About this specific piece
The "rainbow" designation in moonstone refers to the adularescence spectrum not being limited to blue: it also includes golden, pale green, and violet flashes depending on the angle. It is the variety with the widest chromatic range within the species, the most sought after in feldspar gemology.
The oval cabochon evenly distributes the sampling area of the optical phenomenon. The copper setting surrounds the stone with a warm frame that contrasts with the cool, pearly tone of the mineral, without competing with its visual prominence.
Moonstone in lapidary tradition
Adularia has been an ornamental stone in Mediterranean and Asian cultures since ancient times. In Rome, it was known as Selenitis (after Selene, the lunar goddess). In India, it is a sacred stone associated with Chandra (the moon god) and used in ritual and wedding jewelry. The "rainbow" designation refers to the variety with multiple adularescence colors originating mainly from Karnataka and Tamil Nadu (India).
In crystal tradition, rainbow moonstone is associated with intuition and connection to natural rhythms.

Frequently asked questions
What is adularescence and why does it change color?
Adularescence is an optical phenomenon caused by the interference of light between alternating layers of two feldspars within the same structure. The perceived color changes with the viewing angle because the optical thickness of the illuminated layers varies.
What is the hardness of moonstone?
Mohs 6-6.5. Suitable for rings with moderate use. Feldspar has cleavage in two directions; direct impacts can cause fractures. Remove during physical or manual activities.
Can adularescence be lost?
No. It is an intrinsic property of the mineral's structure. However, a scratched surface reduces the quality of the optical effect by blurring the reflection.
Is the stone dyed?
No detectable treatment. The adularescence colors are completely natural. No formal gemological certification; statement based on lapidary observation.
How do I care for this ring?
Clean with a soft dry cloth. Do not submerge or expose to ultrasonic cleaners. Store in an individual case. Full guide in
