If you hadn't considered an opal engagement ring already, let us introduce you to their mystifying beauty and allure. "For the untraditional non-diamond bride, opals make the perfect engagement ring because they display a different kind of sparkle than a diamond—a magical, iridescent sparkle," explains jewelry designer Misa Hamamoto. "You can't deny the wondrous beauty within an opal and each opal is truly one-of-a-kind which is fitting for the one-of-a-kind bride."
What Is an Opal?
An opal is an incredibly unique gemstone known for its display of flashing colors, which is called play-of-color. Formed during the dry period after seasonal rains in regions like Australia, the opal is also the October birthstone.
She continues, "The wonderful thing about opal jewelry is not only that they're absolutely stunning, but they are much more budget friendly than big diamond rings."
Meet the Expert
Misa Hamamoto is a jewelry designer and creator of Los Angeles-based Misa Jewelry.
If you're looking for deep meaning with your engagement ring stone, look no further. Known as "The Queen of Gems," and recognized as the October birthstone, opals have incredible significance attached to them, dating back to the middle ages—it was believed opals had the power to make their wearer invisible. Opals rose back into fashion when Queen Victoria became fascinated with them. Other famous opal-lovers in history include Cleopatra and Empress Josephine. So you're in good company. In fact, it's so difficult to resist the charms of these stones that we're willing to bet you've already fallen under their spell, so here are some facts before you begin the search for your perfect ring.
- Opals come in a wide variety of colors and are characterized by their background tone. White is the most common color and black opals are the most expensive.
- The ethereal flashes within the stone are called its "play of color" and can occur in a kaleidoscope of hues.
- There are opals with very muted plays of color that can seem completely opaque.
- Opals, like pearls, are smooth stones and not faceted like other gems.
- Opals are one of the softest gemstones and need to be handled gently. Lab-created opals tend to be a bit stronger than their natural counterparts.
"We advise that you wear your opal jewelry with great care and love so they become future heirlooms," says Hamamoto. "Don't submerge them under water, don't apply harsh cleaning agents to them, and don't go rock climbing with them! (One of our clients did this and they learned the hard way)."
