How to Choose a Gemstone Engagement Ring

Colored gemstone engagement rings have become a popular alternative to traditional diamond solitaires — but choosing one involves a few extra considerations worth understanding before you buy.

Durability Matters More Than You'd Think

The Mohs hardness scale measures a gem's resistance to scratching, but daily-wear durability also depends on toughness (resistance to chipping) and stability (resistance to damage from heat, light, or chemicals). Sapphire and ruby (both corundum) are excellent choices for daily wear at 9 on the Mohs scale. Emerald, opal, and tanzanite are softer or more included, and while all can be worn as engagement rings, they benefit from protective settings — bezels or halos — and a bit more care.

Setting Style Follows the Stone

A stone with natural inclusions or fractures, like emerald, is safer in a protective bezel or halo than an exposed prong setting. Opal, being both softer and more sensitive to knocks, is best set low and protected. Harder stones like sapphire have more flexibility in setting style, from classic six-prong solitaires to more exposed east-west settings.

Deciding Between a Finished Ring and a Configurator

If you already know exactly which stone and setting you want, a finished ring is the faster path. If you'd rather choose your center stone first and then match it to a setting (or vice versa), our configurator walks you through that decision with a running total and a persistent summary, so nothing is a surprise at checkout.

Sizing and Timing

Most finished rings ship within about a week; configured pieces typically take two to three weeks to manufacture, since the setting is made to order around your chosen stone and size. If you're working toward a specific date, order with that lead time in mind.
