Full Moon & New Moon: Settle, Reflect, & Manifest

Celestial Key Dates

• Full Moon — 4 December 2025 (13° 03′ Gemini). 

• New Moon — 19 December 2025 (28° 24′ Sagittarius). 

These two powerful lunations frame the close of the year — the Full Moon in Gemini emphasizes clarity, communication, and releasing mental clutter; the New Moon in Sagittarius invites fresh vision, big-picture intention and expansion.

What This Means for You

➡ Full Moon in Gemini (4 Dec)

Gemini energy is about the mind, networks, adaptability and storytelling. At this Full Moon, you’re encouraged to release overthinking, mental noise and patterns of distraction — making space for clarity and fresh communication. Use this time to review your year, refine your voice, complete unfinished mental loops, and prepare to step into new vision.

➡ New Moon in Sagittarius (19 Dec)

Sagittarius is the sign of exploration, truth-seeking, faith, and wider horizons. This New Moon is a potent moment to plant seeds for your next chapter — big ideas, travel, learning, freedom, belief and alignment with purpose. As one year ends and another nears, lean into what you truly want to trust, expand into and carry forward.

Crystals to Match the December Cycle

To align with this lunar theme and the twin focus of clarity + expansion, consider introducing crystals that amplify communication, energy flow and vision:

• Clear Quartz — a master amplifier of energy, perfect for clearing mental clutter and preparing for new intention. (See our Clear Quartz Collection)
  

• Blue Lace Agate or other blue crystals — support clear speaking, calming an overactive mind, aligning with Gemini’s communicative tone. (Via Blue Crystals)
  
  

• Amethyst — great for bridging mind + intuition, helping transition from reflection (Full Moon) to visionary clarity (New Moon). (Visit Amethyst Collection)
  
  

• Citrine or other yellow-gold crystals — align with Sagittarius’ expansive, optimistic energy and manifestation vibration. (Explore Citrine Collection)
  
  

• Green Aventurine — for growth, forward-motion, abundance — helping you step into the next cycle with confidence. (See Green Crystals)
  
  

How to Work with This Energy

1. Full Moon Ritual (4 Dec)

• Write down what thoughts, patterns or stories you’re ready to release.

• Hold a Clear Quartz or Amethyst over your head (or third-eye) and visualize the mental fog clearing.

• Speak your truth: say out loud what you’re done carrying.

• Cleanse your space + crystals to reset energy for the next cycle.
  
  

2. Between the Moons (5-19 Dec)

3. New Moon Ritual (19 Dec)

• Choose 1-3 intentions aligned with growth, truth and freedom.
