These 10k gold and sterling silver Celtic Knot drop earrings feature intricate knotwork which consists of four simple Celtic knots enclosed in a circle accented by an emerald in the centre. One of the knots is finished in 10k yellow gold which adds a unique dynamic to the design of the earrings. The Celtic Knot was created on the pages of illuminated manuscripts. From dawn till dusk, monks would work with infinite care to illustrate the gospels.. This patience and devotion produced the richly decorated knot work which today is instantly recognizable as Irish. A timeless gift from Ireland.
