History & origins

Sapphire appears throughout royal and religious jewelry. Historic sources include Sri Lanka, Myanmar and Kashmir. The name is linked to the Greek sappheiros.

Choosing a personal gift

Blue sapphire can feel understated when the design is small and simple, or more formal in a prominent setting. For a September birthday, consider whether the recipient reaches for cool neutrals, deep navy or brighter colors. A personal message about friendship or loyalty can make the gift’s meaning specific without making claims about the gem itself.

Check sizing before choosing a bracelet, necklace or ring.

A note on care

Ask about treatments before cleaning. A gentle approach is preferable when you do not know a stone’s treatment history. Find everyday habits in our jewelry care guide.
