All About September Birthstone Jewelry: Sapphire

Although diamonds will never give up the top spot, colored gemstones keep gaining ground, and sapphire is the one people come back to. Our September birthstone scores a 9 on the Mohs hardness scale, with only diamond ranking higher, which is why it turns up in pieces meant to be worn every day rather than saved for occasions.

Whether you are shopping for a September birthday or simply drawn to that unmistakable blue, we can help you find a piece worth passing down. Browse our sapphire jewelry and read on for the story behind the stone and a few straightforward ways to wear it.

Sapphire as the September Birthstone

Sapphire has carried meaning for centuries. Persians treasured the stone as a protective talisman and tied it closely to royalty, and that regal association has never really faded. Today sapphire still reads as a symbol of wisdom and constancy, and it anchors our colored gemstone collection.

The most famous sapphire of all is the blue sapphire and diamond ring worn by Princess Diana and now by Kate Middleton, a single piece that did more for the stone’s place in modern romance than any campaign could. If a sapphire center stone appeals to you, our guide to blue sapphire engagement rings and wedding bands covers that decision in full.

Styling Sapphire Fine Jewelry

One of the pleasures of sapphire is how readily it adapts. For a cooler, crisper look, pair blue sapphires with white gold or platinum. For something warmer, set them against yellow or rose gold, which pushes the stone toward navy. From there it is all pairing: stack a sapphire band with what you already wear, or let everyday earrings do the work.

On the hand, the choice is mostly about how much room you want the stone to take up. These three run from a band you could wear under anything to one that is the whole outfit.

The Robbins Brothers Difference

For more than 100 years we have helped guests choose stones they intend to keep, and colored gemstones are where that guidance matters most. Blue is not one color: two sapphires at the same weight and price can look entirely different in daylight, and no photograph settles it.

So we would rather you saw several side by side under the same light, which is a thing a showroom can do and a screen cannot. Our consultants will pull a range and let you sit with it. Whatever you choose is covered by our lifetime warranty.

Frequently Asked Questions

What is the September birthstone?

Sapphire. It is most often recognized in a rich blue, and it makes a meaningful gift for anyone celebrating a September birthday. It is also the traditional gift for the fifth and forty-fifth wedding anniversaries.

How durable is sapphire jewelry?

Durable enough that the setting will usually need attention before the stone does. That is why sapphire turns up in rings far more often than softer colored stones, and why it is worth having the prongs checked periodically even though the sapphire itself is doing fine.

What colors do sapphires come in?

Blue is the familiar one, but sapphire occurs across a wide spectrum including pink, yellow, green and near-colorless. Montana sapphires in particular run to teal and green. If you love the stone but want something unexpected, ask to see the range.

How do I care for sapphire jewelry?

Warm water, mild soap and a soft brush keep it bright at home, and storing pieces separately prevents scratches to whatever is softer nearby. Bring it in for complimentary cleaning and inspection so we can check the setting at the same time.

Can sapphire be used in an engagement ring?

Absolutely, and it has a long history of exactly that. A sapphire center offers color and hardness at once. Our guide to blue sapphire engagement rings and wedding bands is the next stop if that is where you are headed.

Do you offer both natural and lab-created sapphires?

We do, and we will explain how each is formed rather than steering you. The practical difference is usually price at a given size, not appearance, and our consultants can put the two side by side so you can judge for yourself.

Can I create a custom sapphire piece?

Yes. Our in-house design studio and master jeweler can build a custom sapphire piece with you, whether you are starting fresh or reimagining a stone you already own. It is one of the more personal ways to mark a September birthday.

Do I need an appointment to shop for sapphire jewelry?

Walk-ins are always welcome, though booking gives you dedicated time with one of our experts, which matters with a stone this variable. Reserve a visit and we will have pieces pulled and waiting.
