My Top 10 Diamond Websites
I found these sites to have excellent sections on diamond education.
I highly recommended JamesAllen.com’s diamond education as they address most concerns one would be faced when buying online. Do check out their live chat too as that can save you heaps of time searching for some information on diamonds.
You may also want to take a look Diamond International’s Learning Pages. They touch on a few more subjects such as how to buy the right type of jewelry and they explain what different words mean when referring to ring styles. Definitely worth a look.
