Diamonds are the best choice for engagement rings.
Even though they have a reputation of being indestructible, they have their weaknesses, which we’ll cover another time. Colored stones for engagement rings have become popular options, due to price, value and sourcing interests. Because engagement rings need to withstand daily wear, the stone you choose needs to be durable enough, so here are some tips for choosing a stone that will last.
A Quick Tutorial: Gemology 101
For crystals and minerals to be considered gemstones, they need to withstand being set into jewelry and worn without being easily damaged.
In the early 1800’s, Frederick Moh, a German mineralogist created a scale for identifying minerals by testing their hardness. By comparing one mineral to another, its identification could be narrowed down more easily. He designated ten minerals as a gauge of hardness for all others to be tested, commonly referred to as Moh’s Hardness Scale.
But, even though it seems like the difference between them should be equal, it’s not.
Diamond is several times harder than corundum. (the mineral name for ruby and sapphire)
This means the only thing that can scratch a diamond is another diamond.

For engagement rings, the ideal choice is a stone with the highest hardness for the color stone you want.
Looking at the chart above, it’s tempting to choose gemstones softer than 8 on the hardness scale, but the higher the hardness, the more durable the stone.
Corundum, or ruby and sapphire, with its hardness at 9, is an ideal alternative gemstone to diamond. Not only is it exceptionally hard, sapphires are available in every color, even colorless.
Here are several exceptional sapphire rings that make excellent candidates for engagement rings.
