Diamond vs. Platinum: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Published on December 14, 2023
Diamonds are hard, crystalline forms of carbon used in jewelry and industrial applications, while platinum is a dense, malleable, and corrosion-resistant metal used in jewelry, automotive, and other industries.

Key Differences

Diamonds are naturally occurring crystalline forms of carbon, renowned for their hardness and brilliance. While, platinum, a chemical element, is a precious metal known for its high density, malleability, and resistance to corrosion.
In jewelry, diamonds are prized for their optical properties like clarity, cut, and carat weight. Whereas, platinum is valued in jewelry for its lustrous sheen, hypoallergenic nature, and durability, often used as a setting for diamonds.
Diamonds are the hardest known natural material, used industrially for cutting, grinding, and drilling. However, platinum, due to its high melting point and catalytic properties, finds extensive use in automotive catalytic converters and chemical industries.
The formation of diamonds occurs deep within the Earth under extreme pressure and heat, and they are brought to the surface by volcanic eruptions. Platinum is obtained through mining and is often found in its native, uncombined form in alluvial deposits.
In terms of market value, diamonds' prices are influenced by the gemstone market, driven by rarity and demand. Platinum prices are subject to the precious metals market, influenced by industrial demand and mining supply.
