A Blue sapphire is the most common sapphire color and the easiest to color-match when sourcing a sapphire for engagement rings.

A pale blue sapphire can range from shades of sky to almost colorless, like white sapphire engagement rings. A favorite of designer Melanie Casey, soft, icy blue sapphires never last too long in the collection.

Bridging the gap between purple sapphire and blue sapphire is the violetish blue sapphire, which radiates vividly. 

The coveted Montana sapphire engagement ring comes in many shades, but the classic Montana sapphire is teal, combining blue with greens and yellows to create something oceanic and unique to this region of the world.

A green sapphire engagement ring is another popular choice because of its depth of color, ranging from a light and grassy yellow green sapphire to a deep forest green sapphire.

Purple sapphire or pink sapphire engagement rings are also beloved by many, with shades ranging from deep moody purples to rosy pinks and pastels to peach sapphire engagement rings.

Pink sapphire engagement rings are also beloved by many, with shades ranging from deep rosy pinks to soft and subtle, like warm peach sapphire engagement rings.

Sapphires can also come with multiple colors in a single stone. Bicolor sapphires can either appear to be different colors in different lights, or can be half one color and half another with an ombre effect bridging the boundary between them.
