When I went to the jewelry store, I couldn''t believe how wonderful my ring looked. It''s an older cut ring and the appraiser said it''s modern day counterpart would be a cut grade of good. At home, it don''t sparkle a lot. I love it anyway because my grandmother gave it to me with love. Anyway, I couldn''t believe how much it sparkled in the store, especially the fire that was bouncing off of it. I think I read that they use halogen lights, right? If that''s the case, I want to get some for my home.
