Many customers that purchase pearls for the first time do not have a complete concept of the lustre of pearls. When I ask customers what quality pearls they want, they will answer "strong light", "extremely strong lustre", "aurora" and "tennyo". In fact, most customers have no accurate concept and distinguishing methods of the strength of pearl lustre.
What is Pearl Luster? Pearl luster is what gives a pearl its shine and reflective quality. It's what creates immediate appeal when you look at a pearl and contributes heavily to the pearl's overall value. It's possibly the most important pearl value factor.
My personal opinion on the evaluation criteria of pearl luster is as follows:
⭐Extremely strong A: The reflected light is particularly bright, sharp, uniform, the surface is like a mirror, and the image is very clear.
⭐Strong B: The reflected light is bright, sharp, uniform, and the image is very clear.
⭐Medium C: The reflected light is bright, and the image of the object can be seen on the surface.
⭐Weak D: The reflected light is weak, the surface can see the object, but the image is blurry.
How do laymen see the strength of pearl luster, I will make a summary of my own:
⭐Strong lustre: The contours of the face and facial features is clearly visible.
⭐Medium lustre: The contours of the face are visible, and the facial features are blurred.
⭐Low lustre: The outline of the face is blurred and visible.
From left to right, they are: strong lustre, medium lustre, and low lustre. The third picture have the most obvious contrast effect. Therefore, the backlight is easier to distinguish the lustre of pearls.
The above is the luster comparison of freshwater pearls, white south sea pearls, golden south sea pearls, and Japanese akoya pearls.
I also took some pictures of other kinds of bright pearls for your reference.
