Description
The professional standard for diamond grading and gemstone inspection, this 10X triplet loupe delivers high-clarity magnification at an exceptional value. Triplet loupes are the industry benchmark — constructed with three lenses bonded together to produce edge-to-edge sharpness that single and doublet loupes simply cannot match.
This loupe is corrected for both spherical aberration (minimizing distortion at the edges) and chromatic aberration (eliminating color fringing that uncorrected loupes exhibit). The result is a clean, accurate, true-color view that professionals depend on for diamond clarity and color grading. Under GIA standards, if a flaw is not visible at 10X magnification, it does not affect the clarity grade — making a reliable, corrected 10X loupe an essential bench tool.
The 18 mm diameter lens provides a wide field of view, while the non-slip rubber grip ensures secure, comfortable handling during extended inspection sessions. Each loupe ships with a leather case for protection and storage.
