Hand-Polished Orpiment – The "Alchemists' Gold" for Your Collection

There are minerals that exert an almost hypnotic effect solely through their color. Orpiment is one such stone. With its vibrant tones ranging from lemon yellow and honey gold to deep orange, it appears like petrified sunlight. However, this mineral is a true rarity in a polished state: with a Mohs hardness of only 1.5 to 2, it is extremely soft and possesses perfect cleavage.

A Masterpiece of Lapidary Art

Placing orpiment into a tumbling machine would result in its destruction. That is why you will find no mass-produced tumbled stones here, but exclusively hand-shaped unique pieces. Our lapidaries treat this delicate material with the utmost caution, following the natural cleavage of the crystal and polishing it until its characteristic pearly to resinous luster emerges. Each stone is a fragile work of nature, which we have photographed individually for you.

History: Of "King's Yellow" and the Search for Gold

The name itself tells the story: Orpiment is derived from the Latin aurum (gold) and pigmentum (pigment). In the Middle Ages, this deceptively real "gold color" misled many alchemists who believed they could extract actual gold from the mineral—an experiment that, of course, failed.

Its use in the arts was far more successful: known as "Royal Yellow" or "King's Yellow," orpiment was for centuries the most brilliant yellow available to humanity. Until the invention of chrome yellow in the 19th century, the robes of saints and kings in classical paintings often glowed thanks to this very mineral. The stone was also highly prized in ancient Egypt, where it was used extensively as a pigment.

Important Safety Notes & Handling

Chemistry: Orpiment is an arsenic sulfide (As2S3) and may contain traces of arsenic trioxide. Consequently, orpiment is classified as a highly toxic mineral; even historical sources issued stern warnings regarding its use. The official classification includes H301 (Toxic if swallowed), H331 (Toxic if inhaled), and H410 (Very toxic to aquatic life with long-lasting effects). Therefore, caution is essential!
Usage: This stone is a display piece for collectors; it is not a "worry stone" and is not suitable for carrying in your pocket. Under no circumstances should it be used for the preparation of gemstone water (direct immersion).
Precautions: Always wash your hands after direct contact with the stone. Do not eat or drink while handling the specimen. Ensure that the stone does not break and does not release any dust or particles.
Light Sensitivity: Orpiment can undergo physical changes over long periods when exposed to strong UV radiation. It is best to store your specimen away from bright, direct sunlight.
