Forget basic orange and brown. October’s real color story is midnight black, merlot, cognac, forest green, plum, fire and honey—and there’s a gemstone for every one.
October may have two official birthstones—opal and tourmaline—but why should they get all the fun? Look outside. This is the month when nature basically dumps out the entire jewelry box. Leaves turn garnet red, afternoon light goes honey-gold, forests deepen to green and evenings arrive dressed in black.
So we’re creating our own Fall Gem Palette, inspired by the colors and moods of October. And yes, black diamonds made the cut. Obviously.
MIDNIGHT — Black Diamond | Mystery & Strength
October gets deliciously darker, and black diamonds are ready for it. Their dramatic color gives traditional diamonds an unexpected edge, while their durability makes strength an especially fitting theme. Midnight is for embracing the season’s mysterious side—and perhaps becoming just a tiny bit more mysterious ourselves.
MERLOT — Garnet | Passion & Warmth
Deep, rich and almost wine-colored, garnet looks like October poured into a gemstone. Long associated with love, passion and protection, it’s our reminder to pull the people and things we love a little closer as the temperatures drop.
COGNAC — Smoky Quartz | Grounding & Letting Go
Smoky quartz ranges from translucent brown to nearly black and has long been associated with grounding. For October, we’re giving it another job: letting go. The trees seem pretty good at it, after all. Maybe there’s something to that.
FOREST — Green Tourmaline | Growth & Renewal
Tourmaline is one of October’s official birthstones, although pink often gets the attention. We’re heading into the woods with green tourmaline instead. Associated with vitality and growth, it reminds us that autumn isn’t simply an ending. Nature is already preparing for what comes next.
PLUM — Amethyst | Calm & Reflection
Those deep purple tones belong beside October’s burgundies and forest greens. Amethyst has been associated with calm and clear thinking for centuries, making Plum our cue to slow down as the days grow shorter. Permission granted.
FIRE — Fire Opal | Creativity & Transformation
Now this is October. Fire opal can glow with yellow, orange and red, mirroring the leaves outside—and opal happens to be October’s other official birthstone. Fire represents creativity, spontaneity and transformation. In other words: change doesn’t have to arrive quietly.
HONEY — Citrine | Joy & Abundance
Golden citrine brings us straight to harvest season. Traditionally associated with warmth, happiness and abundance, Honey is about noticing what we’ve gathered this year instead of immediately chasing what’s next.
Did You Know?
Black diamonds get their mysterious color from dense concentrations of dark inclusions within the stone, while October’s official gems—opal and tourmaline—are among the most colorful gemstones on Earth. Put them together with garnet, smoky quartz, amethyst and citrine, and October suddenly has a much bigger jewelry box.
A Little History
Gemstones have carried symbolic meanings for thousands of years, with different cultures connecting them to everything from protection and courage to love, prosperity and clarity. The modern standardized birthstone list arrived much later, in 1912, but our Fall Gem Palette borrows from those older traditions to tell October’s story through color.
