Learning how to use a jeweler loupe properly is one of the most important skill that you have to acquire, whether you want to be a gemologist, a jeweler, a gemstones collector or a gemstone enthusiast.
Just a few pointers and you can handle a loupe like a professional diamond dealer.
A 10X loupe (magnification 10 times) is the standard used by jewelers. Take note that under the Federal Trade Commission of the United States, grading of diamonds must be done under a 10X loupe. Any flaws, blemishes or pin-point inclusions that are not visible under a 10X loupe is considered non-existent.
Hence, if you read a GIA Diamond Grading Report the Clarity Grades assigned to the diamond is viewed under a 10X loupe.
You should invest a small sum of money in buying a good quality loupe as it goes a long way for you.
You should look for the following:
- A triplet loupe which consists of 3 lenses composited together in such a way that edge and color distortion are eliminated.
- Loupe should preferably be housed in black casing, not in chrome or gold, either which will affect the color of the stone you are viewing.
How to handle a Loupe?
- Hold the loupe between the thumb and forefingers.
- Hold the stone with a tweezers.
- Your thumb should rest against your cheek about 1 inches from the eye.
- Slowly move the tweezers in front of the loupe until the stone is in focus. Your loupe should remain stationary.
- As you progress, try to keep the other eye open (what we call the ‘dead eye’). In this manner when you view a number of stones your eyes will not grow tired.
It’s just that simple. But remember practice makes perfect.
