The different types of flaws of jade.

In addition to color and transparency, there is another important factor affecting the value of jade. If it comes to flaws, you should distinguish whether it is created naturally or a crack, that is really worth considering the day after, but for those flaws that affect just aesthetics, the crack that will affect the firmness. This is a cracked bangle, we can see it would break one day.

During its formation, Jadeite experienced countless geological movements. Numerous squeezes, crashes, and pulls have caused the jadeite crystal itself to be broken, creating cracks. Some of the cracks healed gradually with time’s precipitation and restored the original firmness but left scars. It is the healing crack, usually called the stone born lines. This is a born stone line that is inside the jade bangle.

Natural lines of stone are often inside the stone, and can’t be felt with nails. worth tens of millions jades, such stone lines are inevitable. Instead of discarding it, we have to find the right way to carve them enlarge the value, we use the direction of the crack to carve a crack-like pattern on this bergamot, so that the crack looks less obvious, which also makes jade show the greatest value.

Even the finest collection-grade jadeite will inevitably have the existence of small stone lines, The born stone line is a testament to the thousands of years, so do not pay much attention to the flaws, but rather enjoy the natural characters.
