When shopping for a diamond engagement ring, you should:
Work with a reputable jeweler, like Schwanke-Kasten, who carries GIA certified diamonds
Know your budget. This typically depends on what your partner's expectations are, as well as what you are comfortable spending.
Be familiar with the 4C's when selecting a diamond. Established by the DeBeers Diamond Group, the 4C's are standardized parameters used to compare the characteristics of GIA certified diamonds. Specifically they are:
Cut - Clarity - Color - Carat Weight
The CUT of a diamond has two aspects. One is the actual shape of the stone – round, princess, oval, square, marquise, pear, emerald, cushion, etc. More importantly, the cut refers to the angles and dimensions used to create brilliance, fire and scintillation of a diamond as explained below:
The CLARITY scale measures a diamond’s purity or how free it is from tiny blemishes and inclusions. Blemishes are found on the surface like scratches and nicks. Inclusions are naturally occurring features that are in the diamond itself. They may appear as tiny fissures or feathers, crystals or other minerals. Diamonds equal in weight, color and cut will vary greatly in price depending on their clarity features. At Schwanke-Kasten Jewelers, the diamonds we use are SI or better.
The COLOR of a diamond actually refers to it's whiteness and is graded on a scale from D to Z, exceptionally white to tinted color as shown in the scale below. At Schwanke-Kasten, the accent diamonds in most engagement ring mountings are F-H in color.
The CARAT weight is just that; how much it weighs. A diamond with a different cut can have the same weight, but can also appear different in size. One carat (1 ct) equals 0.20 grams and is divided into 100 points. So a half carat - 0.50 ct - diamond can be described as a 50 point diamond. It's important to remember that a diamond is not valued by carat weight alone and two diamonds of equal carat weight can have very different values depending on cut, clarity and color.
When purchasing a loose diamond for a mounting, you should:
Carefully place the diamond on the top of your hand and compare it with a similar diamond mounted in jewelry.
Hold it up to the light and look at how the light dances around – it should throw out a rainbow and display the diamond’s natural brilliance.
Look at diamonds of different clarity, shapes and sizes to find the one that is perfect for you. Remember, in some diamonds, the internal features may be hidden by the mounting and will not detract from a diamond’s overall beauty.
At Schwanke-Kasten Jewelers every center stone diamond selected is:
Certified by GIA® (Gemology Institute of America), the world's most recognized diamond grading laboratory created by DeBeers;
Exquisitely cut and individually checked so it can be perfectly mounted into your chosen setting;

Additionally, any accent diamonds used in our ring mountings will be F-H in color and VS2 in clarity, or better.
