What Makes a Good Diamond? The 4C's




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



Diamonds are valued by their lack of Color. With the exception of colored diamonds like yellow, pink, and blue diamonds, the less color the more expensive the diamond.

Since carats are a measure of weight, it doesn’t necessarily reflect the dimensions of a diamond, making it extremely important that you see a diamond in person to experience its unique shape and beauty. Not two diamonds are ever the same! 



 Diamond Clarity refers to the amount of inclusions and blemishes on a diamond. It’s extremely rare to find a diamond without any markings, making those inclusion and blemish free diamonds the most valuable of all. 



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

See For Yourself!

Malka Diamonds is located in downtown Portland on SW 3rd Avenue. We're Open from 9AM - 5PM Monday through Friday and 10AM - 4PM on Saturdays.

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.


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


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

Frequently Asked Questions


I’ve never bought a diamond before and I don’t know what I’m doing. Can you help?

We believe that buying a diamond engagement ring should be a fun experience both you and your partner look back on fondly. You should not have to worry and stress! At Malka Diamonds, we think education is everything. We’ll teach you everything you need to know so you and your partner can purchase the perfect diamond ring in confidence.

What is a GIA certified gemologist?

The Gemological Institute of America (or GIA) is a nonprofit institute focused on gemology education and research. A GIA certified gemologist is a professional gemologist that has gone through an extensive full-time study and hands-on training. It is the highest certification available for the profession. 

Here at Malka Diamonds, we have 2 GIA certified gemologists on staff. Given many jewelers here in Portland have none, we are proud to have them available to answer any diamond questions you may have.

When I buy an engagement ring, do you recommend an appraisal?

Yes! Not only do we recommend it (you’ll need one for insurance purposes), but a free appraisal is always included with your engagement ring purchase. As certified GIA gemologists, we’re happy to offer this service at no added cost. In fact, we don’t believe in hidden costs or extra charges – ever.
