Noteworthy question by one of our subscribers:
"Not all diamonds are cut "Excellent" what if it is cut too shallow or too deep?"
You bring up a very good point to further elaborate on the topic:
The formula for round brilliants is based on the ideal measurements that the diamond should have. However, there are weight correction factors for thicker girdles (Slightly thick 1-2%, thick 3-4% very thick 5-6% and extremely thick 7-9%). The additional weight that is held by these diamonds in the girdle needs to be taken into consideration.
Furthermore, there are different formulas for the different diamond shapes (Emerald/Heart/Oval/Marquise/Pear etc.) They all have adjustment factors for the varying length-to-width ratios, girdle or a bulging pavilion.
As for using the formula on round brilliant imitations:
Diamond imitations usually come in ideal measurements to make it look like a real diamond. Once you fake it with a cheap, easy to work on material like cubic zirconia you cut the stones to perfect measurments. As for diamonds: The reason they are not always cut to excellent proportions is mainly to retain as much weight as possible because the material is so expensive. You don´t have this problem for cheap diamond imitations. Given ideal measurements you can always filter diamond imitations.
Muito linda essa esses diamantes Parabéns como que Deus fez as coisas tudo perfeita aqui na terra tão valiosa uma pedrinha dessa lindas 😍😍🙏
right on
Good
What is the name of the device please

Cool!
what does mean this 0,0062 ?
This number is the coefficient used in the formula. The proportions of the round brilliant cut are fixed. Therefore, if you know the density of the material and the measurements of the stone you can calculate the given weight.
Diamant agentur can we identity a cvd using this formula of diameter and total depth ?
Dear Mishal, you are referring to a CVD (chemical vapor deposition) lab-created diamond. Synthetic diamonds are diamonds - they share the same chemical properties and have the same density. Therefore, the diamond test in this video cannot differentiate between synthetic and natural diamonds. Stay tuned for our upcoming video on synthetic diamonds - you will learn how they are made, how they compare to natural diamonds and how they are detected. The different industrial applications are quite astonishing, you will be surprised!
Diamant Agentur GmbH - Diamanten online kaufen thanks for the information
hello i have a stone that i tested with a diamond tester ... can you help me know what kind of stone is it and what are the techniques to identify a diamond and i inform you that i have a lot of stones to test
Which diamond tester do you use? Long distance evaluation is always tricky if you don´t have the stone in front of you. However, we will try our best to assist. Please write an email with the details to: service@diamantagentur.de
