Can Water Break Diamonds?
Diamonds are known for being extremely hard. But can water break diamonds?
Diamonds are the most scratch-resistant material on the Mohs scale but are still susceptible in other respects. Gafla Jewellery presents the unexpected possibility that, in some situations, water might harm diamonds.
Hardness vs. Fracture Toughness
Despite their extraordinary hardness, diamonds are fragile. Tensile stress causes brittle materials to break readily. Diamonds are prone to fracture when internal or external pressures surpass their low fracture toughness, which is often approximately 2 MPa·m¹ᐟ².
Can Water Break Diamonds?
Yes. Water can break diamonds under force, expansion, or pressure. However, diamond jewelry is safe to wear near water in daily life.
Freezing Water Inside Diamonds
According to experiments and scholarly debates, the growing ice (up to around a 9% volume increase) may impose tremendous pressure if water is held within a hollow diamond and later freezes. If there are internal defects and thin walls, ice expansion might break the diamond even if sturdy materials surround it.
Pressure, Temperature, Phase and Ice Variants
Water may create denser ice phases that restrict expansion at extremely high pressures. However, the diamond must be thick and perfect to cause that. Microscopic inclusions that concentrate freezing stress and can cause cracks are frequently seen in real-world diamonds.
Surface Damage and Water Jet Cutting
High-pressure water jets, particularly abrasive-enhanced streams, may physically erode or cleave diamond surfaces. These techniques demonstrate how water may harm even extremely durable materials.
The Bottom Line
So, can water break diamonds? Yes - under controlled situations.
Water may shatter diamonds, but only in exact situations, such as freezing inside cavities or touching abrasive streams or high-pressure water. Exposing perfect, solid diamonds to liquid water will not cause them to break. Still, even diamonds lose their fabled indestructibility when force, freezing, or confinement are applied.
