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.
375CZ most likely refers to the type of metal and gemstone used in the ring. The "375" typically indicates that the ring is made of 9-carat gold, while "CZ" stands for cubic zirconia, a type of synthetic gemstone used as a diamond alternative.
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.
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
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
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!

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.
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.
Mother Nature made the world's biggest diamond.
Diamond is formed from carbon.
Cubic zirconia (or CZ) is the cubic crystalline form of zirconium dioxide (ZrO2). The synthesized material is hard, optically flawless and usually colorless, but may be made in a variety of different colors. It should not be confused with zircon, which is a zirconium silicate (ZrSiO4). It is sometimes erroneously called "cubic zirconium". In other words: It's a fake (man-made) diamond.
