Making a Polished Stone Pendant — Prehistoric Personal Ornament

Stone pendants are among the earliest personal ornaments in human history, with examples found at archaeological sites dating back over 100,000 years. A pendant is a flat stone that has been shaped, smoothed, polished, and perforated with a suspension hole so it can be worn on a cord around the neck. The oldest known examples include perforated marine shells and flat stone pendants from Blombos Cave in South Africa (circa 75,000 BCE) and the Grotte du Renne in France (circa 42,000 BCE, attributed to Neanderthals). Suitable materials include soapstone (steatite), slate, serpentine, jade, schist, and any attractive stone that is soft enough to shape and drill with stone-age tools. The drilling technique is the most challenging step — a flint drill point or bow drill with wet sand as an abrasive is used to bore a clean hole through the stone. The hole must be drilled from both sides to prevent breakout, where the drill punches through and chips the exit surface. This blueprint covers selecting a stone, shaping it by grinding, polishing the surface, drilling the suspension hole, and threading it on a cord.

1

Select a Flat, Attractive Stone

Choose a flat stone 4 to 7 cm long, 3 to 5 cm wide, and 5 to 8 mm thick. Soapstone is the easiest material — it is soft (Mohs 1 to 2), comes in attractive greens and greys, and polishes to a smooth satin finish. Slate, serpentine, and schist also work well. Avoid stones harder than Mohs 5 — they are extremely difficult to drill with stone tools.

Rough Out the Basic Shape

If the stone is not already close to the desired pendant shape, rough it out by tapping the edges with a small hammerstone to remove excess material. Strike at a low angle to chip away small pieces rather than risking a crack through the centre. For soapstone, you can also score a line with a flint point and snap along it. Aim for an oval, teardrop, or disc shape.

Grind the Pendant to Final Shape

Rub the rough pendant against a flat sandstone slab in long, steady strokes. Work all edges and both faces until the shape is symmetrical and even. Grind the edges to a smooth curve — no sharp corners that could catch on clothing or snap off. Check the thickness — the pendant should be at least 4 mm thick at the narrowest point to survive drilling.

Smooth Both Faces on Progressively Finer Stone

After shaping on coarse sandstone, switch to a finer-grained sandstone or siltstone slab. Rub both flat faces in circular motions until all visible scratches from the coarse grinding are removed. The surface should feel smooth to the touch with no rough patches. This step typically takes 15 to 20 minutes per face.

5

Polish the Surface to a Satin Finish

Wet the pendant and rub it vigorously with a piece of soft leather or a smooth water-worn pebble. The combination of water, pressure, and the fine natural abrasive in the stone itself produces a satin polish. For soapstone, this step transforms the surface from matte grey-green to a glossy, almost waxy sheen. Continue until the surface reflects light.
6

Mark the Drill Hole Position

Mark the position for the suspension hole near one end of the pendant, approximately 5 to 8 mm from the edge. The hole must be far enough from the edge that the remaining stone can support the weight of the pendant without cracking, but close enough that the cord hangs naturally. Scratch a small cross or dot on both sides of the pendant at the exact same position — alignment from both sides is critical.

Create a Starting Dimple on Each Side

Using a sharp flint point, press and twist firmly at the marked drill position to create a small conical dimple on each side of the pendant. These dimples guide the drill point and prevent it from wandering across the polished surface. The dimple should be about 1 to 2 mm deep — just enough to seat the drill point securely.

Prepare a Flint Drill Point

Select or knap a small flint flake with a strong, pointed tip. The drill point should be 2 to 3 mm wide at the tip and taper to a sharp point. If using a bow drill, haft the flint point into a short wooden dowel by splitting the end and binding the flint in place with sinew. For hand drilling, the point can be held directly between the fingers and rotated.

Drill from the First Side with Wet Sand

Place the pendant flat on a leather pad or soft wood surface. Add a pinch of fine wet sand to the dimple — this acts as an abrasive that does most of the actual cutting. Press the flint drill point into the dimple and rotate it between your palms (or use a bow drill for faster rotation). Apply steady downward pressure while rotating. Add fresh wet sand every 30 seconds. Drill halfway through the stone thickness, then stop.

Flip and Drill from the Second Side

Turn the pendant over. Place the drill point in the dimple on the second side and drill downward in the same manner with fresh wet sand. When the hole from the second side meets the hole from the first side, you will feel the drill suddenly push through with less resistance. Drilling from both sides prevents the exit breakout that occurs when drilling straight through from one side.

Smooth and Widen the Hole

Insert a thin pointed stone or a rolled piece of wet sandstone into the hole and rotate it to smooth the interior walls. The finished hole should be 3 to 4 mm in diameter — wide enough for sinew or thin cordage to pass through easily, but not so wide that it weakens the surrounding stone. Remove any sharp edges around both openings by gently grinding with fine sandstone.

Final Polish After Drilling

The area around the drill hole may have been scratched during drilling. Give the entire pendant a final polish with wet leather or a smooth pebble to restore the surface finish. Pay special attention to the edges of the drill hole — they should be smooth and slightly rounded.
13

Thread the Pendant on Cordage

Cut a length of sinew thread or plant-fibre cordage approximately 60 to 80 cm long — enough to pass over the head with room to spare. Thread the cord through the drilled hole and tie a secure knot. For sinew, wet it first to make it pliable, thread it through, and let it dry — it shrinks and tightens as it dries, forming a permanent knot. For plant cordage, use a simple overhand knot doubled back on itself.

Assess the Finished Pendant

Hold the pendant by the cord and let it hang freely. It should hang flat with the polished face forward. Check that the cord moves freely through the hole without catching. The pendant should feel smooth in the hand with no sharp edges. A well-made soapstone pendant weighs approximately 20 to 40 g — light enough for comfortable daily wear. The finished piece is both a personal ornament and a demonstration of core Stone Age skills: shaping, grinding, polishing, and drilling.
