Opal Birthstone: October’s Stone of Color

Opal is October's traditional birthstone. Why it makes a wonderful, one-of-a-kind birthday gift, how to choose one, and how to care for it.

Of all the birthstones, opal is the one I would have chosen for myself, and as it happens it belongs to October. It is the only common birthstone that holds every color at once, which makes it a wonderful gift for an October birthday. After fifty years working with it, here is what makes opal such a special birthstone and how to choose one.

Opal is October’s birthstone

Opal is the traditional birthstone for October, sharing the month with tourmaline. For the full picture of the month and how the two stones compare, see my guide to the October birthstone. But opal is the classic, and for most people it is the one that comes to mind first.

Why opal makes a wonderful birthstone

The reason is the fire. Opal shows a shifting rainbow of color called play-of-color, and because every stone is unique, an opal birthstone is genuinely one of a kind. No one else has quite the same stone. It also carries a warm old reputation, long associated with hope, creativity and loyalty, which makes it a thoughtful gift rather than just a pretty one.

Choosing an opal birthstone

The lovely thing is the range. There is a body tone and a budget for everyone, from bright affordable white opal to dramatic black opal at the top of the tree. If you are buying for someone who will wear it daily, I often suggest Australian or boulder opal for their toughness. For the full rundown of the choices, see my guide to the types of opal, and for what drives the price, how much is opal worth.

Is opal a good everyday birthstone?

It can be, with a little care. Opal is softer than a sapphire or a diamond, around 5.5 to 6.5 on the Mohs scale, so a ring deserves gentle handling and the odd rest from rough work. None of that should put you off; it just means treating it kindly. I set out the simple routine in caring for opal jewelry. And if anyone repeats the old line that opal is unlucky, the truth is in opal meaning: it is a myth from a novel, nothing more.

An anniversary stone too

Opal is also the traditional gift for a fourteenth wedding anniversary, so it works for more than just October birthdays.
