Sapphires, with their striking blue hues and regal presence, are among the most cherished gemstones. When considering the purchase of a sapphire, many buyers focus on carat weight. However, carat weight alone does not tell the whole story about the size and appearance of the gem. This article delves into the details of how big a 2 carat oval sapphire really is, offering insights into its dimensions, cut, comparison with other shapes, and more.
Size Explanation
When we talk about the size of a sapphire, we must distinguish between carat weight and visual size. The carat weight refers to the gemstone’s mass, with one carat equal to 200 milligrams. However, this weight can be distributed differently depending on the gemstone’s cut and shape, affecting the stone’s dimensions and how large it appears.
For a 2 carat oval sapphire, its size can vary significantly based on the quality of the cut and the specific proportions used by the gem cutter. Unlike round diamonds, which have standardized proportions and cuts, sapphires, especially those of different shapes like ovals, can vary more in dimensions even at the same carat weight.
Average Dimensions
The average dimensions of a 2 carat oval sapphire typically fall within the range of approximately 9.0 to 10.5 millimeters in length and 6.5 to 7.5 millimeters in width. The depth of the stone can also vary but usually ranges from 4.0 to 5.0 millimeters.
To provide a clearer perspective, these dimensions can be likened to a small olive or the size of a small paperclip, providing a substantial presence on a ring or pendant. The length-to-width ratio of an oval sapphire also plays a crucial role in its overall appearance, with a common ratio being around 1.4:1 to 1.6:1. This ratio ensures the oval shape looks balanced and elegant.
Cut Proportions
The cut of a sapphire significantly influences its perceived size, brilliance, and overall aesthetic. Unlike diamonds, which have specific cut standards, sapphires can be cut in various ways to enhance their color and clarity. For a 2 carat oval sapphire, the cutter’s goal is often to maximize the color and minimize inclusions, while also achieving a pleasing shape.
Depth: 60-75% of the total width. This ensures the sapphire is neither too shallow (which can make it appear lifeless) nor too deep (which can make it look smaller from the top).
Table: 55-65% of the total width. A well-proportioned table allows for optimal light reflection, enhancing the stone’s brilliance.
A well-cut oval sapphire will have a balanced symmetry and exhibit minimal bow-tie effect, a common issue in oval and pear-shaped stones where a dark shadow appears across the center.
Comparison with Other Shapes
When comparing a 2 carat oval sapphire to sapphires of other shapes, it’s important to consider the visual spread or the face-up size. Oval sapphires generally appear larger than round sapphires of the same carat weight due to their elongated shape. This makes oval sapphires a popular choice for those looking to maximize the visual impact of their gemstone.
Round: A 2 carat round sapphire typically measures around 8 mm in diameter. While it may have a more traditional appearance, it doesn’t cover as much surface area as an oval cut.
Princess: This square or rectangular cut can vary, but a 2 carat princess cut sapphire might measure approximately 6.5 x 6.5 mm.
Cushion: This cut, with its rounded corners and pillow-like shape, usually measures around 7.5 x 7.5 mm for a 2 carat stone.
Emerald: A 2 carat emerald cut sapphire, known for its rectangular step cuts, might measure approximately 8.5 x 6.5 mm.
In terms of visual size, the oval cut often provides a more substantial appearance compared to other cuts of the same carat weight.
Visual Guides
Visual guides are essential for understanding the actual size of a 2 carat oval sapphire. Comparing the stone to common objects or providing visual representations can help potential buyers get a better sense of its size.
For instance, placing a 2 carat oval sapphire next to a standard US dime (which has a diameter of 17.91 mm) can illustrate the gemstone’s dimensions. Additionally, jewelers often use hand models or rings with stones of various sizes to demonstrate how a 2 carat oval sapphire would look when worn.
Online retailers may offer interactive tools where users can compare the sizes of different gemstones on a virtual hand or next to everyday items, further aiding in visualizing the true size of a 2 carat oval sapphire.
Setting Impact
The setting of a sapphire can significantly influence its perceived size and overall impact. Various settings can either enhance or diminish the visual presence of a 2 carat oval sapphire.
Solitaire: A solitaire setting, which features the sapphire alone, can highlight the stone’s size and shape. Prong settings in solitaires allow more light to enter the stone, enhancing its brilliance.
Halo: A halo setting, where the central sapphire is surrounded by smaller diamonds or sapphires, can make the central stone appear larger and more dazzling. This is an effective way to enhance the visual size of a 2 carat oval sapphire.
Three-stone: This setting features a central sapphire flanked by smaller stones. The side stones can enhance the overall size appearance while adding additional sparkle.
Bezel: A bezel setting, where the sapphire is encircled by a metal rim, offers a secure and modern look. This setting can sometimes make the stone appear slightly smaller but provides excellent protection for daily wear.
Each setting style offers different advantages and can be chosen based on personal preference and lifestyle.
Quality Factors
The quality of a sapphire is determined by several factors: color, clarity, cut, and carat weight (the 4 Cs). For a 2 carat oval sapphire, these factors will significantly influence its appearance and value.
Color: The most prized sapphires are those with a deep, vivid blue color, often referred to as “cornflower blue” or “royal blue.” The evenness of color and saturation also plays a crucial role.
Clarity: While sapphires often contain inclusions, those with fewer and less visible inclusions are considered higher quality. Eye-clean sapphires, where inclusions are not visible to the naked eye, are especially valuable.
Cut: As previously discussed, the cut affects the stone’s brilliance and overall appearance. A well-cut oval sapphire will exhibit excellent light reflection and minimal bow-tie effect.
Carat Weight: While a 2 carat sapphire is significant, the other quality factors can greatly influence its value. Larger carat weights are rare and often come at a premium, especially when combined with high color and clarity.
