Loupe Clean
Loupe Clean is a quality standard in diamond grading that means a diamond appears completely clean when viewed through a 10x magnifying glass (called a loupe). This is an important skill for diamond professionals, as they need to carefully examine diamonds for any internal flaws or surface blemishes using this tool. When someone mentions "Loupe Clean" on their resume, it indicates they have expertise in detailed diamond inspection and can identify diamonds of exceptional clarity. This term is similar to saying "eye clean" but represents a higher standard of clarity since it involves magnification.
