Gypsum Crystal in Matrix Triassic Watchet Somerset UK Mineral 30-45mm

Gypsum in Matrix – Triassic Mineral Specimen from Watchet, Somerset (30–45mm)

This Gypsum in Matrix specimen from Watchet, Somerset, UK is a genuine natural mineral piece preserved within its original host rock. Dating to the Triassic period, this specimen offers both mineralogical and geological interest, combining delicate gypsum crystal growth with historic sedimentary matrix. Measuring approximately 30–45mm (full sizing please see photo), each piece is carefully chosen, and the photograph provided shows an example of the actual specimen you will receive. Every item includes a Certificate of Authenticity lifetime guarantee generic card, confirming it as a genuine mineral specimen.

Mineral Species & Chemical Composition

Gypsum is a hydrated calcium sulfate mineral with the chemical formula:

CaSO₄·2H₂O

It crystallises in the monoclinic crystal system and is widely known for forming a variety of crystal habits, including fibrous, tabular, and radiating forms. Gypsum is a classic evaporite mineral, meaning it forms through the evaporation of mineral-rich waters.

Gypsum has a hardness of 2 on the Mohs scale, making it a relatively soft mineral that should be handled carefully to preserve crystal surfaces.

Crystal Habit, Colour & Matrix Features

This specimen displays gypsum crystals naturally embedded within matrix, offering an authentic representation of how the mineral formed in its geological environment. Features may include:

• Pale white to cream gypsum tones

• Subtle translucent crystal edges

• Bladed or tabular crystal growth

• Natural contrast between crystal and sedimentary host rock

• Preserved mineral texture within the matrix

Matrix specimens are especially valued by collectors because they show gypsum in its original growth setting rather than as separated crystals. Each piece is naturally unique in crystal arrangement, matrix colour, and surface detail.

Geological Formation & Triassic Watchet Locality

Watchet, located along the Somerset coast, is known for exposures of Triassic sedimentary rocks. During the Triassic period, around 250–200 million years ago, much of this region experienced arid conditions with inland basins and restricted seas.

Gypsum formed as an evaporite deposit when saline waters evaporated, concentrating dissolved calcium and sulfate ions until gypsum crystallised within sediment layers. Over time, these deposits became lithified into rock, preserving gypsum crystals within their matrix.

Triassic gypsum from Somerset provides valuable insight into ancient evaporitic environments and the climatic conditions of early Mesozoic Britain.

Associated minerals in such evaporite sequences may include anhydrite, halite, and other sulfate-bearing sediments.

Collecting & Traditional Associations

Gypsum has been collected for centuries due to its beautiful crystal habits and importance as a classic evaporite mineral. Specimens preserved in matrix are especially prized for demonstrating natural formation processes.

In spiritual traditions, gypsum is traditionally associated with clarity and reflection; these interpretations are cultural rather than scientific. From a mineralogical perspective, the true appeal lies in its hydrated calcium sulfate composition, Triassic evaporite origin, and preserved crystal growth within matrix.
