What is September’s birthstone?

Sapphire is the traditional September birthstone. It is corundum (Mohs 9) and appears in classic blue as well as fancy colors.

Is London blue topaz a September birthstone?

Not traditionally. Sapphire is September’s birthstone. London blue topaz is a popular, more affordable deep-blue alternative (often listed as a modern December birthstone).

Is London blue topaz treated?

Yes. Most blue topaz—including London blue—is created by irradiation followed by heat treatment. The color is stable in normal wear.

Which is more durable—sapphire or London blue topaz?

Sapphire (Mohs 9) is harder and ideal for everyday rings and bracelets. London blue topaz (Mohs ~8) wears well with mindful care, especially in pendants and earrings or low-profile ring settings.

How do I clean sapphire and London blue topaz jewelry?

Use lukewarm water, mild soap, and a soft brush; rinse and dry. Avoid ultrasonic/steam for London blue topaz and for any fracture-filled sapphires.

Can I customize a September birthstone piece?

Yes—choose metal, hue, cut, size, chain length or band width, and engraving via the Design Your Own collection.
