Our Diamond List 

To the unsuspecting individual, buying a diamond can be a lot like walking through the jungle: hidden traps everywhere; an air of intimidation; things that aren't what they appear to be; an entirely unknown language. Without a guide, it's easy to become lost in this environment, which can lead to a bad decision. We're so confident about the quality of all our diamonds; we actually encourage you to comparison shop. John Anthony Jewelers has also put together a diamond guide so that if you comparison shop for a diamond, you'll know exactly how to compare the diamonds you'll find listed here in our inventory with others.

GIA Grading

Most jewelers use the widely accepted "GIA" grading system developed by the Gemological Institute of America (GIA). Without an "expert" such as a Graduate Gemologist to interpret, this terminology is meaningless. A Graduate Gemologist diploma certifies that an individual has successfully completed a rigorous, uncompromising course in the study of gems. Would you go to a doctor without a medical degree? Then, why would you buy a diamond from a "guy who knows diamonds"?

Make sure you deal with a professional. John Anthony Jewelers guarantees that all our diamonds are accurately graded using strict GIA guidelines.
