Shattered Illusions: The Top Two Myths About Diamonds You Need to Stop Believing

Many clients believe that because a diamond is the hardest natural material on Earth, it cannot be broken. This is a profound misunderstanding of gemology.

In material science, there is a distinct difference between Hardness and Toughness . Hardness refers to a material's resistance to scratching. In this category, a diamond scores a perfect 10 on the Mohs scale, meaning only another diamond can scratch its surface.

However, Toughness refers to a material's resistance to breaking, chipping, or cracking. Diamonds are formed with specific atomic structural lines known as "cleavage planes". If a diamond receives a sharp, forceful impact at the exact wrong angle—particularly along the girdle (the outer edge of the stone) right next to the setting prongs—it can absolutely chip or fracture.

There is a pervasive industry belief that buyers must aim for exact "magic weights," such as a 1.00 or 2.00-carat stone. The traditional warning given by old-school jewelers is that if you buy an exact 1.00-carat diamond and it chips, repairing (repolishing) the stone will drop its weight to 0.99 carats. This drop causes the stone to fall into a lower pricing bracket on the Rapaport diamond price list, drastically reducing its financial value.

While it is entirely true that dropping below the 1.00-carat mark severely impacts a diamond's resale value, the act of a diamond chipping is statistically very rare. The real danger of the 1.00-carat trap happens before you even buy the stone.

Diamond cutters are highly aware of the massive price jump at the 1.00-carat mark. Consequently, they will often intentionally compromise the ideal proportions and symmetry of the Cut just to retain enough raw weight to hit exactly 1.00 carat . Buying a perfectly cut 0.90 or 0.95-carat diamond is almost always a smarter, more beautiful investment than buying a poorly cut 1.00-carat stone that lacks brilliance simply to satisfy a round number on a certificate.

Knowing that a diamond can theoretically chip shouldn't make you afraid to wear your engagement ring every day. It simply highlights the profound importance of expert craftsmanship.
