The 4 Cs Of Diamond Quality

The Third C: Color

The Fourth C: Clarity

What is a Certificate?

A certification is an independent quality report on a specific diamond. It is issued by a diamond grading laboratory with no affiliation to any retail outlet. This gives the customer a completely objective opinion on the diamond’s quality. The certification includes the exact measurements, proportions, color grade, clarity grade, cut grade and carat weight of the diamond. It also includes specifics that most jewelers do not have the equipment or the knowledge to determine, such as the diamond’s fluorescence, polish and symmetry. Each certificate is numbered, dated and illustrates the internal and external characteristics of a diamond.

As a direct diamond importer, we certify our diamonds with the leading diamond laboratories in the world:

  • GIA (The Gemological Institute of America): established in 1931 and is recognized as the world’s foremost authority in diamond grading.
  • IGI (International Gemological Institute):established in 1975, IGI is the world’s largest independent gem certification and appraisal institute for diamonds, colored gemstones and jewelry.

The primary difference between the above laboratories is their grading standards; in general, the GIA is stricter than the EGL and the IGI. There are also other labs that certify diamonds and their grading standards may vary.

How is a Certificate different from a jewelry appraisal?

At first, a certificate and an appraisal may seem like a similar document – however, they are vastly different.

An appraisal is a document created for the customer by a jewelry store. There are no industry established guidelines when creating an appraisal, and for that reason the appraisal is based solely on the professional opinion of the jeweler.

A certification, however, is regarded as the undisputed, independent quality report of the diamond that has been determined by a laboratory that does not benefit financially from the sale of the diamond.

At Sky Diamonds we offer both certified and non-certified diamonds – all provided to you with a complimentary appraisal for your records and insurance purposes.

LAB Created Diamonds (Lab Grown)

In lieu of diamonds mined out of massive holes in the earth, SKYLINE proudly offers diamonds that are sustainably cultured by recreating the extreme pressure and temperature required to convert carbon into a diamond’s crystalstructure.Today the proprietary process for growing diamonds is one of the mostprecise and difficult manufacturing techniques that humans have ever achieved.So, the question is now, “are lab-created diamonds, real diamonds?” Theanswer is a very simple, yes.The only thing that makes a lab-created diamond different from a naturaldiamond is its origin. A lab-created diamond is grown inside a lab usingcutting-edge technology that replicates the natural diamond growing process.The result is a man-made diamond that is chemically, physically, and opticallythe same as those grown beneath the Earth’s surface.The diamond grading process is roughly the same for all of the diamondcertification labs. Each diamond is graded independently by several gemologistsat the lab and the individual grades are then compiled and analyzed todetermine the final grade.
