Bloodstone quality evaluation method :

quality

The quality evaluation of bloodstone is mainly considered from the following aspects:

1. "Blood": The quality of "blood" is determined by four aspects: blood color, blood volume, concentration and blood shape. The quality of the bloodstone requires that the blood color is bright and positive, but also to live, and to be melted into the "ground", the amount of blood should be more, the more the better, and the thicker, the blood shape is better with bloody blood, point Blood is second.

2. Clarity: It is better to use no flaws or cracks. The presence of flaws and cracks can affect the quality of the bloodstone.

3. “Ground”: The quality of “ground” is determined by its four elements: color, transparency, gloss and hardness. The color of the "ground" is required to be deep and elegant, and requires "ground" to be translucent, with a strong waxy luster and low hardness.

Affecting price factors

First, the blood color; the color of the bloodstone from the bright red is the most expensive, the second is the red, dark red is poor. The bright red is also called "blood-activating blood"; the dark red is called "dead blood" because it is like blood coagulation;

Second, the amount of blood; generally speaking, the content of fresh red blood is more than 30% for high-end products, more than 50% for fine products, more than 70% for treasures, the blood content is not the more the better, such as all blood, that is a piece Cinnabar is not a bloodstone. For the finished seal; the six-faced blood is the top grade, called "full house red"; the four-five-faced blood is genuine; the third and second sides contain blood, and the single-sided blood is the next product.

Third, the blood shape; there are star-shaped (point blood), strip-like (blood), block (block blood) three. The blood shape evaluation should grasp the distribution characteristics of "blood" in the stone. If the cloud is foggy and constitutes an abstract figure, the value of the bloodstone will increase.
