If you are in the market to purchase a piece of diamond jewelry or loose diamond, you will certainly come face to face with some jewelry jargon that you may or may not quite understand. Today, I wanted to share some common jewelry terms that you should know as you continue your search for either a loose diamond or for a piece of jewelry. As a deBebians GIA graduate gemologist, I am happy to assist you further if you need clarification on any of the following jewelry terms or any other term that you may not be familiar with. 
- Eye clean: This means that although the diamond has inclusions, you will not be able to see them with your naked eye. You will need a 10x loupe or microscope in order to see the inclusions.
- Out of round: This is referring to a round diamond or gemstone that no longer has a perfect circular perimeter. Perhaps there is a chip in the diamond/gemstone and therefore what was once a perfect circle, is no longer.
- Loupe clean: This means that even with a loupe, it’s almost impossible to see any inclusions in a diamond. This would most likely be for a VVS diamond or higher clarity.
- Face up: This refers to the positioning of the diamond. It refers to looking at a diamond from the top down. Imagine the diamond standing up like an ice cream cone with the point down. You would be looking through the scoop of ice cream!
- Canary: This refers to all yellow diamonds past Z color (fancy color). This includes fancy light yellow through fancy deep. Canary is basically just referring to yellow, but not the intensity of the yellow color.
- Spread: This refers to the overall length and width of a diamond or gemstone. You must remember that carat weight is just the weight so be sure to look at the overall measurements to find a stone that measures well. Spread is often used with the term ‘face up’ as you judge the spread (overall size) of the diamond or gemstone.
As a gemologist, I tend to use these terms quite often. I find that some customers are familiar with these terms while others are not. This is a short, handy list for your reference.
