The story of my friend

As a young historian, I can say people wear necklaces for thousands of years. We can find necklaces throughout whole history. However, I never thought a necklace can change my life.
It was 5 years ago, I had got the first chance in my career to give speech in an international conference. I took the trip with Kathy, a pretty girl, one of my teammates. The speech was so successful that I was keeping exciting . On the last day, when we were on the way to the airport, I still talked about my speech.
Finally, Kathy said: “Oh, my boy, of course it is my pleasures to be your teammate and share your success, however, listen to me carefully, after three days of listening your brilliant speech, formal or informal, please do me a favor, OK?”
“What? I am sorry, I can shut up.”
“No, No, I understand, a shy boy finally can talk in front people, I know it. Now the only thing you need to do is to company me to go somewhere, you know, I had never been here. And you can keep talking and I can do something girls like. We still have 3 hours.”
I did not know why I always enjoy any attitudes from Kathy. Moreover, I realized it was the first time we are together in a strange city, just two of us. I smiled and agreed: ”OK, let us go somewhere.” During the three hours, we randomly walked and walked through the city. At the last moment, we entered a jewelry shop.
“Wow, look this, how it is beautiful! Let me try it” Kathy pointed a necklace to me.
It was a sky blue CZ necklace, begins with a chain made from marquis cut CZs, linked together with tiny silver loops. These CZs meet front and center, at an impressive 16 carat, oval cut, sky blue CZ. The center stone is bordered by a medley of clear marquis, pear, and cushion cut stones that complete Emitations' replica CZ Hope Diamond Necklace.
“How do you think?” Kathy wore the necklace, turned around and asked me.
At the moment, suddenly, I had forgot how to pronounce other words: “You are beautiful.”
“Am I? Or I am beautiful because of the necklace?”
“You are beautiful, always, with or without the necklace. But let me buy it as my gift for you.”
“Why, I can afford it.”
“Because I… ”
since the moment, my life has been changed। We spent extra 30 minutes at the shop and had missed our flight. Fortunately, we have not missed each other.
