Hey, I want to buy a pair of diamond earrings for my child as her birthday present. So cooool, right?! But after browsing some online vendors like Zales, etc., I found that some items do not offer a diamond grading report to detail the 4Cs.

Just wanted to know if these earrings faulty, and how to ensure I'm buying genuine diamonds and they're good stuff...

@craigbaker The reasons why the vendors do not provide grading reports for diamond earrings can be broken down into these:

  • The carat weight of the center stone is so small and does not reach the lower limit that grading laboratories require to offer a grading service. For example, GIA generally grades diamonds weighing at least 0.15 carats. (Here's their service page for your reference: https://www.gia.edu/gem-lab-service/diamond-grading)
  • It's simply not worth the investment in grading reports for diamonds on the earrings, considering a grading report can cost a minimum of several dozens of dollars while the price of these small earrings is a mere $100-200.⚖️
  • The vendors may try to deceive you, and the "diamonds" may be just simulants with similar looks.

The simple way for regular consumers to purchase items without reports with confidence is to buy from reputable vendors like Shane Co., James Allen, Blue Nile, DiamondStuds.com, etc. Alternatively, turning your eyes to lab-grown diamond earrings and diamond simulant earrings can broaden your choice and make the best value for your money -- more considerable carat weight -- and/or strong fire effect (if you opt for CZ earrings).

Awesome! Thanks for your detailed answer @stevenkwok! But what are CZ earrings you mentioned at the end?

CZ is short for cubic zirconia -- a synthetic gem positioned as a great simulant to diamonds. If you had a tight budget, I suggest having a look at CZ earrings. They are very affordable, and you can easily get a pair of a higher carat weight. They're also a fantastic option for those chasing a stronger fire effect on a colorless gem.

However, diamonds undoubtedly have unparalleled value and symbolism.
