GIA Certified

At Malka Diamonds in Portland, OR, we know all great rings start in the same place: a carefully chosen diamond. A beautiful diamond lasts a lifetime and symbolizes the love and commitment you and your partner share.


We know diamonds inside and out. When you visit our store (even if you’re just browsing), we want you to leave feeling like a diamond expert. Our GIA certified gemologists are committed to helping you understand your options when buying the diamond engagement ring of your dreams.

GIA Gradings System

The Gemological Institute of America (or GIA) is a nonprofit institute focused on gemology education and research. The institute has a number of easy-to-understand grading systems to assist in properly rating and grading diamonds.

GIA Gradings System


Carats measure the weight of a diamond. All else being equal, the higher the carat weight, the more valuable the diamond.

Color Scale

Much like the The GIA International Diamond Grading System, the GIA Color Scale aims to make understanding a diamond's colorlessness easy so you can make an informed purchase.

Starting with absolute colorlessness, the scale runs from D-Z and includes 5 tiers.

  • Colorlessness - D-F
  • Near Colorless - G-J
  • Faint - K-M
  • Very Light - N-R
  • Light - S-Z

Clarity Scale

The GIA International Diamond Grading System aims to make diamond grading more transparent and understandable. The scale ranges from flawless (FL) to diamonds with obvious inclusions (13), and is done by a skilled grader using 10x magnification.

The complete scale:

  • Flawless (FL) – No visible inclusions or blemishes
  • Internally Flawless (IF) – Some blemishes with no visible inclusions
  • Very, Very Slightly Included (VVS1 and VVS2) – Some very difficult to see inclusions are present
  • Very Slightly Included (VS1 and VS2) – Inclusions are clearly visible, but are characterized as minor
  • Slightly Included (SI1 and SI2) – Inclusions are noticeable
  • Included (I1, I2 and I3) – Inclusions are obvious, potentially affecting transparency and brilliance

Though most people find it hard to quantify, the Cut of a diamond has three attributes:

  • Brilliance- The light the diamond reflects
  • Scintillations - A diamond's sparkle
  • Fire - How light travels through a diamond
