The result of cutting
After cutting the stones, we always estimate the stones ourselves before shipping them to AGS. These were the results.

In weight, we ended up with a total finished weight of 48.94 Carats, thus a yield of 35.40%, which was a tad higher than the expected 34.65%.

In colour, we estimated the final colour (in our figure-system) at 4.53. We had estimated a colour of 4.58. Roughly, we could say that we ended up exactly with the average G-H-colour, which we had predicted.

In clarity, we had predicted a clarity of 6, which stood for SI1 in our system. After cutting, we estimated the final clarity at 6.21, thus a little lower than SI1.

All in all, we were very happy with the outcome, although the slightly lower clarity already lowered the $-outcome of our parcel by 6%. Still, we did consider this a good buy, especially since we are very comfortable with our estimates before sending to AGS, and we generally get the same results on our grading reports.
