Grade A Opalised Marcasite Crystal Miocene Indonesia Backlit Colour Translucence Mineral Specimen

Description

OPALISED MARCASITE CRYSTAL SPECIMEN

This listing is for a Grade A Opalised Marcasite crystal specimen identified with a Miocene designation and associated with Indonesia. The specimen is presented as a natural geological collecting piece, with its opalised marcasite identification making it suitable for mineral collections, educational displays, cabinet presentation and decorative use.

APPEARANCE AND PHOTOGRAPHY

The product name highlights colour and translucence, particularly when viewed with backlighting. Backlighting can help reveal the way light passes through or interacts with translucent areas, making the specimen especially suitable for close observation and display photography. Natural mineral specimens can show variation in surface appearance, internal character and light response, so the photographs are an important part of this individual listing.

The photograph shows the actual specimen you will receive.

GEOLOGICAL IDENTIFICATION

Marcasite is a recognised iron sulphide mineral, and “opalised” describes the identification supplied for this specimen. The additional Miocene designation refers to a geological time classification associated with the piece. Miocene rocks and mineral-bearing environments are part of Earth’s comparatively recent geological history, making this specimen an interesting addition for collectors who organise material by geological age as well as by mineral identification.

No formation description is supplied with the specimen, so the focus remains on the stated identification, locality and visible appearance. This makes the piece appropriate for mineral enthusiasts, geology students, classroom or study displays, and collectors seeking an opalised marcasite specimen from Indonesia.

LOCALITY

The stated locality is Mount Cidolog, Pasanggrahan, Sagaranten, Sukabumi Regency, West Java, Indonesia. This locality information gives the specimen a specific geographic collecting context and can be used when cataloguing or arranging a regional mineral collection. The Indonesian origin, West Java setting and Miocene designation together provide useful reference points for a display label or collection record.

COLLECTING AND DISPLAY

Opalised marcasite is an appealing choice for collectors interested in unusual mineral identifications, natural translucence and specimens that show different visual qualities under direct and backlit illumination. It may be displayed in a mineral cabinet, on a desk, in a geology classroom, or as part of a curated collection of Indonesian minerals. Its colour response and translucence also make it suitable for collectors who enjoy photographing specimens under varied lighting conditions.

The specimen can be considered for birthdays, geology-themed gifts, mineral collecting gifts and educational presentations. It is also a distinctive decorative object for anyone who appreciates natural geological material and the visual character of individually photographed specimens.
