Hi! I have taken a look at the 1.50ct J SI1 GIA graded Oval brilliant diamond (#1335337412) you sent our way.

J is the last grade in the near colorless and will show a bit more of a noticeable warmth. Having the medium fluorescence is nice as this can help make it appear whiter.

SI1 may or may not be eye clean so it is best to see an image before making any decisions. You will also want to check for any darker bow tie as this is more common with ovals.

With top grades in polish and symmetry, all facets are angled well and working together to create lots of fire. The depth percentage is a tad high but not a big deal!

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:
