Detail
Size: small enough to be held like a (very large) loupe, includes a slot for a neck strap.
Field of view: ideally, object must be flat, focus range isn't large enough to see a hallmark inside a ring shank (see the picture of the diamond ring, the claws are in sharp focus, the ring shank is then too far away to be in focus).
Saving images: card slot for micro-card (card not supplied). For instance, see the picture of the ring, this could be used to show a customer which claws need replacing.
Laser-inscription reader: powerful enough to read the laser-inscriptions on diamonds. The photo was taken by pointing the camera at the lens, the inscription has not (as you will see on most web sites) been added onto the photo with Photoshop.
Magnification: Switchable to 3 magnifications: 9X, 12X, 19X. This is according to the manufacturer. Simply looking at the photos of the stamp, I'd say that the magnifications are far higher than this.
