The term 'prototype' and the term 'diamond chips' aren't really connected, since diamond chips are the result of cutting and polishing a diamond stone.
Prototype implies something designed and fashioned; diamond chips don't fit into that definition.
Diamond chips can always be used for finishing and polishing other diamonds.
Diamond chips do have some value they are used in high performance commercial drills.
Your answer depends on the chips. Some chips can only be used as abrasives to cut and polish other diamonds; other chips -- rather large chips -- can be cut and polished into smaller gemstones. Every diamond is valued individually by its cut, clarity, carat weight and colour.
The only difference is that C does not use nor require prototypes. C++ does because all functions and types must at least be declared, if not defined, before they can be used.
Thine Electronics sell parts used to produce chips, such as LED drives, LEDs, multiple different types of recievers and transmitters, and chips to put into your motherboards.

Diamond is usually a good insulator, and as it also has the highest thermal conductivity, these properties are used as a substrate under semiconductor chips for extracting the heat. But some blue diamonds are a semiconductor, due to boron trace contamination, and these are used as a semiconductor material.
Test something that's been designed in a practical way.
It is possible to look at prototypes of commonly used circuit boards at Thomas Net, Analog Static, EI Connect, Wise Geek, How It Works, and e-tool Smith.
Mcain oven chips. LOL
One word pair that can be used for 'chips' is "fish and chips."
Silicon is used in computer chips.
