Q:
What is a Loupe and how do I use it?
A:
A loupe is a specialized magnifying glass used for inspecting gems and jewelry. Good ones have 3 lenses in them and magnify at least 10x. To use a loupe, hold it about 1 inch from your eye resting the hand holding the loupe on your cheek. Hold the diamond about 1 inch in front that with your other hand and rest that hand on the first hand holding the loupe. To focus, move the diamond closer or further from the loupe. Keep both eyes open to reduce eyestrain. Once you are comfortable using the loupe, here's what to look for. Read our Diamond Anatomy page for more details.
