How to Use Ideal-Scope & ASET Scope
Using the Ideal Light
Sit the diamond in one of the two holes. Place the calibration CZ in the other hole. Centre the Ideal-Scope or ASET over one of the stones. Only look at one stone at a time. Slide the scope across to view the other stone.
Refer to the IS Reference Chart and ASET Reference Chart for grading results.


Using a Desk Lamp
Tape a piece of copy paper to the front of a lamp Pick up the diamond with tweezers. Bring the Ideal-Scope or ASET up until the tweezers just touch the pink edge Hold the Ideal-Scope or ASET very close to your eye (like a pair of glasses). The best lighting is about 3-5cm (1-2 inches) from the paper
Note:
- Do not hold the stone inside the edge of the Ideal-Scope or ASET
- Tweezers are harder to use, but experienced graders find them faster
- Do not cover the pink plastic, hold black lens only with finger tips
- Direct bright lighting can make a individual facets shine (see example below)

unfiltered or uneven light can cause facets to shine (top right of star)
