Lab-grown diamonds: what does the term mean?

A laboratory-grown diamond is a diamond that has been produced in a laboratory or production facility. It consists of carbon with the crystal structure of a diamond and has essentially the same physical and optical properties as a natural diamond. Its origin is different and can be identified through professional analysis and appropriate equipment.

Laboratory-grown does not mean the same as diamond-like

CZ and moissanite can also be man-made, but they have a different chemical composition than diamond. Therefore, it is not enough for a piece of jewelry to be described as “lab” or “synthetic.” The name of the stone material tells you what it is.

A product description should distinguish between CZ, moissanite, laboratory-grown diamond, and natural diamond. These terms make it possible to compare products on an appropriate basis. Read our guide to CZ, moissanite, and diamond for a practical comparison.

Consider the specific stone and order

Origin alone does not provide a complete assessment of quality. For a piece of jewelry, you should also consider the design, dimensions, setting, and metal. When offered a specific diamond, it is useful to ask what information and documentation accompany that particular stone.

A material name alone does not document the entire production chain. If origin and production conditions are important to your choice, ask for specific information about the product you are considering.

Choose based on the look you want

Some people want a specific type of stone, while others are primarily concerned with the jewelry’s shape, size, and look. Both are good starting points for an inquiry. Describe what you have in mind and ask that relevant options be clearly specified.

For custom orders, you can contact Iceyard with a reference and budget. The material and stone options that can be offered will be clarified for the specific model.
