We propose that it may be a blessing in disguise. Crystals can take energy and transmute it for us so when a crystal breaks we like to say it is a gift because it means that stuck energy has moved. We often think of this as the crystal 'taking the hit' for us. If the energy moved through your crystal, that is better than in some other way like through physical injury for example.The best thing you can do with a broken crystal is to give it back to the earth. Feel out a place that is resonant to you and your home, place an intention and ask the earth to accept this offering. You can bury the crystal somewhere special or simply place it in your garden. The gems love to go back to the earth.
