JEWELRY KEEPS MEMORIES ALIVE

MY LIFE PARTNER

''When I look at my diamonds, I am reminded of my partner. He gave me all my diamond jewelry, big and small. He is my life partner. My friend. My lover. He is the father of our children. He loves me and I’m reminded of that every time I look at my diamond jewelry.''

YOU DID IT!

''My most favorite piece of jewelry is a ring I had personally made for my 5-year work anniversary. When I look at it, I am reminded of all that I have accomplished in those 5 years. It feels like an extra push for me. Sort of: Look what you have on your finger, you did it yourself!''

CHEERS TO MEMORIES

''My favorite jewelry are these two golden rings, I always wear them and even with showering or sleeping I still have them on. I got them for my 21st birthday from my friends and parents, so they mean a lot to me. These rings remind me of the dinner party I organized for my 21st birthday and all the lovely people who attended.''
