Hello, this is Kate. I see this diamond as a GIA graded 1.23ct RD J SI1.

This J color will show a bit of warmth. Based on the video I would ask the retailer if it has a tint, looks a little brown. If so, I would pass on the stone. 

This SI1 looks great!

All of the proportions, finish and fluorescence are within ideal ranges.

Anytime there is strong fluorescence or higher, be sure to confirm any side effects with the retailer. There is the potential for a milky fog in the stone in bright lighting, especially sunlight, not always visible in a photo.

You’ve selected a round diamond, like 0% of our users. Learn more about what to look for in round diamonds here.

Cut is the most important factor. When an experienced gemologist picks up a diamond grading report, their eyes go to very specific values. They are looking to see if these fall within the desired ranges. Seemingly unimportant values like the depth percentage have a large effect on how your diamond will sparkle - and these values differ for each shape.

Follow the checklist prepared by our gemologists to see how your diamond fares. If it misses by a little bit on one or two, that’s fine, but we recommend trying to find a stone that passes on all:

Your diamond is graded J color (Near Colorless), and you can read more about J color diamonds here.

Color is graded beginning with D (Colorless). Learn more about diamond color here. The market prices colorless diamonds higher as they are rarer, but some people prefer warmer colored stones.

Your diamond is graded SI1 clarity, which stands for Slightly Included 1. Read more about SI1 clarity diamonds here, or learn more about diamond clarity in general here.

There are minimum clarities our gemologists prefer for each shape, but beyond that clarity is a matter of budget and preference. People typically aim for an eye clean stone. Also, our gemologists have certain deal-breakers when it comes to clarity. For example, our gemologists always avoid stones with a cavity, because with one wrong hit your diamond can crack.

Use the checklist below to ensure your diamond passes. Consult us before purchasing to see if any other nuanced issues are present:
