Description
Product Overview
This Grade A Opalised Marcasite specimen is a distinctive geological collecting piece from Indonesia, identified with the additional designation Miocene. Its appearance is especially suited to close examination and backlit display, where the photograph highlights its visible colours and translucence. The opalised marcasite identification gives this specimen interest for mineral collectors, geology enthusiasts, educational displays and natural-history décor.
The specimen is presented as a genuine crystal specimen with a naturally occurring mineral appearance rather than a manufactured decorative replica. Opalised marcasite is valued by collectors for the visual relationship between marcasite and opalised material, creating an unusual combination of mineralogical character, surface detail and light transmission. Backlighting can help reveal subtle changes in tone and areas of translucence that may be less apparent under ordinary front lighting.
Locality and Geological Identification
The recorded locality is Mount Cidolog, Pasanggrahan, Sagaranten, Sukabumi Regency, West Java, Indonesia. The specimen is identified as Miocene, providing a geological context for collectors interested in mineral specimens associated with Indonesia and its varied geological environments. Its locality information makes it a suitable addition to a labelled display, geology cabinet or regional mineral collection.
Display and Collecting
This Indonesian opalised marcasite specimen can be displayed as a standalone natural-history object, incorporated into a mineral cabinet or used as a conversation piece in a study, office, classroom or collection room. Its backlit visual character makes it particularly suitable for collectors who enjoy examining translucence and colour variation under different lighting conditions. It may also be chosen as a thoughtful gift for a mineral collector, geology student, rock enthusiast or anyone interested in unusual natural specimens.
The specimen’s natural visual qualities are best appreciated through close viewing. Compare the appearance in ordinary lighting with the backlit photograph to observe how illumination interacts with the translucent areas and visible colour. The supplied photographs are intended to show the actual piece and support an informed purchase decision.
