How to read a GIA card? (Easy guide to understand its details)

by Alice Browne

So, I bought this diamond engagement ring last week, right? The jeweler handed me this blue paper with tiny letters called GIA certificate. Looked like alien language. Seriously, who understands “proportions grading” or “fluorescence”? I stuffed it in my drawer first day.

Next morning, coffee in hand, I thought: Nah, gotta crack this thing. Pulled it out alongside YouTube tutorial, but dude kept rambling about carat weight like we’re baking cookies. Switched tactics completely.

The “hold it sideways” trick

Grabbed magnifying glass I use for checking phone screens. Turned the card sideways – boom! Bottom corner revealed diamond shape symbols. Little arrows told me where inclusions were hiding. Mine had feather-looking mark inside. Felt like decoding treasure map.

Didn’t stop there. Top-left corner caught my eye:

  • Date Graded: 06/2023 (fresh!)
  • Carat: 1.02 (bigger than rice grain, smaller than pea)
  • Clarity: VS1 (meant “Very Slightly Included”)

Color showdown

Color section showed letter “G”. Took silver spoon from kitchen for science. Put diamond on spoon edge near window light – looked damn white. Found chart online showing “G” means tinge of yellow only visible if eating carrots daily. Thank god I skipped veggies!

Proportions puzzle

Almost quit at “Depth 60.8%”. Dug out kid’s protractor, started measuring angles. Found crown angle at 35 degrees – not too steep, not too flat. Good for sparkle apparently. Patted myself on back for passing geometry class last century.

Fluorescence mystery solved

Saw “Faint Blue” under fluorescence. Googled like crazy. Turns out: Means diamond glows under UV light like clubs. Tested using sunscreen (SPF 50+). No glow at all. Good. Nobody wants rave ring.

Final victory? Understanding “Cut Grade”. Mine says “Excellent”. Done. Took 2 hours and 3 coffee refills but I owned that blue paper. Jewelers better watch out next time.
