Handmade ring with black moonstone cabochon, created using copper electroforming. The blue adularescence of the feldspar emerges against a dark gray background with a more dramatic contrast than the classic white variety. A unique collector's item.

This specific piece
In black moonstone, the blue flash does not compete with the clarity of a white background: it emerges from a dark background that intensifies it, making it more focal and difficult to ignore. The effect is especially pronounced under natural side light.
The ring was constructed by electroforming: pure copper atoms are deposited onto the stone layer by layer, submerged in a special solution with constant electric current. The process can last between 8 and 24 hours, depending on the required thickness. The result is a setting that exactly follows the natural contour of the stone. The inside of the band is sealed so it does not leave a mark on the finger.
Moonstone in lapidary tradition
Named Adularia after its abundance in Mount Adular (Swiss Alps), moonstone was considered sacred in ancient Rome and India, associated with lunar cycles and intuition. The black variety, less widely distributed, adds connotations of introspection and is especially valued in contemporary gemology for the rarity of its dark base combined with intense blue adularescence. In crystal tradition, black moonstone is associated with introspection and connection with deeper lunar cycles.

Frequently asked questions
What is the difference between black and white moonstone?
Same mineralogy (potassium feldspar) but the black variety has a dark base matrix. The optical effect (adularescence) is identical in nature but the visual contrast is greater against a dark background.
What is electroforming?
It is a handcrafted process in which pure copper atoms are deposited onto the stone by continuous electric current while it remains submerged in a special solution. Unlike traditional setting, the metal does not bend or press against the stone: it grows onto it. Each piece requires between 8 and 24 hours of continuous process, plus prior preparation.
What is the hardness of moonstone and what precautions does it imply?
Mohs 6-6.5. Suitable for daily wear with care. Feldspar has cleavage which can produce microfractures from direct impacts. Remove before heavy tasks or crafts.
Is the stone dyed or treated?
No detectable treatment. The dark color and optical effect are natural properties of the mineral. The piece does not include formal gemological certification; statement based on lapidary observation.
How do I care for this ring?
The inside of the band is sealed, so it does not stain the finger with normal use. Clean with a soft dry or slightly damp cloth. Do not submerge or clean with ultrasonics. Store separately to avoid scratching other jewelry. Complete guide at jewelry care.
