Original Press Release:

Aven Gemscope's Multiple Light Sources are an Advance for Jewelers, Gemologists

Powerful magnification and bright lighting from multiple sources distinguish the new Aven Gemscope.

This specialized binocular stereo microscope has a magnification range of 10x to 44x. Upper and lower illumination assures bright, distortion-free surface and interior inspection of diamonds, other gemstones, crystals and jewelry-grade minerals.

A dimmable halogen lamp is supplemented by a halogen pipe light, as well as an independently controlled 9-watt fluorescent front light. A movable gem tweezer with two positioning posts holds specimens firmly on the right or left side of the adjustable iris diaphragm.

"The stand-mounted Aven Gemscope is added to our line of industrial and scientific scopes to meet the needs of jewelers, gemologists and mineralogists," says Mike Shahpurwala, president of the global supplier of optical instruments and precision tools. "With superb optics and outstanding illumination, it's ideal for examining gemstone inclusions, as well as accurate grading or appraisals."

The zoom ratio is 4.4:1 and the field of view is 23 mm (0.9") to 5.3 mm (0.2"). The working distance of 90 mm (3.5") allows ample room for use of tools while stones are magnified.

Eyepiece tubes are inclined at 45 degrees and have rubber cups for comfort during extended use.


The Aven Gemscope, which includes a dust cover, is mounted on a study stand that can be inclined up to 10 degrees. The body can be accessorized with different eyepieces and auxiliary lenses for needed magnification and working distance.

The manufacturer is Carton Optical Co., Ltd., a leading professional optical supplier since 1951. "This reliable firm's instruments are thoroughly tested for quality and durability," says Shahpurwala.
