Grade A Opalised Marcasite Crystal Specimen Indonesia Miocene Backlit Colour Gem | Mount Cidolog, Sukabumi Regency, West Java

Description

Grade A Opalised Marcasite Crystal

This Grade A opalised marcasite crystal specimen is identified with a Miocene designation and associated with Mount Cidolog, Pasanggrahan, Sagaranten, Sukabumi Regency, West Java, Indonesia. Its presentation combines the distinctive subject of marcasite with opalised character, making it an appealing addition to a mineral collection, geological display or carefully arranged crystal cabinet. The backlit photography is especially useful for viewing the specimen’s colour effects and translucence.

Appearance and Display

The specimen is presented as a natural geological object rather than a manufactured decorative piece. Backlighting brings attention to visual features that may be less apparent under ordinary illumination, including colour variation and the way light passes through or interacts with parts of the material. This makes it suitable for display near a lightbox, illuminated cabinet or other controlled backlit setting where its photographic highlights can be appreciated.

The title “opalised marcasite” describes the supplied identification and presentation of this specimen. Marcasite is an iron sulphide mineral recognised in mineralogy as a polymorph of pyrite, with the same chemical composition but a different crystal structure. Marcasite is commonly discussed in relation to its metallic lustre and crystalline character. The opalised description adds an important visual and material aspect to this particular specimen, distinguishing it from a conventional marcasite display piece.

Geological Identification

The supplied additional identification is Miocene. The Miocene is a recognised epoch within the Neogene Period of the Cenozoic Era, and this classification provides geological context for the specimen listing. The stated locality is Mount Cidolog, Pasanggrahan, Sagaranten, Sukabumi Regency, West Java, Indonesia. Locality information is an important part of mineral collecting because it connects a specimen with a specific geographic setting and helps place it within a broader study of regional geology.

Collecting and Gifting

This specimen is well suited to collectors interested in marcasite, opalised minerals, Indonesian geological material or Miocene-labelled specimens. It can also be used as an educational display example when discussing mineral identification, crystal structures, geological time and the way lighting affects the appearance of translucent or partly translucent material. Its distinctive name and backlit presentation make it a thoughtful gift for mineral enthusiasts, geology students, crystal collectors and anyone who enjoys natural history objects.
