She expanded that knowledge to jewelry and gemstones as her love for making jewelry grew. Her knowledge and willingness to teach and help others were unmatched. She would spend many summers in her garden, enjoying the springtime when she could watch the fruits of her labor grow. She had many joys in her life, family, friends, gardening, a great student of history and lover of all knowledge. Her many friends in and outside of the business loved her as much as we did. Her love and joy for life will sustain those left behind. She will be greatly missed.
