Hey there! As a supplier of Oval Ruby Corundum, I often get asked if there are different grades of this stunning gemstone. Well, the short answer is yes, there are! In this blog post, I'm gonna break down the different grades of Oval Ruby Corundum, what sets them apart, and why it matters to you as a buyer.
What is Oval Ruby Corundum?
First things first, let's quickly go over what Oval Ruby Corundum actually is. Corundum is a crystalline form of aluminum oxide and is one of the hardest naturally - occurring substances on Earth, second only to diamonds. When corundum has a red color due to the presence of chromium, it's called ruby. And when it's cut into an oval shape, we have Oval Ruby Corundum.
These gemstones are not only beautiful but also highly durable, making them a popular choice for jewelry, from rings and necklaces to earrings and bracelets.
The Different Grades of Oval Ruby Corundum
1. AAA Grade
The AAA grade is the crème de la crème of Oval Ruby Corundum. These stones have a vivid, intense red color that is uniform throughout the gem. The color is so rich and deep that it just pops, making it a real show - stopper.
In terms of clarity, AAA grade stones are almost flawless. They have very few inclusions, which are tiny imperfections inside the gemstone. These inclusions are so small that they are difficult to see even under magnification. This high level of clarity gives the stone a beautiful, transparent appearance, allowing light to pass through and reflect off the facets, creating a brilliant sparkle.
The cut of an AAA grade Oval Ruby Corundum is also top - notch. The oval shape is perfectly symmetrical, with well - defined facets that are cut to precise angles. This allows the stone to maximize its brilliance and fire, which is the dispersion of light into spectral colors.
2. AA Grade
AA grade Oval Ruby Corundum is also of excellent quality. The color is still very good, but it may not be as vivid or intense as the AAA grade. It could have a slightly lighter or more muted red tone, but it's still a very attractive color.
When it comes to clarity, AA grade stones may have a few more inclusions than the AAA grade. These inclusions are still relatively small and may not be visible to the naked eye, but they can be seen under moderate magnification. Despite these inclusions, the stone still has a good level of transparency and sparkle.
The cut of an AA grade stone is also quite good. The oval shape is mostly symmetrical, but there may be some minor irregularities in the facets. However, these are usually not noticeable to the casual observer, and the stone still has a nice amount of brilliance.
3. A Grade
A grade Oval Ruby Corundum is a step down in quality compared to the AA and AAA grades. The color may be less saturated, with a more pastel - like red tone. It might lack that deep, rich color that makes the higher - grade stones so eye - catching.
In terms of clarity, A grade stones have more inclusions. These inclusions can be more visible, and they may affect the transparency of the stone to some extent. Some inclusions may even be visible to the naked eye, which can slightly reduce the stone's overall beauty.
The cut of an A grade stone may also have some minor flaws. The oval shape may not be as perfectly symmetrical, and the facets may not be cut as precisely as in the higher - grade stones. This can result in a slightly less brilliant appearance.
4. B Grade
B grade Oval Ruby Corundum is considered a lower - quality option. The color is often pale and lacks the vibrancy of the higher grades. It may have a dull or washed - out look.
The clarity of B grade stones is significantly affected by inclusions. There are many inclusions, which can be large and easily visible to the naked eye. These inclusions can make the stone look cloudy or opaque in some areas, reducing its transparency and sparkle.
The cut of a B grade stone is also likely to have more significant irregularities. The oval shape may be distorted, and the facets may be poorly cut, resulting in a stone that doesn't have much brilliance or fire.
Why Grades Matter
The grade of an Oval Ruby Corundum matters for several reasons. Firstly, it affects the price. AAA grade stones are the most expensive because of their superior color, clarity, and cut. As you move down the grades, the price decreases accordingly. So, if you're on a budget, you might consider a lower - grade stone, but if you're looking for the best quality, the AAA grade is the way to go.
Secondly, the grade affects the appearance and durability of the stone. Higher - grade stones are more likely to retain their beauty over time. The better the clarity and cut, the less likely the stone is to chip or break. And a vivid, intense color is more likely to stay true over the years compared to a paler color.
