A diamond is NEVER made of zircon, they can only be made of carbon.
It is trivial for an appraiser to distinguish a cubic zirconia "fake" from a diamond and correctly determine the value.
A ring stamped NV11 likely does not have a real diamond. The stamp does not indicate that it is made with genuine diamonds. It's always best to have the ring appraised by a professional jeweler to determine the authenticity of the stones.
Chemical symbols can show that cubic zirconia (ZrO2) is not diamond (C) by indicating the different elements present in each compound. Diamond is composed of carbon atoms, while cubic zirconia is made of zirconium and oxygen atoms. The chemical formula of the two materials clearly demonstrates their distinct elemental compositions, revealing their differences in atomic structure and properties.
No, a simulant diamond is not a real diamond. It is a material that mimics the appearance of a diamond but is not made of the same physical and chemical properties as a natural diamond.
a diamond is made from heavily compressed carbon.
Cubic Zirconia is a synthetic man-made material, while Zircon is a natural substance dug from the earth. Also, real Zircon is more rare and expensive than cz (cubic zirconia), but it's best to take your pieces to a qualified jeweler, as 'site' appraisal of jewelry can be tricky for the consumer if you don't know how to tell the difference (and some appraisers can cheap you as well, one reason to learn about these 'gems' on your own if possible, even take a jewelry course or two.).
CZ stands for the company that made the ring. A "CZ" can also be cubic zircon that is a man made gem/diamond.
A ring stamped NV11 likely does not have a real diamond. The stamp does not indicate that it is made with genuine diamonds. It's always best to have the ring appraised by a professional jeweler to determine the authenticity of the stones.
Jet is a material made very popular by Queen Victoria, who wore it exclusively after the death of Prince Albert There's a good possibility it might be valuable, have it appraised
Several transparent medias do at some extend, made the light to bend, to slow the speed of light to a certain degree -or refracts-); water, paper, glycerin, immersion oil, glass (crown), glass (flint), zircon, diamond, lead sulfide
You clean a man made diamond the same way that you would clean any other diamond. Chemically speaking there is absolutely no difference between a diamond that is made by a man made process and a diamond that was made by a geologic process.
art made with diamonds!

One can have an antique doll appraised at a local antique dealer. They will be able to check the dolls for markings, which will tell when the doll was made and who manufactured it. From there, one can start the process of having them appraised.
Insofar as gems are concerned, there are several semi-precious and outright fake objects that can be 'alternatives' to a diamond. Quartz, white sapphire, zircon, moissanite, and glass. Insofar as industrial use for diamonds -- about 80% of all diamonds mined are industrial diamonds, there are no natural substitutes. However, there are man-made, lab-created alternatives: man-made diamonds.
Mother Nature made the world's biggest diamond.
Diamond is formed from carbon.
Diamond is a gemstone made up of only carbon atoms. Its structure and composition give it unique properties, such as its exceptional hardness and brilliance.
