Internally Flawless Diamonds

Internally Flawless Diamonds

Internally Flawless diamonds sit just below Flawless diamonds on the GIA clarity scale and represent some of the rarest diamonds found in nature.

A diamond graded Internally Flawless (IF) contains no internal inclusions when examined under 10× magnification by a professional grader. The only characteristics that may be present are extremely minor surface blemishes, which can usually be removed with additional polishing.

Because there are no internal inclusions, Internally Flawless diamonds are exceptionally pure and extremely rare.

What Makes an Internally Flawless Diamond Special?

Internally Flawless diamonds are prized for their remarkable internal purity.

When examined under magnification, the interior of the diamond appears completely free of crystals, feathers, clouds or other internal characteristics. This level of purity is incredibly uncommon, making IF diamonds highly desirable among collectors and connoisseurs.

However, the visual difference between an Internally Flawless diamond and slightly lower clarity grades is almost impossible to detect with the naked eye.

How Rare Are Internally Flawless Diamonds?

Internally Flawless diamonds represent less than 1% of all diamonds mined worldwide.

Because of this rarity, they often command a significant premium in the market compared with diamonds in the VVS or VS clarity ranges.

For collectors seeking exceptional rarity, Internally Flawless diamonds can hold strong appeal.

Should You Buy an Internally Flawless Diamond?

While Internally Flawless diamonds are remarkable, they are not always the most practical choice for every buyer.

The key consideration is that clarity differences above VVS or VS grades are rarely visible to the naked eye. In most engagement rings and jewellery pieces, a carefully selected VS or VVS diamond can appear visually identical to an IF diamond once set.

For this reason, the decision to purchase an Internally Flawless diamond is usually based on rarity and prestige rather than visible beauty.

The MDT DESIGN Perspective

At MDT DESIGN, we believe that a diamond should always be selected for its overall beauty rather than simply its clarity grade.

While we are happy to source Internally Flawless diamonds for clients who value rarity, we often recommend carefully selected VS or SI diamonds where exceptional beauty can be achieved without unnecessary price premiums.

Every diamond we present to our clients is personally inspected to ensure it meets our eye-clean standard.
