Open Crown
In the intricate world of diamonds, the “Open Crown” grade is a nuanced factor that evaluates the crown’s proportions and its alignment with the diamond’s overall geometry. The crown, the upper portion of a diamond above the girdle, plays a crucial role in the stone’s light performance and aesthetic appeal. Understanding our Open Crown grades, including CO0, NV, CO1, CO2, CO3, and NO OPCR, is essential for buyers aiming to make informed decisions that align with their preferences for brilliance and beauty.

- CO0 (Crown Optimal 0) : Signifies an ideally proportioned crown, perfectly complementing the diamond’s cut for optimal light reflection. Diamonds graded CO0 offer exceptional brilliance and fire. NV (Not Visible): Indicates that any deviations in crown proportions or alignment are not discernible or significant enough to impact the diamond’s visual quality under normal inspection.
- CO1 (Crown Optimal 1) : Denotes slight deviations from the ideal crown proportions, with minimal impact on the diamond’s light performance. Diamonds with a CO1 grade often display high brilliance and are visually stunning.
- CO2 (Crown Optimal 2) : Refers to moderate deviations in crown proportions, which might slightly affect light reflection and the diamond’s sparkle. While not as optimal as CO0 or CO1, CO2 diamonds can still possess considerable brilliance.
- CO3 (Crown Optimal 3) : Represents more significant deviations from ideal crown proportions, potentially diminishing the diamond’s light performance and aesthetic appeal. Diamonds with a CO3 grade may exhibit less brilliance and fire.
- NO OPCR (No Optimal Crown Proportions) : Implies a substantial misalignment in crown proportions, significantly impacting the diamond’s brilliance and overall beauty. Diamonds with a NO OPCR grade are likely to have compromised light performance.
When choosing a diamond, keep the following considerations in mind regarding Open Crown grades:
- Aim for Higher Grades for Superior Brilliance : If your primary concern is securing a diamond that radiates exceptional sparkle, focus on diamonds graded CO0 or CO1, as these are most likely to exhibit superior light performance.
- Balance with Budget Constraints : Diamonds graded CO0 typically command a premium due to their optimal light reflection. Diamonds graded CO1 and CO2 offer a good compromise, providing significant brilliance at potentially more accessible price points.

FAQ's
While the 4Cs (Cut, Color, Clarity, Carat) are the primary factors in determining a diamond’s quality and value, the Open Crown grade is an advanced consideration that further refines understanding of a diamond’s cut quality and potential for brilliance.
Open Crown grading is particularly pertinent to round diamonds and certain fancy shapes where the crown’s role in light reflection is pronounced. For unique or non-standard shapes, the relevance of Open Crown grades may vary.
Diamonds with higher Open Crown grades, such as CO0 or CO1, can be more expensive due to their enhanced light performance and desirability. Conversely, diamonds with lower grades like CO3 or NO OPCR might be priced lower, reflecting the potential impact on their brilliance.
The Open Crown grade of a diamond offers valuable insights into its cut quality and the potential for sparkle and fire. By considering Open Crown grades alongside the traditional 4Cs, buyers can choose diamonds that not only meet their aesthetic preferences but also offer the best value and visual appeal. Remember, the ultimate selection should resonate with your personal taste, ensuring your diamond is as unique and remarkable as the moments it will commemorate.
