How can I judge the value and quality of a gemstone?

Simply put, the type of gemstone and color you select should be the one you like the most, the one that will give you the most pleasure to wear. However, colored gemstones are judged by their beauty rarity.

The same “four C’s” that establish quality in Diamond are used for colored gemstones: cut, carat weight, clarity and most importantly, color.

Colour The more pure and vivid the color, the more valuable the gemstone.

Cut All gemstones must be cut well to attain their maximum potential for beauty. Quality cutting is what produces the brilliance and scintillation that captures the eye of the beholder.

Clarity Gemstones contain characteristic inclusions that provide proof of their natural origin. Those inclusions should not be so visible that they detract from the beauty of the gemstone.

Carat Weight Obviously, larger gemstones are more rare. However, some gemstones, such as Amethyst and Tourmaline. Routinely occur in very large sizes while others, such as Ruby and Sapphire, rarely occur in sizes above 2 to 3 carats in fine quality.

  What is the difference between precious and semi-
    precious gemstones?

The term “semi-precious” is somewhat misleading as it suggests that some gemstones have inferior value. Years ago, most people considered Ruby, Emerald and Sapphire as the “precious” gemstones and all others as “semi-precious.” In truth, all natural colored gemstone are rare and precious and their prices are determined by the availability and quality of the gemstone.

  What do I do if I fall in love with a gemstone, but I 
    don’t like the mounting?

Unless you have chosen a gemstone with a very unusual cut or one that is set in a custome-made ring, there is no reason you can’t have the gemstone you desire in a setting you prefer.

An experienced jeweler can offer you a variety of designs or custom settings that can accommodate the gemstone you have selected. Also many gemstones are cut to consistent dimensions, known as “calibrated” sizes. These gemstones fit into a variety of different settings. Ask your jeweler to help you select the perfect combination for you.

    and insured?

Ask your jeweler and your insurance agent for their recommendations.
