I has just found a round shape diamonds with E color SI1 in a shop, which showed three long twinning wisps in its GIA cert. However, I could not find them in the diamond under 10X manified glass. Pls advise whether twinning wisps are invisible even under 10X. Does it happen in VS1 or VS2?

HI,

你好!有時淨度是SI1,有些內含物時肉眼會看到,如果你想肉眼看不到,最好都是選擇VS2以上,
相對來說通常要用10倍放大先看得到.
