A Gift Of Meaning

When I am older and I make my own money, I want to buy my mom a meaningful necklace that she will love. I want the necklace to have a diamond heart on it to show how much I love and care for her. She raised me for so long and I need to repay her with something she could keep for a long time. I also want this necklace to pass down onto the family to even have more meaning to it. I want the color of the necklace to either be red, black, or purple. :)
