The Magic of Phenomenal Stones
There’s something about June in the Pacific Northwest that feels almost dreamlike.
The rivers run fuller from the mountain snowmelt. Evening light lingers a little longer. Water reflects the sky in shifting colors that never quite look the same twice. It’s a season of movement, glow, and quiet transformation.
Some gemstones capture that same feeling.
Known as phenomenal gems, these rare stones interact with light in extraordinary ways. Rather than showing a single static color, they shimmer, shift, glow, or reveal hidden effects as they move. They feel alive in the hand — changing with sunlight, candlelight, or even the angle from which they’re viewed.
Perhaps the most famous is alexandrite, one of June’s birthstones. Long prized for its rarity, alexandrite is known for its remarkable color change. In daylight, it may appear green or teal-blue; under warmer evening light, it can shift dramatically toward raspberry, plum, or red. It’s a gem that seems to hold two personalities at once — like river water changing color beneath the sky.
Moonstone offers a softer kind of phenomenon. Its floating inner glow, known as adularescence, drifts across the surface like moonlight on moving water. Pearls, another of June’s traditional gems, possess their own quiet magic as layers of nacre reflect light with a soft, luminous depth.
But the world of phenomenal gems extends far beyond June’s birthstones. Some sapphires reveal stars that glide across their surface. Certain opals flash with shifting spectral color. Cat’s eye chrysoberyl creates a narrow band of light that opens and closes as the gem moves.
Labradorite flickers with electric blues and greens reminiscent of sunlight dancing across a forest stream.
These optical effects are not enhancements or tricks. They are natural phenomena created deep within the earth through microscopic structures, inclusions, and the way light interacts with the gem itself. No two are ever exactly alike.
That individuality is part of what makes phenomenal gems so captivating.
At Olufson Designs, we’re celebrating these extraordinary stones throughout June with river-inspired displays featuring alexandrite, moonstone, pearls, and other gems that play with light in unexpected ways. Alongside them, you’ll also find pieces from TOBY POMEROY, whose designs often echo the natural movement and textures found in the Pacific Northwest landscape.
Some gems sparkle.
Others seem to breathe with light.
And once you’ve seen a phenomenal gemstone in person, it’s hard to forget the experience.
