It was my great grandmother''s. It is an old mine cut (will have it appraised in February) 18K white gold...but it doesn''t affect my skin, so I don''t know how it could have nickel in it. I believe she bought it between 1920 to 1925 because white gold wasn''t made much before 1920 and mine cuts pretty much stopped after ''25. What I''d really like to know is the company. It says G*M*Co 18K on the inside. The funny thing was I rested my head on my hand tonight and realized I could watch the tv perfectly in my diamond, LOL.
