Diamond Anatomy & Cut Quality
Understanding diamond anatomy and cut quality is essential when evaluating a diamond’s brilliance and beauty. The anatomy of a diamond consists of three main parts: the crown, pavilion, and girdle. The crown includes the top portion, where light enters, while the pavilion is the lower part that reflects light back, creating brilliance. The girdle, the outer edge, connects these sections.
Cut quality, the most crucial aspect, determines how well a diamond interacts with light. A well-cut diamond maximizes brilliance, fire, and scintillation by precisely balancing proportions, symmetry, and polish. Superior craftsmanship enhances a diamond’s natural allure, making it truly timeless.
Understanding the 4 C’s of Diamonds
The 4 C’s—Cut, Color, Clarity, and Carat Weight—are the universal standard for evaluating diamond quality. Cut determines brilliance, with precision shaping maximizing sparkle. Color measures the absence of hue, with the clearest diamonds being the most valued. Clarity assesses internal and external imperfections, ensuring visual purity. Carat Weight reflects a diamond’s size, with larger stones being rarer and more valuable. Together, these factors guide buyers in selecting diamonds that balance beauty, quality, and value.
Clarity
Clarity refers to the absence of internal inclusions and external blemishes in a diamond. Ranging from Flawless (no visible inclusions or blemishes) to Included (visible imperfections), each grade reflects the diamond’s unique characteristics. At AIDGL, we ensure precise clarity grading, enhancing your confidence in the diamond’s quality and value.
Diamond Clarity Descriptions
Diamond clarity refers to the assessment of a diamond’s internal characteristics (inclusions) and external imperfections (blemishes). It plays a crucial role in determining the diamond’s overall quality and value. Below are the standard clarity grades:
Flawless (FL):
No inclusions or blemishes visible under 10x magnification. Extremely rare and highly prized.
Internally Flawless (IF):
No inclusions and only minor surface blemishes visible under 10x magnification.
Very, Very Slightly Included (VVS1, VVS2):
Inclusions are extremely difficult to detect under 10x magnification. Requires an experienced grader to locate.
Very Slightly Included (VS1, VS2):
Minor inclusions that are somewhat easy to see under 10x magnification but not visible to the naked eye.
Slightly Included (SI1, SI2):
Noticeable inclusions under 10x magnification, with some potentially visible to the naked eye.
Included (I1, I2, I3):
Obvious inclusions that may affect transparency, brilliance, and durability. Often visible to the naked eye.
Each clarity grade reflects the unique characteristics of the diamond, ensuring its beauty and value are represented accurately.

N-Z (Light Color): Visible yellow or brown tones, typically less expensive, with unique character.
Color is a personal preference, and choosing the right diamond depends on your desired balance between brilliance, budget, and style.
