Advice for Determining Gemstone Value
Step 4: Gem Grading
Many new gemologists buy low-quality gems believing they’ve found a real bargain. However, judging gemstone value is very complex. You need to consider many factors before making a decision to buy. I’ve designed four exercises to help novices practice determining gem values.
Of course, these exercises have limits. You can’t always accurately judge gem colors through pictures on a computer monitor. Thus, when possible, I’ll give you image comparisons to work with. Also, values vary over time, so I’ll give you prices to use for each exercise.
