A jewelers loupe (pronounced loop) is a smaller magnifying glass that folds into a metal protective case. It is used to view small jewelry pieces and gems to detect flaws and to read marks that can't be seen using normal vision. There are numerous characteristics to contemplate when buying a jewelers loupe based on individual demands.
The strength of the lens is described by a number followed by the letter "x" which stands for "times". For example 10x, 20x, 30x. The diameter of the lens is shown in millimeters, 12mm, 18mm, 21mm, etc. And the lens itself consists of either one, two, or three or additional lenses built into the assembly. The alot more lenses in the construction, the greater the quality. A lens will frequently be referred to as a doublet, triplet, and so on.
Some of the points to look for in a good quality lens are optical top quality glass, a roll pin in the hinge, and a leather case. Usually lower top quality loupes will be made from window glass with screws in the hinge, and have a plastic case. This is not usually accurate, but in most circumstances if you look for a name brand item and pay attention to the capabilities I've covered above the loupe you acquire will be a excellent one.
The appropriate way to use a jewelers loupe is straightforward and quick. Commence with a properly lit space or natural sunlight and a place to sit down so your hands will be steady. Make sure to clean the piece of jewelry and the lens with a soft cloth to remove surface dirt ahead of viewing. Also put a cloth underneath the function region to preserve items from rolling away if you drop them.
Expand the loupe and put your index finger through the metal case. Position the lens so that your thumb is above the case towards your face, and rest your thumb on your cheek so that the loupe is about an inch away from your eye. Normally if you are perfect handed you will hold the device in that hand, and vice versa.
You can preserve both eyes open or close one eye as long as it does not trigger eye strain. Hold the jewelry item with a pair of tweezers in your spare hand, and move it closer or farther away from your eye to bring it into focus. Preserve the loupe stationary. A gemstone will need to be viewed on all facets of the stone to examine every angle. Appear for dark inclusions inside the stone and any flaws in the cut of the facets.
If you are casual collector or a dealer in vintage jewelry it is superb to come to be familiar with utilizing a jewelers loupe properly. It takes a little practice but once you turn out to be proficient you will be able to identify beneficial gemstones, maker's hallmarks, and collectible jewelry.
