Rings that display Celtic knot work are becoming ever more popular choices for wedding bands. As it has no beginning or end, the round shape of the wedding or engagement ring is a sign of never-ending love and fidelity. The continuous strand of the Celtic knot is also a sign of perpetuity and is a striking complement to the symbolism of the ring itself. The crossing of the strands of the knot stands for how our lives are intertwined.

Spirals, Triskeles, and Triquetas, Shield Knots and Sun Symbols are all types of Irish wedding rings. However, most popular by far is the Irish Claddagh. Different traditions give different meanings to the Claddagh, depending on how it is worn. The tale of the Claddagh starts when buccaneers captured a fisherman Richard Joyce and other crewmembers shortly before Joyce was to be married. They sold Joyce to an Algerian goldsmith, and it was there that Joyce made the first Claddagh, named for the village where his fianc'e still waited for him.

Two German mineralogists discovered the cubic form of zirconium oxide in 1937, but it wasn't until the 1970s that Soviet scientists learned how to grow this mineral in the laboratory. It was then that jewelry designers first took notice of Cubic Zirconia.

Even trained gemologists find it difficult to tell the difference between Cubic Zirconia and real diamonds with the naked eye.

Any ring that can be made with near-colorless diamonds can also be made with yellow diamonds.
