The Precision Measuring Loupe from Kassoy ($83.95) is a specialty measuring loupe. Like a standard loupe, it features a 10x triplet lens, but it is designed to be either held in your hand or stand on a table, allowing the user the ability to look down into the well area. The quality of the precision loupe is apparent right out of the box. The loupe has a solid feel and the focus adjustment is very smooth. The lens on the bottom is durable and readable (through the loupe). It is important to note that the user will need an adequately lit area or an outside lightsource angled into the side of the loupe’s well. This is necessary in order to be able to read the scales on the lens base.
The lens base is imprinted with four scales for measuring: rings with diameters in millimeters, a grid that measures in 0.01 inch increments, a ruler that measures in millimeter increments, and angles by 1° increments. The large opening allows items to be placed into the well and on top of the lens. The lens with the measurement gauges is not removable. The loupe measures just over 2 inches tall, and just under 2 inches in diameter.
During my time using the Precision Measuring Loupe I came to the conclusion that it is a specialty tool that works best with loose stones. However the measurement plate is removable, this makes the loupe more versatile. Jewelry may also be placed in the well, but the scales are not as useful in this position. I found that if I put the jewelry under the measuring scale plate and looked down through it then the measuring scales were more usable. The quality of the loupe was impressive and I found the added benefit of the measurement scales to be useful. While I may not use the loupe on a daily basis, it is not an overly expensive item and I believe that it would easily find a place in my tool kit.
