The 4Cs of Diamond

The Ultimate Guide to Choosing the Perfect Diamond

When selecting a diamond, understanding the 4Cs—Cut, Color, Clarity, and Carat Weight—is essential. These factors determine a diamond’s beauty, quality, and value. At Liora Diamonds, we ensure that each diamond meets the highest standards, providing brilliance that stands out. Whether you're a jeweler, investor, or individual buyer, knowing the 4Cs of diamonds will help you make an informed decision.

1.Cut – The Sparkle Factor That Defines Brilliance

The diamond cut is the most crucial factor influencing its brilliance. Cut refers to how well a diamond’s facets interact with light, affecting its sparkle, fire, and scintillation. A well-cut diamond reflects maximum light, creating a mesmerizing shine and enhancing the diamond’s overall visual appeal.

EXCELLENT

VERY GOOD

GOOD

FAIR

POOR

Key Diamond Cut Grades:

Excellent Cut Diamond – Superior brilliance and fire, reflecting nearly all light that enters.
Very Good Cut Diamond – Impressive sparkle with minor imperfections in light reflection.
Good Cut Diamond – Balanced light reflection but with slight loss of brilliance.
Fair Cut Diamond – Some loss of light reflection, reducing brilliance.
Poor Cut Diamond – Limited sparkle due to improper proportions and shallow or deep cut.

Advanced Tip: Always prioritize diamond cut quality over carat weight for maximum brilliance. A smaller, well-cut diamond can appear larger and more radiant than a bigger, poorly cut one. Liora Diamonds specializes in precision-cut diamonds, ensuring optimal brilliance.

2. Color – The Whiteness Scale That Impacts Value

Diamond color grading is done on a scale from D (colorless) to Z (light yellow or brown). The less color a diamond has, the rarer and more valuable it is. The presence of color can impact the diamond’s brightness and overall aesthetic appeal.

Grade	Subgrade/Description
D, E, and F	Colorless
G, H, I, and J	Near Colorless
K, L, and M	Faint Yellow
N, O, P, Q, and R	Very Light Yellow
S, T, U, V, W, X, Y, and Z	Light Yellow

Diamond Color Grades:

D-F Color Diamonds – Completely colorless, offering the highest purity and value.
G-J Color Diamonds – Near-colorless, an excellent balance between price and appearance.
K-M Color Diamonds – Slight yellow tint, noticeable only in certain lighting conditions.
N-Z Color Diamonds – Obvious yellow or brown tint, more affordable but lower in value.

Advanced Tip: If you want a high-quality diamond at a lower price, opt for G-H color diamonds—they appear colorless to the naked eye but are more affordable than D-F color diamonds. Liora Diamonds offers an extensive selection of near-colorless diamonds with high brilliance.

3. Clarity – The Purity of a Diamond's Inner Beauty

Diamond clarity refers to the presence of internal inclusions and external blemishes. Since diamonds are formed under immense heat and pressure, inclusions are common. The fewer the imperfections, the higher the value and brilliance.

Category	Flawless	Internally Flawless	Very Very Slightly Included	Very Slightly Included	Slightly Included	Included
Grade	FL	IF	VVS1 / VVS2	VS1/VS2	SI1/SI2	I1/I2/I3

Category	Grade
Flawless	FL
Internally Flawless	IF
Very Very Slightly Included	VVS1 / VVS2
Very Slightly Included	VS1/VS2
Slightly Included	SI1/SI2
Included	I1/I2/I3

Diamond Clarity Grades:

FL (Flawless Diamonds) – No inclusions or blemishes, extremely rare and highly valuable.
IF (Internally Flawless Diamonds) – No internal inclusions, only minor surface blemishes.
VVS1, VVS2 (Very Very Slightly Included Diamonds) – Inclusions are microscopic and nearly impossible to detect.
VS1, VS2 (Very Slightly Included Diamonds) – Inclusions visible only under magnification.
SI1, SI2 (Slightly Included Diamonds) – Inclusions may be visible to the naked eye but still offer good value.
I1, I2, I3 (Included Diamonds) – Obvious inclusions that affect durability and brilliance.

Advanced Tip: A VS1 or VS2 diamond provides excellent clarity while being more affordable than a VVS or FL diamond. At Liora Diamonds, we ensure that each diamond has optimal clarity without compromising quality.

4. Carat Weight – Understanding Diamond Size & Price

Diamond carat weight measures the size of a diamond. While larger diamonds are more expensive, a well-cut diamond with a smaller carat weight can look bigger due to enhanced brilliance and optical symmetry.

Diamond Carat Weight Guide:

Advanced Tip: Choose a 0.90-carat diamond instead of a full 1.00 carat diamond to save significantly while maintaining the same visual impact. Liora Diamonds offers precisely measured carat weights to help you maximize your investment.
