Grade A Opalised Marcasite Crystal Specimen Indonesia Miocene Geology Collection Backlit Colours & Translucence

Description

Specimen Description

This Grade A Opalised Marcasite is presented as a distinctive crystal specimen from Indonesia, with the additional identification Miocene. Its appearance is especially suited to collectors who appreciate unusual mineral textures, changing colour effects and natural translucence. The opalised description and marcasite identification combine to create a specimen with strong visual interest for a mineral collection, geology display or decorative cabinet.

The backlit presentation is an important feature of this listing. Light passing through or behind the specimen highlights colours and translucence that may be less apparent under ordinary front lighting. This makes the piece particularly appealing for collectors who enjoy examining minerals under different illumination, photographing natural specimens or creating a display with varied visual effects. The photograph shows the actual specimen you will receive.

Locality and Geological Context

The recorded locality is Mount Cidolog, Pasanggrahan, Sagaranten, Sukabumi Regency, West Java, Indonesia. This precise locality information adds useful geological and collecting context to the specimen. Indonesia is well known among mineral collectors for its varied geological environments and visually distinctive natural specimens, while West Java is an established region of interest for geological collecting.

Miocene is a recognised geological epoch used to describe a period in Earth history. As supplied, this term forms part of the specimen’s additional identification and provides a geological time reference for collectors and students. The locality and Miocene designation make this specimen suitable for educational collections focused on mineral identification, regional geology and geological time.

Collecting and Display

Opalised marcasite specimens can make an unusual addition to a collection because they offer a different look from more familiar, uniformly coloured mineral pieces. The combination of the named material, natural surface character and translucent visual response gives this specimen decorative appeal without taking away from its geological interest. It can be displayed alongside other Indonesian minerals, Miocene-associated geological material or specimens selected for unusual optical appearance.

This piece is suitable for a mineral cabinet, geology classroom display, natural history shelf, photography project or thoughtful gift for a collector. Backlighting can be used to explore the specimen’s colour response and translucence, while ordinary display lighting allows its overall form and surface character to be viewed naturally. Handle and display the specimen thoughtfully as appropriate for a natural collectible.

Authenticity and Sizing

The specimen’s Indonesia locality, Mount Cidolog area reference, Miocene identification, opalised marcasite description and backlit colour and translucence highlights are all part of its collecting appeal. It is a suitable choice for mineral enthusiasts seeking a distinctive geological specimen with a documented locality and an especially attractive photographic presentation.
