Andesine Labradorite
Vivid copper-red feldspar with labradorescent green flashes - andesine-labradorite sparked decades of gemological controversy and remains one of the trade's most debated gems.
- The andesine controversy involved major gemological institutions including gemological laboratories, SSEF, and Gübelin all publishing competing interpretations of the same stone species.
- Natural red color in feldspar is caused by copper inclusions - the same element used in artificial copper-diffusion treatments, making distinction challenging even under laboratory conditions.
- Tibet's Changbaishan region was proposed as a source of naturally red andesine; some specimens from this locality were authenticated as untreated by multiple labs.
- Andesine labradorite displaying both strong red color and visible green labradorescence is particularly prized - the two optical effects together are visually spectacular.
- Despite the treatment controversy, andesine labradorite helped spark broader gemological research into diffusion treatments across multiple gem species.
- Collectors of unusual red-colored gemstones
- Feldspar enthusiasts who know the andesine controversy
- Bold, unconventional jewelry with distinctive character
- Fire and earth energy work in crystal practice
- Those drawn to stones with complex, debated histories
- Buyers expecting guaranteed untreated material (disclosure required)
- Everyday ring wear (choose ruby or spinel for durability)
- Collectors wanting clear gemological certification (controversy remains unresolved for some parcels)
What Is Andesine Labradorite?
Andesine Labradorite is a plagioclase feldspar with composition intermediate between andesine and labradorite on the feldspar series. It attracted enormous gemological attention from the early 2000s onward when vivid red specimens appeared on the market from Congo (DRC), Tibet. It rates 6 - 6.5 on the Mohs hardness scale.
Mongolia - a dramatic red feldspar with green labradorescent flash that gemologists had rarely encountered before.
The stone's origin story has been one of the most contentious debates in modern gemology. Numerous studies by gemological laboratories and other labs suggested that some - possibly most - of the red coloration in commercial 'Congo andesine' resulted from copper diffusion treatment, making the material artificially colored.
Some parcels tested as natural; others showed clear evidence of treatment.
Regardless of treatment debates, the optical beauty of andesine labradorite is undeniable. Faceted stones show vivid orange-red to red body color combined with occasional green labradorescence - a dramatic combination unlike any other commonly available gem.

Meaning and Symbolism
Andesine labradorite is traditionally associated with passion, vitality, and the courage to act boldly in pursuit of what matters most. Its vivid red color links it to fire energy - transformation, motivation, and the heat of creative or romantic engagement.
Practitioners believe andesine labradorite combines the root chakra's grounding life-force energy with the heart chakra's emotional warmth, creating a stone that is both physically energizing and emotionally connecting. It is said to dissolve fear-based inertia and replace it with passionate forward momentum.
The labradorescent flash is thought to add an element of surprise and revelation to the stone's energy - reminding the bearer that what appears fixed and solid always contains hidden dimensions of light and possibility.
Historical Timeline
Healing Tradition
Emotional
Andesine labradorite is traditionally associated with emotional courage and the willingness to pursue passion without restraint born from fear. Practitioners believe its fiery red energy dissolves apathy and emotional numbness, reconnecting the bearer with the vitality and desire that make life meaningful.
It is said to support those who have become overly cautious or have suppressed their emotional needs for the sake of stability. Crystal healers sometimes recommend it for people recovering from periods of emotional shutdown or disconnection from joy.
Spiritual
Spiritually, andesine labradorite is thought to bridge grounded physical vitality with the expansive spiritual awareness of labradorite. Practitioners believe its fire energy activates spiritual will - the capacity to act on spiritual insights rather than merely receiving them.
The green labradorescent flash is said to add a heart-opening quality, ensuring that fiery spiritual action remains guided by compassion. Some traditions use it as a stone for spiritual courage - the willingness to walk an authentic path even when it diverges from social convention.
Physical
Andesine labradorite is traditionally associated with physical vitality, circulation, and energetic warmth in crystal healing frameworks. Its red color links it to blood and life force energy in many folk traditions, where red stones were used to support physical strength and endurance.
Practitioners sometimes suggest it for people experiencing chronic fatigue or reduced physical motivation, describing it as an energetically stimulating stone. These associations are traditional and metaphysical; andesine labradorite is not a medical treatment.
Zodiac, Birthstone and Gifts
Sagittarius, drawn to bold experiences and passionate exploration, resonates with andesine labradorite's fiery energy and the element of surprise in its labradorescent flash. Aries, the fire sign most associated with courage and initiative, is thought to find its own nature amplified and focused by this stone's combination of red vitality and hidden depth.
Leo's creative passion and generous heart are said to align with andesine labradorite's dual root-and-heart energy, supporting authentic self-expression from a place of both strength and warmth.
Care and Cleansing
Sound cleansing with a singing bowl or drumming is the recommended method - it poses no risk to the stone's surface or feldspar cleavage, and is considered energetically effective. Brief moonlight exposure is appropriate; full moon light is particularly resonant given the labradorite component's traditionally lunar associations.
A quick rinse under cool running water is acceptable; dry immediately and avoid salt water or prolonged soaking that can damage the feldspar's polished surface.
- DO store away from harder stones including diamonds, sapphires, and topaz that can scratch its 6 to 6.5 Mohs surface.
- DO NOT use ultrasonic or steam cleaners - feldspar cleavage is vulnerable to vibration and heat.
- DO NOT expose to salt water, harsh chemicals, or strong acidic cleaners.
- NOTE that if purchasing treated material, some treatments may not be fully stable under prolonged UV or heat exposure - ask your dealer about treatment stability.
- DO NOT set in high-exposure ring settings; pendant, earring, or bezel settings offer better protection for the stone's relatively soft surface.
Real vs Fake
The central authenticity question with andesine labradorite is not whether it is genuine feldspar, but whether its red color is natural or the result of copper diffusion treatment - a distinction requiring gemological laboratory testing.
Copper diffusion-treated stones often show color concentrations near the surface or along cleavage planes that are visible under magnification - a telltale sign of treatment penetrating from outside.
Natural red andesine shows homogeneous color distribution throughout the stone when viewed under magnification; treated material may show uneven zoning related to treatment penetration depth. Under long-wave UV fluorescence, treated material may show different reactions than natural material - laboratory testing using fluorescence, EDXRF, and spectroscopy is definitive.
Always request a laboratory report from gemological laboratories, AGL, or another respected lab for any significant andesine labradorite purchase; disclosure of treatment status is both ethically required and practically important for value assessment.
Andesine Labradorite Jewelry & Gifts
Andesine labradorite prices vary significantly based on treatment status: lab-certified natural specimens command $80 to $150 per carat, while disclosed treated material is available at $20 to $60 per carat.
Always request disclosure of treatment status and ideally a lab report from a reputable gemological laboratory before purchasing any significant andesine labradorite piece.
The finest specimens show vivid orange-red to deep red body color combined with visible green labradorescent flash - this combination is the most desirable and commands premium pricing.
Congo, Tibet, and Mongolia are the claimed sources for natural material; Tibetan and Mongolian origin specimens have been more consistently authenticated as natural by laboratory testing.
For jewelry use, choose protected settings like bezels or channels given the stone's moderate hardness and feldspar cleavage - beautiful pieces are absolutely achievable with appropriate design choices.
