Do Lab Grown Diamonds Last Forever? Durability Guide

Quick answer: Yes, lab grown diamonds last forever in the way that matters: they will not cloud, fade, change color or wear down with normal use. They score 10 on the Mohs hardness scale, exactly like mined diamonds. But "hard" is not "unbreakable." A sharp knock at the wrong angle can chip any diamond, so a secure setting and simple care keep yours beautiful for a lifetime.

Here is what makes lab grown diamonds so durable, where they are vulnerable, and how to protect them every day.

Why Lab Grown Diamonds Are So Durable

Maximum hardness

Hardness is resistance to scratching. Diamond is the hardest natural material, and lab grown diamonds share the exact same crystal structure. Everyday materials like steel, glass and sand cannot scratch them.

Stable color and clarity

A lab grown diamond's color and clarity are permanent. It will not turn yellow, go cloudy or lose its sparkle over time. When a diamond looks dull, the cause is almost always a film of lotion, soap or skin oil, which cleaning removes.

Heat and chemical resistance

Diamonds handle normal household heat and most chemicals without damage. The metal setting is usually more sensitive than the stone.

Hardness vs Toughness: Where Diamonds Can Chip

Toughness is resistance to breaking. Diamond is very tough, but it has natural cleavage planes, directions along which a hard, sharp blow can split it. That is why a diamond that knocks hard against a granite counter or a metal railing can chip, especially on a thin edge or a pointed tip.

Choosing a Setting for Everyday Durability

• Bezel: a metal rim around the whole stone; the most protective choice for active lifestyles.
• Six prongs: extra security for round stones, with a small amount of metal showing.
• Radiant or cushion shapes: cut corners are less likely to chip than sharp princess corners.
• Lower profile: a stone that sits closer to the finger catches less often.

Simple Care to Make It Last

• Take rings off for the gym, gardening, cleaning and moving furniture.
• Clean weekly in warm water with mild dish soap and a soft toothbrush.
• Store pieces separately so diamonds do not scratch other jewelry.
• Remove jewelry before swimming in chlorinated pools, which can weaken gold over time.
• Have prongs checked by a jeweler once a year.
