The 4 Cs (5 Cs for us) About Diamonds

Discover the allure of diamonds through the 4 C's: Cut, Color, Clarity, and Carat weight. These essential characteristics define a diamond's beauty and value. In addition to these traditional 4 C's, we introduce the 5th C, the Certificate. Our lab-grown diamonds, like their mined counterparts, come with certificates from renowned institutions such as IGI or GIA, ensuring their quality and authenticity. Explore the world of diamonds with confidence and transparency.

The 5 Cs


The cut of a diamond is not just about shaping its physical appearance but also unlocking its mesmerizing brilliance. The precision of the cut determines how effectively light interacts within the stone, giving rise to the diamond's sparkle and fire. At Lark & Berry, we offer the unique opportunity to craft diamonds in unconventional shapes, from unicorns to stars, or traditional cuts customized to reflect the profound depth of someone's love. The cut truly brings out the inner radiance of a diamond and allows us to create a symbol as unique as the love it represents.

The 5 Cs


The color of a diamond refers to the presence or absence of any hue in the stone. The Gemological Institute of America (GIA) grades diamonds on a scale from D (colorless) to Z (light yellow or brown). Truly colorless diamonds are exceptionally rare and highly valued. The presence of even subtle hints of color can impact a diamond's beauty and value. Therefore, a diamond's color grade is a crucial factor to consider when evaluating its quality and determining its overall aesthetic appeal.

The 5 Cs


Carat weight is a fundamental measure of a diamond's size, often serving as a key indicator of its value. One carat is equivalent to 200 milligrams, and diamonds are typically measured in points, with 100 points making up one carat. It's important to note that carat weight doesn't solely dictate a diamond's worth; other factors like cut, color, and clarity also play a crucial role. Larger carat weights often translate to more substantial and visually striking diamonds, but the interplay of all the 4 C's influences the overall beauty and desirability of a diamond. At Lark & Berry, we offer a range of carat sizes to cater to individual preferences, ensuring that you find the perfect balance of size and quality to celebrate your special moments.

The 5 Cs


Clarity is a critical aspect of a diamond's quality, describing the presence of internal and external imperfections or "inclusions" and "blemishes." These tiny, natural features are like a diamond's fingerprint, unique to each stone. The Gemological Institute of America (GIA) assigns clarity grades, ranging from "Flawless" to "Included," to assess the extent and visibility of these imperfections. A higher clarity grade indicates a diamond with fewer and less noticeable flaws, enhancing its overall brilliance and value.

At Lark & Berry, we understand the significance of clarity in a diamond's beauty. We meticulously select diamonds with exceptional clarity, ensuring that they exhibit minimal imperfections and deliver remarkable sparkle. Each diamond we offer is a testament to our commitment to quality and our dedication to helping you find a diamond that shines as brilliantly as your love story.

The 5 Cs


Certificates are the official documentation that confirms a diamond's quality, providing valuable information about its characteristics. These certificates are issued by renowned gemological laboratories, with the International Gemological Institute (IGI) and the Gemological Institute of America (GIA) being two of the most respected institutions in the industry.

What makes lab-grown diamonds exceptional is that they are certified in the same meticulous manner as their mined counterparts. Whether it's a lab-grown diamond or a naturally-mined one, both undergo the same rigorous evaluation process, encompassing the 4 C's: cut, color, clarity, and carat weight. This standardized certification ensures transparency and consistency in diamond grading, offering consumers confidence in their purchase. At Lark & Berry, we take pride in providing lab-grown diamonds with certificates from these esteemed institutions, assuring our customers of the quality and authenticity of their chosen diamonds.
