Diamond Guide

When shopping for Diamonds, two essential factors to consider are colour and clarity. These aspects greatly influence a Diamond's appearance, quality, and value. This guide will help you understand the significance of Diamond colour and clarity.



Diamond Colour

Diamond colour refers to the presence or absence of colour in a diamond. The Gemmological Institute of America (GIA) grades diamond colour on a scale from D (colourless) to Z (light yellow or brown). Here's what you need to know about diamond colour:

D-F: Colourless

  • Diamonds in this range are extremely rare and highly valuable.
  • They appear icy white, allowing maximum brilliance and fire.

G-J: Near Colourless

  • These Diamonds offer excellent value for those seeking nearly colourless gems.
  • Often indistinguishable from D-F Diamonds when mounted in Jewellery.

K-M: Faint Yellow or Brown

  • Diamonds in this range may exhibit a noticeable hint of yellow or brown.
  • Their value is lower than near colourless Diamonds but can still be attractive.

N-Z: Light Yellow or Brown

  • These Diamonds have more pronounced colour and are typically less desirable.
  • They are less expensive but may not exhibit the same sparkle as higher-grade Diamonds.



Diamond Clarity

Diamond clarity refers to the presence of internal and external imperfections, known as inclusions and blemishes, respectively. The GIA grades diamond clarity on the following scale:

Flawless (F)

  • These Diamonds are exceptionally rare and have no visible inclusions or blemishes under 10x magnification.

Internally Flawless (IF)

  • These Diamonds have no internal inclusions but may have minor surface blemishes.

Very, Very Slightly Included (VVS1 and VVS2)

  • Inclusions are extremely difficult to detect even under 10x magnification.
  • These Diamonds offer exceptional clarity and brilliance.

Very Slightly Included (VS1 and VS2)

  • Minor inclusions are visible under 10x magnification but often not to the naked eye.
  • VS Diamonds offer excellent value for their clarity.

Slightly Included (SI1 and SI2)

  • Inclusions are visible under 10x magnification and may be noticeable without magnification.
  • SI Diamonds can offer good value, but clarity varies.

Included (I1, I2, and I3)

  • Inclusions are visible to the naked eye and may affect the Diamond's brilliance.
  • I-grade Diamonds are the most budget-friendly but may have compromised appearance.
