For gemologists, the 10X loupe (with ten-power magnification) is the standard for hand-held gem identification. Although you’ll find more powerful loupes, the depth of field (the area that’s in focus) is so small above 10X that they’re hard to use. Instead, use a microscope when you need higher magnification..
How do I choose a loupe?
Magnification – The higher the magnification the smaller the field of view will be. Magnification is the last choice that you have in the dental loupe selection process. You need to determine on your own what magnification you feel most comfortable with and allows you to work effectively.
How can you tell a diamond from a loupe?
Heat the stone over a lighter for 30 seconds and immediately drop it into a glass of water. A real diamond will be unaffected by dramatic changes in temperature and it will simply fall to the bottom of the glass. Fake diamonds however will shatter immediately.
Should I buy a loupe?
Whether you’re a jeweler, rock collector, or a coin and stamp enthusiast, owning a quality jeweler’s loupe is essential to the enjoyment of your craft or hobby. In fact, many loupe advocates own multiple magnifiers so that they’re never without one when they need it.

How strong is 10X magnification?
Field of View:
At 10 power (10X), it is about 0.5″. Usually, it is best to use low power for scanning larger surfaces and high power for small areas.
What is the rarest color in diamonds? Red diamonds are the rarest and some of the most expensive in the world. Also known as Fancy Reds, they come in a variety of shades ranging from orange-red to brownish red. Majority of the world’s red diamonds come from the Argyle Diamond Mine in Australia.

Do fake diamonds sink in water?
True diamonds have high density and should quickly sink to the bottom of the glass. Fake diamonds are not as thick, and therefore, more likely to float in water. This test is not always foolproof. Some materials that make up fake diamonds, such as cubic zirconia and moissanite, can sink if they are heavy enough.
Can the average person tell the difference between cubic zirconia and diamond?
You can easily tell the difference between the two if your measurements are correct and if you are using a standard scale. Another differentiating feature is that diamonds are the hardest substances found in the world. Their hardness is around 10 on the Mohs scale.
Why are my diamonds blue under UV light? Some diamonds fluoresce when they are exposed to ultraviolet (UV) rays from sources like the sun and fluorescent lamps. This can cause them to emit a bluish light or more rarely, a yellow or orangy light. Once the UV light source is removed, the diamond stops fluorescing. 2.

Can I use a loupe with glasses?
Implementation of Prescription of Eyeglasses with Loupes: FLM loupes are mounted in front of eyeglasses (bifocal areas of eyeglasses) and thus optics of FLM loupes do not require prescription lenses. But TTL loupes require prescription lenses as a part of the eye lenses of TTL loupe optics.
What magnification do surgeons use?
As a general rule, the magnification of 2.5 to 3.5 is appropriate for most microsurgical procedures – however, for intricate procedures, especially those involving tendon and blood vessel repair, magnification levels of 4.5 and 5.5 can be more helpful and provide higher precision.
How do you attach loupes to glasses?
What are TTL loupes?
TTL loupes stand for “through the lens” loupes and are also known as ‘front mounted’ loupes. The optical barrels (oculars/magnifiers) are actually mounted into the lens of the loupes, based on the users individual pupillary distance and working distance measurements.
What magnification do you need to see diamond inscription?
What is the best magnification to view a diamond inscription? Based on the magnification of the viewer we sell (see below), the magnification is 20x. It will always take a little time to set up to view the inscription but provided the number is not too faint, it should be visible at this magnification.
How do you tell if a diamond is real with a flashlight?
Simply hold the loose diamond near a light source, like a lamp, and see the reflection of the light from the diamond. This test will be best if there is another gem that you’ll compare along with it, like cubic zirconia. You’ll see how different their effects are to light.
What magnification do you need to look at diamonds?
WHY IS 10X MAGNIFICATION of A Diamond THE INDUSTRY STANDARD? Ten times’ magnification under a microscope is the standard magnification in the diamond industry as a result of the creation of the Clarity Rating Scale. This scale is the standard used throughout the diamond industry.
