Abstract: A magnifying attachment for a flashlight body includes an eyepiece viewing portion which when rotated to a 90.degree. open position provides for dark field illumination of a gem specimen. The attachment includes a split resilient band which may be easily slipped over the end of the flashlight with the band including a folded back tab terminating in a hook which provides a half bearing into which the rotational axis of the eyepiece viewing portion may be permanently placed and retained on the flashlight. A depression or detent notch is formed on the flashlight body to retain the attachment.

Abstract: A portable unitary battery powered hand-held magnifying apparatus which is especially useful for examining gems includes a tubular battery casing with a penlight bulb mounted at its end to provide the necessary dark field illumination for showing inclusions in a gem. A ten power triplet type magnifying lens is hingedly mounted to the end of the tube for convenient carrying but when moved 90.degree. its lens' axis is then perpendicular to the nominal light axis. The light bulb is in a parabolic reflector to provide substantially parallel rays. The focal distance of the lens is at the light axis where a gem would be placed for examination.
