Immersion cell
Capable of rapid & easy detection of treated gems
characteristics: such as clarity
enhancement, HPHT annealing,
irradiation, & surface coloration, the
immersion cell is especially useful for
rubies.
Large gem stags plate
Magnetically attachable &
covering the stage area of the
GM168 base to provide a large
surface far rough stones and large gems
(i. e. fade) inspection in conjunction with the
incident fluorescent illumination.
Gemological
The GEM-250 utilizes the optical performance of MRC’s GEM-250 stereo microscope to enhance distinct three-
dimensional details with a zoom function. Rugged and precise, the optics of the GEM-250 performs analyses and
measurements more accurately & efficiently thus reducing your workload. At a working distance of 113mm,
manipulation of the inspected gem or the addition of a further apparatus is permitted without obstruction Available
in a trinocular version for photographic or digital capture of the gem, the GEM-250 provides you with an opportunity
for extra revenue. Moreover, when teamed with MRC’s RCam 480, the GEM-250 becomes
GEM-250, Stereo Gemological Microscope
your instrument of instruction for teaching and
training by showcasing the gem in real time via a
television, a projector, and computer simultaneously.

Integrating a consistent & powerful SOW
Quartz Halogen Bright field illumination with
a precise, adjustable aperture diaphragm
[041mm - 02mm}, you are able to measure
with a table gauge the proportions and
pavilions of a diamond.
Dark Field Illumination
Dark field is the ideal illumination for
observation of inclusions. With MRC’s
versatile aperture diaphragm [pictured
above], you can control the depth of field
and contrast while using the dark field
illumination for better identification.
Incident fluorescent illumination,
Diamond Light
Designed for use with diamonds, the
incident light can be adjusted for a
thorough examination of the clarity, color, &
finishing. The bulb has a color temp. of 6000K
to reduce any yellowing effects on the gem.
