oravunel™ MeasureMark 6-Inch Digital Caliper for Mineral Specimen Measuring & Cataloging

A compact digital measuring tool for recording specimen dimensions consistently in inches or millimeters.

Made for a More Thoughtful Collection

MeasureMark is designed for collectors who want more precise size information than a standard ruler provides. It is useful for documenting the length, width, and thickness of suitable mineral specimens, polished stones, and small collection objects. The digital display makes readings easy to view, while the sliding jaws support repeatable positioning on compatible surfaces. Switch between inches and millimeters for American collection records or metric references. Natural minerals often have irregular surfaces and fragile crystal points, so measure gently at suitable contact areas rather than squeezing a specimen between the jaws.
