When selecting a gemstone of color it is wise to choose with care as well as desire. Certain stones speak to us more than others. If you are a little rough on your jewelry and want to introduce color into your gem collection a sapphire or ruby is a wise choice. They are a nine on the hardness scale with only a diamond above at a ten. Ruby or sapphire can really take a lot of wear and not scratch or chip as easily as other colored stones will. So do be thoughtful when adding color to your jewelry wardrobe. Colored gemstones are a wonderful choice for engagement rings as well as fashion jewelry.
