Diamond information

When purchasing a diamond it is good to know the four "C's"


Christian Nevin began designing jewelry with just a few select stones. Now twenty years later. Christian Nevin Designs has built solid relationship with a few select gemstone dealers. If a spific gem is required for the piece , we will mostlikely be able to get it.

All of our larger diamonds have certification from GIA, EGL, HRD, or IGI, recognized and respected throughout the world. Through the years we have built a very good reputation for listening to our customers and meeting their needs. Getting the best stone for your money isn't always easy. We are careful not to compromise quality for cost. Cheaper is not always better when it comes to gemstones. Simply because it shows.






Cut   Carat   Clarity   Color  

Cut is considered by many to be the most important "C". Only when precisely calculated planes and angles are used, does the stone achieve its greatest possible beauty.

  The term carat is a measure of weight. The cut of a diamond can make it appear larger or smaller than its actual weight. As the weight of a diamond increases, so does its per carat cost. It is for this reason that a 1-carat diamond may cost 5 times more than a half-carat diamond.  

Clarity is a term used to describe the absence or presence of flaws (blemishes or inclusions) inside or on the surface of a diamond. Inclusions (inside the diamond) may include crystals, fractures, clouds, and cavities. Surface blemishes may include scratches, nicks, pits, abraded facet edges, extra facets and naturals.

  The GIA (Gemological Institute of America) has established an industry-accepted color grading system that rates diamonds with alphabetical letters. D (no color) is the most expensive "color" and N through Z (very light to light yellow), the least expensive. Diamonds that are graded from D through J are best suited for jewelry because they look colorless or nearly colorless.
