Hey there! I'm a supplier of Oval Ruby Corundum, and today I want to chat about how the clarity grade of this beautiful gem impacts its value. As someone who's been in the gemstone business for a while, I've seen firsthand how clarity can make or break a deal. So, let's dive in!

First off, what exactly is Oval Ruby Corundum? Well, it's a type of synthetic corundum that's cut into an oval shape. It's a popular choice for jewelry because of its vibrant red color, which comes from the presence of chromium in the crystal structure. But like all gemstones, Oval Ruby Corundum comes in different clarity grades, and these grades can have a big impact on its value.

Clarity refers to the presence of inclusions or blemishes in a gemstone. Inclusions are tiny imperfections that can occur during the formation of the crystal, while blemishes are surface marks that can be caused by handling or polishing. The fewer inclusions and blemishes a gemstone has, the higher its clarity grade.

There are several different clarity grades for Oval Ruby Corundum, ranging from flawless to included. Let's take a closer look at each grade and how it affects the value of the gemstone.

Flawless

As the name suggests, a flawless Oval Ruby Corundum has no inclusions or blemishes visible to the naked eye or under 10x magnification. These gemstones are extremely rare and valuable, and they're often used in high-end jewelry pieces. Because they're so perfect, they have a higher level of brilliance and fire, which makes them even more attractive to buyers.

However, flawless Oval Ruby Corundum is also very expensive. The rarity of these gemstones means that they're in high demand, and the price can be several times higher than a lower clarity grade. If you're looking for a flawless Oval Ruby Corundum, you'll need to be prepared to pay a premium.

Internally Flawless

An internally flawless Oval Ruby Corundum has no inclusions visible to the naked eye or under 10x magnification, but it may have some very minor surface blemishes. These blemishes are usually so small that they don't affect the overall appearance of the gemstone, and they're often considered to be part of its natural character.

Internally flawless Oval Ruby Corundum is still very rare and valuable, but it's not as expensive as flawless gemstones. Because they have a slightly lower clarity grade, they're a good option for buyers who want a high-quality gemstone without breaking the bank.

Very Slightly Included

A very slightly included Oval Ruby Corundum has very small inclusions that are difficult to see under 10x magnification. These inclusions are usually so small that they don't affect the overall appearance of the gemstone, and they're often considered to be part of its natural character.

Very slightly included Oval Ruby Corundum is more common than flawless or internally flawless gemstones, but it's still a high-quality option. Because they have a slightly lower clarity grade, they're a good option for buyers who want a beautiful gemstone at a more affordable price.

Slightly Included

A slightly included Oval Ruby Corundum has small inclusions that are visible under 10x magnification. These inclusions may be more noticeable than in a very slightly included gemstone, but they still don't affect the overall appearance of the gemstone.

Included

An included Oval Ruby Corundum has inclusions that are visible to the naked eye. These inclusions may be more noticeable than in a slightly included gemstone, and they may affect the overall appearance of the gemstone.

Included Oval Ruby Corundum is the most common clarity grade, and it's a good option for buyers who want a beautiful gemstone at a low price. Because they have a lower clarity grade, they're a good option for buyers who are on a tight budget.

So, how does the clarity grade of Oval Ruby Corundum impact its value? Well, as you can see, the higher the clarity grade, the more valuable the gemstone. Flawless and internally flawless gemstones are the most rare and valuable, while included gemstones are the most common and affordable.

However, it's important to note that clarity isn't the only factor that affects the value of Oval Ruby Corundum. Other factors, such as color, cut, and carat weight, also play a role. For example, a high-quality, deeply colored Oval Ruby Corundum with a good cut may be more valuable than a flawless gemstone with a lighter color and a poor cut.
