I ordered the Pi symbol necklace in gold for my best friend. She is returning to upgrading her math and science skills in her mid 30s and I will never forget her terror the day before she started. But now she's winning an award for maintaining an A average over the past two years, all while working full time. I'm so proud. I wanted to get something for the award ceremony to mark the occasion and this necklace is perfect. The shipping was lightning fast and the necklace is beautiful. The gift box is worth it. Thank you so much, I know I will be a repeat customer.
