Genuine Diamond

Diamond forms under high temperature and pressure conditions that exist only about 100 miles beneath the earth’s surface.

Diamond Buying Tips

Diamond Weight & Size

Some people want to buy the biggest diamond possible. Is this always the right choice? We feel that it's always a matter of preference, but here's something to think about:

The larger the diamond, chances are the more characeristics it likely has, and because it's larger, these characeristics are typically even more visible than on a smaller diamond. But most importantly, if the diamond cut isn't proportioned correctly, it won't return the maximum amount of light through the top of the diamond.

This illustrates that no matter how large the diamond, its cut and proportions determine how brilliant the diamond really is.

Diamond Color

Since diamond colors range from colorless to yellowish-brown, sometimes these colors can add warmth or depth to your diamond. Also, by mounting a non-colorless diamond in yellow gold can make the diamond appear colorless in some cases.

4 C's of Diamonds

  • CLARITY - Clarity grades assess the number, size, relief, and position of inclusions and blemishes.
  • COLOR - The less color, the higher the grade. Even the slightest hint can make a dramatic difference in value.
  • CUT - Cut (proportions, symmetry, and polish) is a measure of how a diamond’s facets interact with light.
  • CARAT WEIGHTRarity means larger diamonds of the same quality are worth more per carat.

Gemstone Buying Tips

Choose Wisely

Buying a gemstone is often a very different experience than buying a diamond. Gemstones are selected based on favorite colors, wardrobe matches, personality, and fashion trends. While gemstones are judged using the 4Cs, just as diamonds do, each is judged separately. For example, a sapphire is compared to another sapphire, but wouldn't be compared to an emerald or aquamarine. Choose your gemstone jewelry based on your personal preferences.
