Learn About Ruby vs Diamond Value

When it comes to determining the value of precious gemstones like rubies and diamonds, there are several factors to consider. Whether you are looking to sell your old jewelry or simply want to learn more about these beautiful stones, it’s important to understand the differences in value and how they are calculated.

Ruby Valuation

When it comes to rubies, there are two main types to consider: synthetic and natural. Synthetic rubies are man-made and are  less valuable than natural rubies. Rubies are rare, beautiful, and highly sought after, mainly for their deep red color. The value of a ruby is based on the 4 C’s, cut, clarity, carat weight, and color, as are diamonds. However, unlike diamonds, rubies are cut dependent on the formation of the stone.

Rubies are formed in various ways, with different amounts of iron, which, along with chromium, gives them their red coloration. Depending on the formation of the stone, a flaw may make the final gem more beautiful and actually increase its value, which is the opposite of how flaws affect the value of diamonds.

The color of a ruby is probably the most important factor in determining its value. In fact, if they are too pink, they are considered to be pink sapphires and not rubies at all. The deeper the coloration, as with a blood ruby, usually the more valuable the stone.

Diamond Value

As noted above, diamonds are measured by the 4 C’s as well. The cut is one of the most important factors when determining the value of a diamond, as it affects the stone’s overall appearance and brilliance. The clarity of a diamond is also important, as it determines the amount of internal and external flaws or blemishes present in the stone. Synthetic diamonds are virtually undetectable from natural diamonds, but are priced at a significantly lower price point.

Ruby vs Diamond Value

When comparing rubies to diamonds, while they are both precious stones, there are several factors to consider. First, it is important to note that rubies are valued at about 1/10th of the value of diamonds per carat, with both synthetic diamond and synthetic ruby value being less than natural stones.

While rubies can be rare and highly valued, often based on their individuality, deep coloration, and setting, diamonds are more valuable by weight. Nevertheless, an extremely high quality ruby can be very valuable.

Additionally, diamonds have a higher hardness rating, which means they are more durable and will withstand more wear and tear over time. Nevertheless, rubies, which are formed from conundrum, are quite durable as well, with a Mohs scale (hardness scale) rating of 9.0 compared to the diamond which boasts a 10.0.

Transitional Cut Diamond Value

One type of diamond that is often highly valued is the transitional cut diamond. These stones became popular in the early 20th century, and are known for their unique shape and brilliance. Today’s modern round brilliant cut is a direct descendant of the transitional cut diamond, which was preceded by the old European cut.

As technology was developed during the early 1900s,  during a transitional period in diamond cutting history, these diamonds were cut using a combination of old world techniques and new diamond cutting technology. These diamonds are often highly sought after due to their rarity and unique beauty.

Know the Value of Your Fine Jewelry

In conclusion, when it comes to determining the value of precious gemstones like rubies and diamonds, there are many factors to consider. Whether you are looking to sell your old jewelry or simply want to learn more about these beautiful stones, it’s important to understand the differences in value and how they are calculated.

By considering the factors listed above,  you can gain a better understanding of the value of your precious gems and make informed decisions about their sale or purchase.

Customer Testimonial

Had a Great Experience

I have dealt in coins and metals since the 80s. Had dealings with many dealers. Got scammed by a few. Chicago Gold is the only one I would recommend to my family or friends. Have your valuables appraised by them before you sell.
