A five-mukhi bead is worth little. A fourteen-mukhi bead of the same size is worth a great deal. The difference between them, on the surface, is nine grooves — and a groove can be cut with a fine tool in a few minutes. Carving extra faces onto common beads is therefore the oldest and most widespread form of Rudraksha fraud, and detecting it is the bread and butter of Rudraksha testing.
How carving is done
The carver starts with a genuine bead, typically five or six mukhi, of the size and general appearance wanted. Using a fine engraving burr or hand tool, new grooves are cut between the existing ones, following the curve from pole to pole. Skilled work matches the depth and width of the natural grooves, textures the floor of the new cut to imitate the natural surface, and stains or oils the bead afterwards so that the fresh-cut wood darkens to match. Some carvers also sharpen or deepen the natural grooves so that all the lines look alike.
The result, to the naked eye, can be excellent.
What magnification shows
Under a stereo microscope at 10× to 40× the carved groove loses its disguise.
Floor texture. A natural groove floor carries the same fine granular pattern as the rest of the bead's surface, because it grew that way. A carved floor is tool-finished: smoother, sometimes with parallel tool marks, sometimes artificially roughened in a way that does not match the surrounding texture.
Edge quality. Natural grooves have rounded, slightly irregular edges that merge into the ridges beside them. Carved grooves have crisper edges where the tool cut through the surface layer, and the cut often exposes lighter wood beneath the darker skin.
Path. Natural grooves wander slightly with the bead's growth. Carved grooves are steadier and often do not quite reach both poles, fading out or ending abruptly near the crown.
Intersection with surface features. A natural groove runs between the bead's surface ornamentation. A carved groove cuts through it, slicing bumps and ridges in half.
Colour. Fresh cuts are pale. Staining and oiling darken them, but the match is rarely perfect, and stain collects in the tool marks.
The examiner records the natural faces and the artificial faces as two separate numbers.
What the X-ray shows
Whatever has been done to the surface, the interior of the bead is unchanged. A five-mukhi bead carved to show fourteen grooves still contains five chambers. The radiograph shows five, and the report records five compartments against fourteen surface lines — nine of them artificial. There is no way to carve chambers into a bead, and this is why radiography is the definitive test. How X-ray testing of Rudraksha works explains the image.
Partial carving and "improved" beads
Not every carved bead is a wholesale fake. A common intermediate case is a genuine high-mukhi bead with one or two grooves that were faint, damaged or incomplete, which a dealer has "improved" by deepening or extending them. The bead's true count may be correct. The report should still describe the work, because a bead that has been recut is a different article from one that has not, and because the buyer is entitled to know.
What a carved bead is worth
A carved bead is genuine seed, and if the buyer wants a five-mukhi bead, it still is one. The fraud lies in the count and the price. A report that states five natural faces, nine artificial faces gives the buyer both the truth about the bead and the evidence needed to recover the difference.
Frequently asked questions
Can carving be detected without an X-ray?
Skilled examination under magnification catches most of it. Very good work on a stained and oiled bead can be hard to call from the surface alone; the X-ray removes the doubt.
Do carved beads pass home tests?
All of them. Water, copper coin, warmth — the bead is genuine seed and behaves like one. Only the count is false.
Is a bead with "improved" grooves a fake?
Its count may be genuine, but it has been altered and should be reported as such. Whether that matters is for the buyer to decide with the facts in hand.
Which mukhi counts are carved most often?
Anything above eight, and especially the counts that command the highest prices: eleven, twelve, fourteen, and upward. One mukhi is a separate case, usually involving joined or substitute beads rather than carving alone.
Can a carved bead be restored?
No. Material has been removed. It remains a genuine bead of its original count with cosmetic damage.
