This is a 14kt white gold L shape Nose ring with a size 1.7mm Diamond. The Nose ring is a 20 Guage. Thia is a diamond, It's not cubic zirconia.  The card for authenticity is included. I opened and saw that the Guage size is too small for me. I sanitized it since I opened the plastic but item is new.  Bought from Lavari Jewlers. Ships fast.
