Summary

Shopping for a diamond? These essential tools help you compare size, quality, and value with confidence.

  • Diamond size chart: Visualize carat sizes across different shapes for better perspective.
  • 4Cs guide: Understand cut, color, clarity, and carat to assess quality.
  • Comparison tools: Use apps and charts to evaluate prices and certifications side by side.

 

Diamond shopping can feel overwhelming. There’s so much to know about the details of a diamond – how to spot an imperfection, how a diamond’s shape affects its shine factor, whether carat or color is more important for maximum sparkle ... the list goes on.

Avoid anxiety and confusion by using these jewelry cheat sheets as your diamond shopping sidekicks. No memorization required. Click the links below to print them to size!

Diamond size chart

One of the most helpful tools is a diamond size chart. While lots of jewelers and jewelry industry sources provide size charts for round diamonds, not as many allow you to compare carat weights across the most popular shapes. 

Ring sizer chart

Especially important when gifting jewelry, a printable ring sizer is a simple way to determine your ring size. 

Keep your diamond sparkling from the day you exclaimed, "Yes!" Get your free how to clean & care for your diamond engagement ring guide.

Alternatively, most jewelers will provide a physical ring sizer free of charge. Great if you’re measuring your own finger, not so great if you’re trying to secretly get the ring size of your significant other.

Ring sizing tips:

  • When considering a wide band, move up a size from your measurement, for comfort’s sake.
  • Your ring size will be about half a size larger on your primary hand (i.e. the hand you write with).

4Cs diamond chart

There’s a lot you can learn about the 4Cs if you have the time and desire to dig deep.

Diamond grading report

Important for appraisals, you’ll want to make sure to get a copy of the grading reports for each diamond you’re considering. While this isn’t something you can do ahead of time, you can learn a little bit about them beforehand.

You can also learn more about diamond reports and services from the Gemological Institute of America (GIA) and from American Gem Society (AGS), the institutions most commonly used for grading.
 

Mobile playbook

Last but not least, we couldn’t talk about portable tools without talking about apps.

GIA created a free 4Cs app, providing diamond knowledge on-the-go as well as access to their Retailer Lookup and Report Check services. (That way you’ll know right away if your jeweler has given you an official GIA diamond grading report or not.)

With all these resources, you’ll be a diamond expert in no time. Be gone, diamond shopping anxiety!

No matter the diamond shape and size you get, make sure it's insured! Jewelers Mutual wants to make sure you can wear your jewelry worry free, which is why situations like loss, damage, theft and disappearances are all covered.

Interested to learn how much it could cost you to have that precious diamond insured? It's less than you think! Click the button below to check your rate.

There are so many benefits of an insurance policy through Jewelers Mutual, but don't just take it from us! Check out what our policyholders have to say.
