I've always loved the color of blue sapphires. Blue sapphires and diamonds even better!
On another note, turquoise is another favorite of mine!
I love both my diamond wedding rings. For our silver anniversary, my husband had my grandmother's diamond reset for me. The beauty is in the love and meaning!
One of my favorites is Tanzanite. I have a beauty set in a ring for myself.
Sapphire, Diamonds, and Ruby.
Star sapphire! It's gorgeous.
