Which is the chemical formula of such kind of diamonds? Really they are made by carbon only? Is there any certificate about?

yes there is when you get this ring it comes with a certificate card and number my wife loves this ring

They are made from carbon and it does come with a certificate, it has a card explaining the chemical formula as well. The diamond and band look really great.

Hello, I actually received a certification with the ring. Color grade DClarity VVSI

no...just metal. if you know where you dropped the diamond your best beat it the get a fine screen and sift the dirt.. you will find it.

As far as I know, the only ingredient is human grade vitamin C. I would contact the company just to make sure if you have any other questions or concerns.

It is safe for all gemstones including CZ diamonds. It is all natural ingredients.

Depends on the gem in question. This is only intended for diamond testing. Other gems have other methods of testing.

I do not have ceramic knives, so I really don't know. BUT diamond is the hardest substance, I would think yes, but you should contact the manufacture of you knife to find out for sure.

I measured one of them @~1/16" thick. "high carbon" and "high carbon stainless" are not the kinds of terms I would look for. These knives are VG-10 Steel, which is a high performance stainless steel- with what could be called a "high carbon" content of ~1%. The chromium (@15%) is what makes it stainless, and in this case, vanadium, molybdenum, cobalt, and manganese factor into the overall steel equation. It holds an edge remarkably well, while offering superior corrosion resistance. I put mine to a honing steel somewhat regularly, and sharpen maybe ever 3 months- but I like to maintain a shaving edge on these knives. They take the edge easily and hold on to it fantastic (using DMT diamond and then ceramic stones to polish). I have to say, I think it really depends on your own habits. These probably aren't ideal if you like to cut with more tight gripped downward pressure than a balanced slice. They're exceptional performing knives, but I think they're meant as more of a finesse instrument than a chopping tool. In my opinion, the balance and weight is great, the quality of the construction is obvious, and these are some of the best kitchen knives on the market. With fine diamond stones (I prefer DMT) and ceramic, they are very easy to maintain (a few minutes is usually all it takes to get it back to a scary shaving edge)-- but I wouldn't use them as cleavers in any sense whatsoever. If you're into finesse and slicing over brute-force chopping, I couldn't recommend these higher.

Using an actual measuring spoon (1 tsp), the individual cubes hold 2 tps, 3 tsps fill cube to the brim. Looks as though 1 tsp will still capture the facets of the "diamond" shape, just won't be thick.

I can only guess that the other 1% is composed of "impurities" such as manganese. It would be virtually impossible to market something as 100% pure iron.Wish I were of more scientific help.

The carbon appears to be pressed / extruded into tube form and looks much like spaghetti. It is also very hard which might indicate low porosity. It also does not come in the bag that is pictured. There is minimal dusting when rinsed and I believe this is due to its hardness. I use it in my freshwater aquarium and it has been working well. I have proved this by performing full spectrum testing of the water.

They work just fine in my designer diamond and I know people who use them, trouble free, in the Ruby. BTW, I find them more economical to use, in the long run, than winding my own. Wish I had started using them earlier

It is stainless, not carbon. Holds as well as any other stainless. Also judge by the price. Not the highest grade of stainless. Frankly just bought it for it's looks.

I don't know specifically, I have. Diamond bright finish. By the way, this particular stopped circulating after two months. I would not recommend it.

They are graphite. Manufactured in 2012 I believe. One of the best purchases I've ever made!

no, it will only tell if it is a diamond. however, i tested mossanite and it tested like a diamond.

I believe it's carbon. I've had mine now for a while and it's still my favorite.

I am not certain, but I believe it is a grayish color. Don't know about the diamond shape color.
