Diamond Clarity
Every diamond tells a story, etched in time, pressure, and heat. Clarity is the record of that formation — and one of the clearest signals of a stone’s rarity and value.
What is diamond clarity?
Clarity refers to the presence, or absence, of internal characteristics known as inclusions, and external characteristics called blemishes — natural markings formed deep within the earth under intense heat and pressure.
Completely flawless diamonds are extremely rare. Most inclusions are so small they can't be seen with the naked eye, and they do nothing to diminish a diamond's beauty. Not every diamond is perfect — but every diamond is one of a kind.
The five clarity categories
- Rarity at its finest. No visible inclusions even under 10x magnification.
- IF diamonds may carry minuscule surface blemishes, detectable only under a microscope.
- Fewer than 1% of diamonds meet this standard — an exceptional treasure.
- Inclusions are extremely difficult to detect under 10x magnification.
- These diamonds offer a nearly flawless appearance.
- Ideal for collectors or those seeking elite quality.
- Inclusions are minor and only visible under magnification.
- Excellent balance between beauty and value.
- Perfect for those who want purity without the premium price of VVS or FL.
- Inclusions are visible under 10x magnification, but generally invisible to the naked eye.
- SI1 diamonds often appear eye-clean and offer exceptional value.
- SI2 diamonds may show slight inclusions depending on location and cut.
- Inclusions are visible to the naked eye and may impact brilliance.
- Despite imperfections, these diamonds can still shine, especially with expert setting and styling.
- Best for clients seeking affordability with larger carat sizes.
