Natural Gemstones

Gemstones allow you to bring a lot of color to your jewelry. From the deep purple of amethyst to the delicate pink sapphire to the gentle butter-yellow tourmaline, gemstone jewelry allows you to show off your personality. Remember that gemstones too have different grades of quality, and it is important to educate yourself about the qualities that are assessed to determine the overall value of your chosen stone.

Blue Sapphires

Blue sapphires are blue color gemstones, and are a variety of the mineral corundum, an aluminium oxide. (Rubies are also a variety of the mineral corundum.)

Pink Sapphires

Pink Sapphires

Pink sapphires are significantly rarer than blue and yellow sapphires. In many ways, pink sapphires are more similar to rubies than sapphires of other colors. Gemologists often have difficulty differentiating between rubies and pink sapphires. (After all, Pink is really just light red!) Pink sapphires connote femininity and delicacy.

Gemstone Clarity

Gemstone Clarity

In natural gemstones, clarity refers to the amount of internal flaws (inclusions) or external flaws of each stone. Most gemstones have inclusions, and finding a flawless gemstone is rarer than finding a flawless diamond. The process within the earth that occurs when gemstones are formed is what determines their number of flaws.

Gemstone Grading

Gemstone Grading

The grading system used on precious gemstones is just like that of diamonds, but also considers the following: transparency, which transmits light without serious diffusion; translucence, which allows light to pass through, but only diffusely (semi-transparent); and opacity, which does not allow light to pass through.

Gemstone Cut

Gemstone Cut

A natural gemstone can be cut the same way that any diamond can, although each stone has particular features that lend themselves to particular cuts. Brilliant cuts are made to maximize the amount of light return from a gemstone by being cut with many facets.

Gemstone Polish

Gemstone Polish

Darker-colored and opaque gemstones can be polished instead of faceted. This is called the cabochon cut, which consists of a smooth, rounded surface with no facets for the light to dance off of. It does, however, create the "cat's eye" and "star" effects, which are equally beautifully in their own way.
