Here are sample photos and descriptions of what the typical grades look like. The images tend to look darker than they actually are. AA, A+ and A grade diamonds are clear while B grade diamonds are cloudy and highly included.
Double A grade Herks are the cleanest grade available. These Herks show no flaws, contacts, stains or other problems to the naked eye. They are glass clear. Double A Herks are priced at 2 dollars per gram.
A+ Herks are slightly better than the A grade, but not of sufficient quality to be graded AA. They will only have the most minor of flaws, contacts or inclusions. A+ Herks are priced at a dollar and a half per gram.
A grade Herks will have limited visible inclusions, minor contact spots, and or, minor fractures which take up less than 10% of the crystal. They will have both terminations in tact and good overall form. A grade Herks are priced at 1 dollar per gram.
B grade diamonds are the "left overs". They are more highly included, incomplete or just down right poor. Don't expect any great specimens at this level. There are often chips and other mineral fragments in these low grade lots. B grade Herks are priced at 50 cents per gram.
