Diamond Clarity Guide: What Matters Most

Understanding Diamond Clarity is essential when choosing a diamond, but higher clarity doesn’t always mean better value. Diamond clarity refers to natural inclusions formed during creation and plays a key role in overall diamond quality clarity. Many diamonds with lower grades still appear flawless to the naked eye, making them a smart choice for buyers seeking the best diamond clarity within budget. It’s also important to evaluate diamond color and clarity together, as balanced diamond color clarity enhances brilliance and beauty. By knowing what truly matters, you can confidently select the best clarity on a diamond that delivers sparkle, durability, and lasting value.

What Is Diamond Clarity?

Diamond clarity describes the presence of natural inclusions and blemishes within a diamond and is a key factor in determining diamond quality and value. As one of the 4Cs of diamonds, clarity is graded under 10x magnification based on the visibility of these imperfections. Higher diamond clarity enhances brilliance, light performance, and overall beauty. Understanding diamond clarity helps buyers choose diamonds that offer the perfect balance of luxury, sparkle, and price.

Does Diamond Clarity Really Matter?

Diamond clarity matters because it directly affects a diamond’s appearance, brilliance, and overall value. Higher diamond clarity means fewer visible inclusions, allowing more light to pass through and enhancing sparkle. As one of the 4Cs of diamond quality, clarity also influences rarity and pricing. Choosing the right diamond clarity helps buyers achieve the best balance between visual beauty, quality, and cost.

What is the clarity scale for diamonds?

The diamond clarity scale is a standardized system used to grade how free a diamond is from natural inclusions (internal features) and blemishes (surface marks). The most widely accepted system is defined by the Gemological Institute of America (GIA) and is used globally by jewelers and laboratories.

Clarity Grade	Full Name	Description	Visibility of Inclusions	Best For
FL	Flawless	No inclusions or blemishes visible under 10× magnification. Extremely rare.	Not visible under magnification or naked eye	Collectors and investment-grade diamonds
IF	Internally Flawless	No internal inclusions; only very minor surface blemishes.	Invisible to naked eye	Luxury and heirloom jewelry
VVS1 / VVS2	Very Very Slightly Included	Extremely tiny inclusions that are very difficult to detect even under 10× magnification.	Invisible to naked eye	High-end fine jewelry
VS1 / VS2	Very Slightly Included	Minor inclusions that are difficult to see under magnification.	Invisible to naked eye	Best balance of quality and value
SI1	Slightly Included	Noticeable inclusions under magnification, but often eye-clean.	Usually invisible to naked eye	Engagement rings and everyday wear
SI2	Slightly Included	More visible inclusions that may affect brilliance depending on placement.	Sometimes visible to naked eye	Value-focused buyers
I1 / I2 / I3	Included	Obvious inclusions that may impact brilliance and durability.	Visible to naked eye	Budget or fashion jewelry

What is Good Clarity For a Diamond?

Choosing the right diamond clarity is one of the smartest ways to get maximum beauty without overpaying. A good clarity for a diamond means the stone looks clean to the naked eye while maintaining excellent brilliance, durability, and value. Contrary to popular belief, you do not need a flawless diamond to enjoy a stunning sparkle.

Diamond clarity refers to the natural inclusions and blemishes formed during a diamond’s creation. These characteristics are graded under 10× magnification, but most of them are invisible in everyday wear. For this reason, the best clarity choice is one that appears flawless without magnification commonly known as an eye clean diamond.

Best Diamond Clarity for Most Buyers

For engagement rings and fine jewelry, VS1, VS2, and eye clean SI1 are considered the best clarity grades. These diamonds offer an excellent balance of appearance and price. Their inclusions are so small that they cannot be seen without magnification, allowing the diamond to look bright and clean while costing significantly less than flawless grades.

Why Higher Clarity Isn’t Always Better

While flawless and internally flawless diamonds are rare, they do not look noticeably different from VS or SI diamonds to the naked eye. Paying for extremely high clarity often means paying for details you will never see. Instead, choosing the right clarity allows you to invest in a better cut, size, or color factors that have a greater impact on beauty.
