I really love the combo of these three stones!  Bold and confident. 
Diamond, in its rarity and beauty, is a symbol of love and strength of character, ethics, and faithfulness to oneself and others. It indicates the loving and open nature with which one came into the physical realm and encourages the aspect of truth and trust. 
Emerald opens and nurtures the heart. Its soothing energy provides healing, freshness and vitality to the spirit. A stone of inspiration and infinite patience, it embodies unity, compassion and unconditional love. 
Turquoise is a stone for self-forgiveness and self-acceptance. It encourages us to honor ourselves, bringing hope, discovery, and balance.
