VGM Table Jewelry Microscope Base Stand Gemological Microscope Equipment for Gem Identification
 |
Humanization Design Ellipse Base 10W Halogen Light 10W daylight top lamp |
The joint of the lamp is easy to adjust the illuminator angle, and the focusing movement is 125mm for observing the gem and jewelry with different sizes.
The steel gem clip has moderate firm and reduce the light blocking the waist of the gem, which make a all-round observation.
The mounting holes of the gem clips both sides of the table provide the adjustment of eye point and angle.
Reasonable illumination configuration will provides comfortable and easy operation. We also provide the accessory gem clips, steel wire clip and flat clamp for operators.
The crystal characteristics of the inner and outer structure of the gem will be better observed by the polarizer.
This microscope is widely used in jewelry appraisal institutions and colllege/ university.

Identified the surface characteristics of the sample: gem’s growth striation, etch fugure, scratch, damage, symmetry, split surface (bubble, gloss difference) etc.
Observe the intrinsic characteristics of the sample: inclusions’ type, shape and quantity, double crystal surface, growth striation, color distribution characteristics, initial cleavage, defect etc.
Observe the doubling of facet edge: the doubling of facet edge of the gems with high birefringence, such as zircon(DR=0.059), olivine (DR=0.036) and tourmaline (DR=0.078).
