VS2 Diamond: What Is Important To Know - The Diamond Pro
2024年1月15日 · A VS2 grade comes in around the middle of the overall grading scale for diamond clarity, but realistically indicates a high-quality diamond that is very close to looking flawless when viewed in normal conditions. In order to understand what a VS2 diamond is, it’s important to know the basics of the diamond clarity chart.
H Color Diamonds: Near Colorless and Great Value for Money
2024年8月30日 · H color diamonds are 2nd in the “near-colorless” range of the GIA color scale, meaning they appear almost colorless when viewed with the naked eye, but could show a slight yellow tint when viewed under magnification by an expert gemologist. A 1 carat H color diamond typically starts around $5,500.
钻石等级？ - 知乎
2018年9月26日 · H色是公认的钻石颜色分水岭，从H→D钻石颜色逐渐变“白”，从J→Z钻石颜色逐渐变“黄”。 因此选购钻石时，我们建议选择H色及以上。
Sub‐Millimeter‐Scale Monolayer p‐Type H‐Phase VS2
The honeycomb-like structure of H-phase VS 2 with broken inversion symmetry is confirmed by spherical aberration-corrected scanning transmission electron microscopy and second harmonic generation characterization. The phase structure is found to be ultra-stable up to 500 K.

First-Principles Studies of the Magnetic Anisotropy of Monolayer VS2 ...
2016年11月23日 · In this work, we perform first-principles calculations to study the magnetic anisotropy of monolayer VS 2. The magnetic preferential axis for H-VS 2 is in-plane. Meanwhile, the magnetic anisotropy energy (MAE) for T-VS 2 is so small that can be ignored. The microscopic origin of magnetic anisotropy in monolayer H-VS 2 is our focus in this research.
