List of diamonds

Notable individual diamonds

Diamonds occur naturally and vary in size, color, and quality, so the largest of a particular color may not be large in absolute terms, but may still be considered very desirable. Diamonds may also have high valuations in sale prices, and large ones invariably have a noteworthy ownership history. There is no agreed-upon measure of a large or a high-quality diamond, and new ones displace others on any subjective list, so strict inclusion criteria for notable diamonds are not attainable.
