The Moon, the Feminine and the Crystals – December 2025

The Moon, the Feminine and the Crystals
December 2025

December brings a deep and beautiful stillness. The nights are at their longest, and the world outside grows quiet. This month offers us a chance to pause. The Moon glows with a steady light, teaching us that rest is not a stop but a necessary root for future growth.

The Moon’s journey this month includes nine phases, guiding us through the final release of the year and into the fresh promise of the Winter Solstice.

December’s Full Moon is known as the Cold Moon. It rises high and bright in the sign of Gemini, reminding us that even in the depth of winter, there is light to be found if we look within.

I have selected crystals to pair with each phase. These stones support the specific zodiac energy of the Moon and the theme of gentle stillness.


The Nine Phases in December

Full Moon in Gemini – 4 December (Cold Moon) The Cold Moon rises with brilliance in the sign of the Twins. Gemini energy is about communication, truth, and mental clarity. This is a moment to speak your truth and clear any mental fog before the year ends. Crystals: Clear Quartz for mental clarity, Selenite for cleansing busy thoughts, Moonstone for emotional balance.
Waning Gibbous – 5 to 10 December As the light softens, we move into gratitude. The intensity of the Gemini Full Moon fades, leaving space for reflection. Look back at the year with a gentle gaze. Crystals: Green Aventurine for gratitude, Smoky Quartz for grounding energy.
Last Quarter in Virgo – 11 December The Moon is half lit and fading in the sign of Virgo. Virgo loves order and detail. This phase brings a necessary release and is the perfect time to organise your physical space and clear emotional clutter. Crystals: Black Tourmaline for protection, Amethyst for calming the analytical mind.
Waning Crescent – 12 to 18 December The final sliver of light before the darkness. This phase holds space for deep rest. Your energy may feel lower, and that is natural. Listen to your body and move slowly. Crystals: Lepidolite for peace, Howlite for calming the mind.
Dark Moon – 19 December Complete stillness. The sky is dark. This is the void where all potential resides. Rest here. There is nothing you need to do but simply be. Crystals: Labradorite for trusting the unknown, Obsidian for deep grounding.
New Moon in Sagittarius – 20 December A new cycle begins just before the Solstice. The New Moon arrives in the adventurous fire sign of Sagittarius. In the darkness, the first seed of hope and vision is planted. Dream big for the year ahead. Crystals: Citrine for abundance and expansion, Carnelian for motivation.
Waxing Crescent – 21 to 26 December A faint light returns, coinciding with the Winter Solstice. Hope begins to stir. Take the first small steps toward the intentions you set during the New Moon. Crystals: Clear Quartz to amplify your vision, Red Jasper for steady progress.
First Quarter in Aries – 27 December Half the Moon is visible in the fiery sign of Aries. As we approach the New Year, this phase encourages bold decision and focus. Realign your compass and commit to your path with courage. Crystals: Fluorite for focus, Tiger’s Eye for confidence and action.
Waxing Gibbous – 28 to 31 December Momentum builds as we cross into the next year. The energy is expectant and bright. Trust the process and carry your light forward with confidence. Crystals: Sunstone for vitality, Clear Quartz for directing energy.

Planetary Movements and Energy Themes

December carries significant energy marked by the turning of the solar year.

Mercury in Sagittarius

Mercury is moving forward through Sagittarius this month. This brings a sense of optimism to our communication. After a period of reflection in November, you may find it easier to articulate your big picture dreams for the future.

The Winter Solstice (21 December)

This is the pivotal moment of the month as the Sun enters Capricorn. It is the longest night and the turning point where the light begins to return. It is a celebration of rebirth and hope.

Venus enters Capricorn

On 24 December, Venus moves into earthy Capricorn. This shifts our focus toward long term commitment and stability. It reminds us that love and connection are built on strong foundations.

The Divine Feminine

December holds the energy of the Wise Woman. She is the aspect of the Divine Feminine who is comfortable in the dark and knows that winter is a resting place, not an end. The Moon mirrors this wisdom, showing us that we do not need to shine brightly all the time to be whole.

Crystals act as lanterns during this season. Selenite connects us to the white light of the winter sky, while Black Tourmaline keeps our feet firmly planted on the earth. When used together, they create a circle of safety, allowing us to rest deeply.

Rituals and Reflections

Full Moon in Gemini (4 Dec)

Create a quiet space. Light a white candle and write down the thoughts or stories that no longer serve you. Burn the paper safely to release them to the air.

Winter Solstice (21 Dec)

Wake before dawn if you can. Light a candle or hold a piece of Citrine to welcome the sunrise. Speak a word of welcome to the returning light.

New Moon in Sagittarius (20 Dec)

Write a letter to your future self for the coming year. Focus on adventure and growth. Place it under a Clear Quartz crystal overnight to charge it with intention.

Closing Thoughts

December is a threshold. The Cold Moon and the Solstice work together to guide us from the old year into the new. It is a time to move slowly and with care.

The phases of the Moon this month invite you to shed your old skin and prepare for rebirth. The darkness is not something to fear. It is the fertile soil where your new dreams are waiting to sprout.

Work with your crystals, listen to your intuition, and trust the timing of your life. Rest well, breathe deeply, and know that the light always returns.
