Diamond, Gemstone & Jewelry Dictionary

This is a diamond, gemstone and jewelry dictionary. It contains words commonly used in the jewelry industry.  It is my goal to define the words in this dictionary in a non-technical manner whenever possible.  

I want to talk with you not at you. I want this to be a pleasant experience for you and give you a better understanding of the terminology of my world. If there are words that you heard used in the jewelry business and they are not defined here, please let me know. Just fill out the Contact form below. I will gladly include them as I will be constantly adding additional words and definitions. You will find the A-Z pages that follow below. Just click the letter to go to the appropriate page to find your definition. My objective for my website is not just to sell jewelry and services but to become a resource for you. Thank you for taking the time to explore my website. I hope you will check back often.


All the best,
