcite. Most crystals are around an inch in length, though larger crystals up to about 4 inches long have been found.

Heulandite is one of the most common and well known members of the Zeolite Group. It has a nice pearly luster and lovely colored hues. It forms wonderfully complex and quite unique crystals and is often associated with other rare and beautiful minerals.
Green heulandite is a naturally occurring and is prized for its vibrant green color, glassy luster and well-formed tabular crystals. Found primarily in the basalt cavities of the Deccan Traps in Maharashtra, its distinctive green hue is typically caused by microscopic inclusions of the mineral celadonite rather than the heulandite itself. It commonly occurs alongside minerals such as apophyllite and stilbite.
