Nice, quality black gua sha. Too many noticeable nick/pock marks.
Don't know if this is black jade, seems more likely to be obsidian. In general, the stone is black with no blending or gradations exhibited: it's totally black (thus the guess that it's actually obsidian). The stone is fine, with a nice thickness. It's fairly well polished with nice shine and associated smoothness. However, there are too many nick, pock marks on the gua sha. These appear as white marks. It's possible that they're post manufacturing damage, since the marks are white, possibly from slamming into another stone or object.<br />In the attached photos, two pictures show some of these marks, which will be clearly visible, the white marks contrasting with the black stone.<br />These defects/flaws negatively impact the rating. So, while the black gua sha is a nice product that closely matches the product details, it receives a 4 star rating.
Rating: 4 stars
