Although it was originally impossible to produce diamonds artificially, techniques to do so have been around since the 1950s and have become routine in recent years. Modern techniques can produce diamonds of essentially any desired chemistry or size[citation needed] and can even be made more perfect than naturally occurring ones, synthetic diamonds are genuinely diamonds albeit not naturally occurring.

Rough diamond prices have historically been impacted by the mining companies controlling supply, most notably De Beers.

Polished diamond prices vary widely depending on a diamond's carat, color, clarity and cut, sometimes referred to as the 4 C's. In contrast to precious metals, there is no universal world price per gram for diamonds. The industry refers to price guides such as the Rapaport Diamond Report, the Troy Diamond Report, PriceScope,[4] Ajediam Antwerp Diamonds Monthly[5] and The Gem Guide, which are published weekly, monthly or quarterly. Gemstone specialty organizations have varying standards which can be used to aid in diamond identification and pricing, including GIA, HRD[6] and IGI. These organizations focus on research and education, which they pass on to their members and the public.

The value of diamonds as an investment is of significant interest to the general public, because they are expensive gemstones, often purchased in engagement rings, due in part to a successful 20th century marketing campaign by De Beers.[1][2][3] The difficulty of properly assessing the value of an individual gem-quality diamond complicates the situation.
