With the same clarity level, diamonds may actually be completely different. However, as far as I know, no jeweler will tell you this secret.
The word flaw is actually very general and has many meanings.
Diamonds are minerals produced underground. In this case, after cutting, the inclusions and marks on the inside and surface of the diamond are wrapped in it before mining. The clarity grade of diamonds used for gemstones accounts for less than 10% of all mineral resources, and it is very rare for diamonds with a clarity grade above VS. It is conceivable that there are no two identical diamonds in the world. Therefore, taking the mark belonging to this diamond as the best witness to identify this diamond is to maintain the correctness and objectivity of clarity classification.
So there is absolutely no need to blindly pursue high-purity diamonds.
Believe it or not, under the same conditions as 3C, a diamond with a clarity of VVS 1 may actually be inferior to a diamond with a clarity of VS2.
This depends on the type of defect: cleavage: cleavage, what is cleavage? -For example, it is easier to cut bamboo vertically than horizontally, even if it is broken; It takes a lot of effort to cut a hole horizontally, that is, cleavage. If your diamond defect is this, congratulations, you will suffer. Today is VVS 1, and tomorrow it will be SI2 if you accidentally knock on the table, haha.
Feather crack: Although the name is nice, it is not much better than the one above. It's just a brittle crack inside the diamond, which looks like a feather, and VVS can easily become SI. But there are many diamonds with this defect. If your diamond is Gia's, have a look. If so, congratulations. Basically, you're wearing less. Take good care of it.
Needle tip: The needle tip is actually a tiny mineral inclusion. If there are few such defects, it will only affect the clarity level, but it will not actually affect the fire color. Of course, more will still have an impact.
Crystal inclusion: crystal inclusion. For example, your diamond is wrapped in a crystal. Of course, this crystal is smaller than the needle tip. Similarly, as long as it is not excessive, the existence of this defect only affects the clarity level of writing, and has little effect on fire color.
Dark crystal: black crystal. Different from the above, the crystal was replaced by opaque small black stones. ....................................................................................................................................................
Knot: The surface crystal, the crystal is not completely wrapped, and half of it is exposed-this ... is a matter of opinion.
Clouds: Clouds, very small inclusions, mainly nitrogen and hydrogen, are concentrated in an area inside the diamond and look like clouds. Less has little effect on the fire color, but more still has an effect.
Needle: Needle, do you know hair crystal? If I don't know, I'll find a water-spotted bamboo to literacy. If it's blonde, I'll grab it even if it's a P-diamond.
Internal texturing: twin Wisp, texture center, these three concepts are better explained together. The basic explanation is vein texture. What is vein texture? It can be understood as something similar to a growth line with rubies and sapphires. For example, driving in summer, the road ahead is very erratic, like a mirage, which is the refraction of light. This kind of flaw is also natural, which is a grain rather than a crack. Its existence basically does not affect the clarity, but it can greatly affect the diamond price, because the fire color is affected, and the light refraction is affected ~ If you see that the clarity of a diamond is VVS 1, 3EX, D color or large particles, but the price is so cheap, then don't doubt it, you must have encountered this kind, and you will buy it or not. Haha, laser drilling: this kind of flaw is not natural, that is, the diamond wrapped with small black stones is drilled out by laser, the small stones inside are burned, and then glass or silica gel is poured in to improve the fire color. The principle is similar to that of Emerald B. Don't buy this for the same reason as Emerald B.
Fragments (small) (large): cavities: serrated nature: concave nature rough surface scratches: sulfur injuries are all injuries strictly speaking, and their shortcomings are similar to cracks, so try to avoid them.
There are still some injuries, so I won't introduce them one by one In short, if you see these English words, you should avoid buying them: Extra Facet, Natural, Pit, Nick, Scratch, Polish Lines, Abrasion and Burnmark. In any case, you should not work.
In addition, the surface grain is explained separately. This is the surface texture, which is the same as the internal texture mentioned above. It has little influence on clarity and great influence on price. This is a dangerous killer and should be avoided.
That's basically all. Under the same level of clarity, it belongs to injury, crack and stripe, which has a great influence on the price of diamonds and is in danger of aggravating or even cracking. Therefore, try not to buy such a diamond, even VVS, and cut it! Defects belonging to internal inclusions depend on whether they affect the fire color of diamonds. If it is not big, even if the clarity of writing looks low, it is very worthwhile.
These things are unknown to laymen, even many people who have sold diamonds for many years, while experts, mainly jewelry appraisers hired by jewelers, know them, but they are absolutely silent.
Does everyone understand now? These are things that a jewelry appraiser will never tell you! As the old saying goes, diamonds are likely to be bought for a lifetime. Everyone should carefully calculate every penny in the bag, and don't be slaughtered.
