What Defines Diamond Quality
Cut
The way a diamond is shaped and faceted, affecting its brilliance and sparkle.
Clarity
Refers to internal or surface flaws; fewer inclusions mean higher clarity and rarity.
Color
Measures how colorless a diamond is the less color, the more valuable and radiant.
Carat
Indicates the diamond's weight not always size but plays a big role in value.
Cut
Cut determines how well a diamond reflects light, giving it that signature sparkle. It’s not about shape it's about symmetry, proportions, and polish.
Even a perfectly clear diamond can look dull if poorly cut. A well cut diamond will shine brightly, capturing and reflecting light beautifully.
At Katanoff, we prioritize precision cuts that bring out maximum brilliance because cut is what brings a diamond to life.
Excellent
Reflects nearly all light that enters. Maximum brilliance, fire, and sparkle only 3% of diamonds achieve this superior grade.
Color
Diamond color refers to the presence of any hue within the stone, with truly colorless diamonds being the rarest. The less color a diamond shows, the higher its value and brilliance. Lab-grown diamonds are graded on the same scale as natural ones—from colorless to lightly tinted, and even rare fancy hues.

Diamond Appearance
D Is The Whitest Possible Color, But An Untrained Eye Will Not Notice A Difference Between D, E And F.
Diamond Considerations
These are the highest-quality color grades available. D is absolutely colorless, while E and F show virtually no detectable hue even under magnification. These diamonds are incredibly rare and prized for their icy white brilliance, making them ideal for platinum or white gold settings where purity and sparkle are everything.
Clarity
Clarity measures internal flaws or blemishes in a diamond, affecting its rarity not always its visible beauty.
Flawless (FL)
No internal or surface imperfections visible under 10x magnification. Extremely rare, highly prized, and represents the highest clarity a diamond can achieve.
Carat relates to weight, not size
