test result
Item no: F5A99582
Inspection City+Date: Antwerp (port name, located in northern Belgium), March 30, 2008.
Type: natural diamonds
Shape and cut: round and bright
Carat weight: 0.58 carat
Color: d (top color)
Cleanliness: VS2 (normal)
Carter: Good.
Polishing: Good.
Symmetry: good.
Translated as "very good" is not really good, just so-so, don't be misled. A truly excellent lathe worker should be excellent in three aspects: cutting, polishing and symmetry. If the round and bright cutting ratio reaches a certain requirement, the result is eight hearts and eight arrows, because the cutting ratio has reached an ideal level.
Size: 5.25-5.30 X 3.3 1 mm
Ranked first: 58% (at the fermentation level, but not up to the ideal level)
Crown height and crown angle: 16% (not bad), 37 (too big)
Pavilion depth and stop angle: 42.5% (rotation), 39.9 (small).
Waist circumference: medium? (This is not good)
Low tip size: medium (this is very bad)
Fluorescence: intense
Is the content of the certificate missing?
And the inherent characteristics of diamonds. number
According to the description of the certificate, this diamond has great defects.
1, uneven cutting ratio leads to asymmetry, and polishing is also affected, which may be the problem of this diamond raw material itself.
2, fluorescence problem, your diamond color grade is already the best, but strong fluorescence will bring bad effects to high-grade diamonds, and fluorescence will make this diamond look hazy and incomplete. If it is intense blue fluorescence, it will make the diamond with low color level look whiter. For diamonds with higher grades, fluorescence has a greater influence.
conclusion
The cutting ratio is generally as large as the low tip, and the color scale is high but fluorescent, so you are right to worry about the fire color, which has a great influence on the fire color of diamonds. You can compare other 3EX cut diamonds without fluorescence. No matter the size, it will be brighter than this.
The asking price is 2W, forget it ~ it's not worth it. If you like, it's a 2W with a machined ring or something. However, you can also cut him two or three thousand because he is not a wholesaler, so you can't cut him as low as 1W5. When bargaining, take the cutting ratio, especially the low tip, the strong fluorescence affects the fire color and so on. The closer to the wholesale price, the better.
