What is a Gemologist? How to Utilize Expertise to Select your Perfect Diamond

Choosing a diamond is tough. Browse online and you’ll likely be presented thousands of options that vary in price (sometimes thousands of dollars) for “like” quality and size. Better yet, walk into a brick-and-mortar jewelry store and it’s the opposite, arguably too narrow in scope to know whether or not one quality is worth spending money on or how it benchmarks against your goals and budget. The nature of the jewelry business lends itself to “show the best” and “sell what we have today.” Does this remind you of other shopping experiences?


People take a lot of pride in their purchases, especially expensive, luxury, infrequent purchases like purchasing a diamond engagement ring or other fine jewelry. This is why many have “their jeweler,” someone you can trust based on years, sometimes decades of interactions and purchases from which you draw positive memories.


For many, it may be the first time you’re considering purchasing fine jewelry. Selecting the right diamond, whether or not it’s mined or lab-grown is just one component of shopping for an engagement ring. For most going through this process, it’s a once-in-a-lifetime decision that’s symbolic of your love and your commitment together. At times, the process may feel overwhelming, but in reality, it should be an exciting decision making process. A Gemologist will be able to communicate the value added attributes of diamonds and explain what makes it so unique to represent life's biggest moments.


As you research diamonds, you’ll come across dozens of local jewelers, thousands of online jewelers, and a world of articles and “how-to” perspectives like the one you’re reading. All the articles will pertain information in regard to a diamond's 4Cs. We’ve posted on the 4Cs of diamonds previously and have even dived deep into each component and their implications on the overall 4Cs of diamond.


Keep in mind, not all “Jewelers” are actually Gemologists. A GIA trained Graduate Gemologist Program is over 7 months of full-time commitment. Students are lead by world-class instructors, Gemologists, and jewelry industry experts. This means that students are put through a tried and true, rigorous training with a multifaceted discipline approach that’s both hands-on and textbook in nature.


According to GIA, “here are some of the topics covered in the Graduate Gemologist Program.”

  • Diamonds & Diamond Grading
    • Judge and grade diamonds by the 4Cs and color
  • Colored Stones & Colored Stone Grading
    • Learn the characteristics of colored stones, with a focus on ruby, sapphire, and emerald
  • Gem Identification
    • Identify more than 60 species of gemstones, distinguish natural gems from synthetics, and detect gem treatments
  • Equipment & Instrumentation
    • Learn diamond identification and grading skills GIA graders use
  • Treatments, Synthetics & Imitations
    • Identify diamonds that have been treated or are imitations
  • Market & Supply Chains
    • Understand how market factors and the supply chain affect value

As you can now see, it’s important to discuss your diamond options with a knowledgeable jewelry professional. The benchmark for diamond expertise is derived from a Gemologist. There is no one more well-versed in diamonds and gemstones than a Graduate Gemologist whose accreditation came from the Gemological Institute of America (GIA). A Gemologist has been trained specifically on diamonds and colored gemstones. The approximate stone count of an accredited Gemologist is into the thousands, thus you’ll find that Gemologists are both willing and able to dive deep into the importance of any and all technical aspects pertaining to the 4Cs of diamonds. Let’s be honest, who better to learn from than a person who took their passion, dedication, and skill set to become a Graduate Gemologist? Not only is this education coming from hands-on experience, but also from decades of educational materials from the creators of the 4Cs of diamonds, the Gemological Institute of America (GIA). You’ll quickly be able to understand how the scale works and how the different combinations of 4Cs lend themselves to rarity and therefore price implications.
