Diamond Scribe Pen

The Diamond Scribe Pen is a dual-purpose tool designed for jewelers, gemologists, and metalworkers who need a reliable scriber and a quick preliminary stone-screening tool in one compact instrument. Styled and sized like a writing pen at 5-3/4" long, it features a retractable diamond tip that extends and retracts with a simple twist of the barrel — keeping the tip safely protected during storage and transport.

Features

• Retractable Diamond Tip: Twist-action barrel extends or retracts the tip for safe, convenient storage.
• Metal Marking: Functions as a traditional scriber for marking metals with precision.
• Preliminary Stone Screening: Provides a quick scratch test to help identify stones that are not diamonds — if a stone scratches under the tip, it is not a diamond.
• Pen-Style Form Factor: Familiar, comfortable grip that handles like a writing instrument.

Specifications

How to Use

1. Extend the tip by rotating the pen body until the diamond tip is fully exposed.
2. For metal marking, lightly scribe your line as you would with any standard scriber.
3. For a preliminary stone check, gently draw a short line on an inconspicuous area of the stone's surface.

Interpreting Results

• If the stone shows a visible scratch: it is not a diamond.
• If the stone does not scratch: further testing is required to confirm the stone's identity.

Notes

• Destructive test: This method may scratch the stone. Only perform this test if surface damage to the stone is acceptable.
• This tool does not differentiate between natural and lab-grown diamonds.
• This tool does not differentiate between diamonds and moissanite.
• Its sole screening function is to indicate that a stone which scratches under the tip is not a diamond — a non-scratch result does not confirm diamond identity.
