GIA 4Cs Guide
Free AppAbout GIA 4Cs Guide
GIA’s 4Cs app features video and interactive tools that teach consumers about how GIA grades color, cut, clarity and carat weight. It explains GIA’s D-to-Z color scale and how diamond color can affect value, GIA’s clarity scale and how diamond clarity can affect value, the factors that affect a diamond’s cut grade and the origins of the carat system.
Interactive tools show:
• How diamond color changes across the GIA D-to-Z Color Scale
• Typical inclusions and blemishes at various points in the GIA Clarity Scale
• A diamond’s anatomy and how various parameters influence a diamond’s cut grade
• How a diamond’s size changes by carat weight and enables consumers to compare the sizes of different diamonds
• An interactive GIA Grading Report Anatomy – to help consumers understand the different elements of a GIA report
Additional features include:
• Retailer Lookup allows consumers to find retailers that sell GIA-graded diamonds and/or have GIA-trained sales associates. Search by:
- Sells in-store and/or online
- Sells online only
• My Diamond Wish List that allows consumers to keep a record of the diamonds they’ve seen and considered by entering any diamond’s relevant information, including its report number, 4Cs information, price and the retailer’s address and contact information in their wish list.
• Information on fluorescence, common diamond treatments, synthetics and simulants.
• Direct Access to GIA Report Check (network connection required) - GIA’s online database of diamond grading reports and Diamond Dossiers. Consumers can verify the contents of a GIA report and view a PDF version of that report simply by entering a GIA report number and carat weight.
What is new in Version 1.4:
• GIA grading scales updated
• GIA report anatomy updated
• GIA 4Cs videos updated

Tried to download onto my tablet but the app doesn't even show up in the Play Store. Way too small to be of any use at all. I am a GG from GI A, and this app is completely useless. Too bad.

Edit: only slightly better in landscape mode, but still too tiny to be of good use. --- I'm guessing that this app would work if I could read the text on the screen of my GS4, but it's way too tiny to read. Imagine if a full Web page on your computer was shrunk down to your phone's 5-inch screen without adjusting the font size or page layout. No apparent settings to adjust this. Pretty useless app as is. Fix this and I'll be glad to regrade it here.

This app has a lot of potential, since all the information one needs is contained in it. If only it wasn't so undersized. Even the carat weight example is about half the size of a real round carat of around 6.5mm diameter, on my S7 Edge. I cant find a way to zoom in on the colour and carat size examples which effectively makes this app obsolete unless one is prepared to use a magnifying glass on the mobile phone.
