As output we obtain three spherical functions vp, vs1 and vs2 representing the velocities of P, and fast and slow S-waves respectively in dependency of the propagation direction.

2015年5月7日 · Today, we’ll look at the plotting diagram that appears on GIA Diamond Grading reports and GIA Colored Diamond Grading reports to better understand how these reports …

2023年3月3日 · Chart 04 - Distribution of Price by Color As diamond prices depend on various variables. I want to explore the correlation between carat and price in colorless diamonds (D, …

What is a VS2 Clarity Diamond? VS is taken from the clarity scale created by the GIA and stands for ‘Very Slightly Included’; it is split into two grades, VS1 and VS2. Below you can see how …

2023年7月3日 · 无论你利用动能定理 F\Delta s=\Delta\left (\frac {1} {2}mv^2\right)=mv\Delta v ，或者冲量定理 F\Delta t=m\Delta v ，都能得到. 这极容易得到： 考虑到初始时刻 s (0)=0 ， 第三 …

VS2 is often seen as the holy grail of diamond clarity. Not so included as to be noticeable to the naked eye, while just included enough to cost far less that its fancy counterparts up the scale.

2022年3月25日 · SI (slightly included) and VS (very slightly included) are two categories on the GIA diamond clarity scale. Each is broken down into two grades: SI1, SI2, VS1, and VS2. The …

For example, a SI2 diamond may show only a few clarity marks, but the severity can only be seen in its photograph. Also, a diamond plot can possess a lot of markings, but it could only be …
