This 18K White Gold Aquamarine & Diamond Ring in size 5.5 is a stunning piece of fine jewelry. The oval-shaped natural Aquamarine shimmers with a beautiful blue color. It is rich in color and saturated with the sparkling color of tropical waters. The aquamarine is approximately 1.6 carats. It is accented by 6 sparkling diamonds, totaling approximately 0.06 carats. The ring is stamped with a maker’s mark and 18K, but is hard to see as is under the ring adjuster. It would be sizable and the adjuster could be removed by a jeweler, if needed. If you have larger knuckles and have searched for a way to tighten it after it slides past your knuckle, this ring is already setup to do that for you. 
The solitaire with diamonds accents styling is classic and timeless and can be dressed up or down, depending on the occasion. The beautiful blue color goes with so many things. The stone is just very slightly loose, but the prongs are in good condition and can be tightened down. Overall, this gorgeous ring is in good, used condition.
