Carborundum Raw Stone
Carborundum is a lab-made silicon carbide crystal traditionally associated with cleansing, grounding, and transformation. This raw specimen is a synthetic (man-made) material, not a natural mineral, with a brilliant metallic rainbow luster of electric blues, purples, and greens — a real showstopper on a shelf. Each piece is unique in shape and the play of rainbow color.

Meaning & history
Carborundum is manufactured by fusing silicon and carbon at very high heat, which produces its signature glittering, rainbow-iridescent coating — it is not mined from the earth like a natural crystal. Despite being man-made, many people associate its bright, mirror-like surface with cleansing, grounding, and lifting the energy of a space. A striking addition to any protection and grounding collection, or see more for balance and wellness.
How to use it
Display this specimen where its rainbow shimmer can catch the light — a shelf, windowsill, or altar. Because of its sharp edges, it’s best kept as a display piece rather than carried in a pocket.
Care & cleansing
This is a lab-made (synthetic) crystal, and its metallic edges can be sharp — handle with care to avoid cuts, and keep it out of reach of young children. Wipe with a soft, dry cloth rather than soaking; avoid abrasive cleaning that could dull the rainbow coating.
Frequently asked questions
What is carborundum and what is it used for?
Carborundum is a lab-made (synthetic) silicon carbide crystal, not a natural mineral. It is traditionally associated with cleansing, grounding, and transformation. This is a decorative/symbolic piece, not a health product or medical device.
Is carborundum water-safe?
A quick wipe is fine, but avoid soaking. Its sharp metallic edges also mean it should be handled carefully when wet or dry.
Can I handle carborundum daily, and is it sun-safe?
It's sun-stable for display, but because the edges can be sharp, treat it as a display piece rather than something to carry or handle often.
How do I cleanse and charge carborundum?
A soft, dry wipe-down or brief time near moonlight works well. Avoid abrasive scrubbing, which can dull the rainbow coating.
Is carborundum a natural crystal?
No — carborundum (silicon carbide) is lab-made, produced by fusing silicon and carbon at high heat. Its dazzling rainbow iridescence is a feature of this manufacturing process, not natural mineral growth.
What pairs well with carborundum?
Carborundum is often paired with black tourmaline or hematite for grounding, or displayed alongside other iridescent pieces like aura quartz for a shimmering display.
