The Worth of a Ruby Diamond: Things You Need To Know

by Madonna

Rubies and diamonds are two of the most coveted gemstones in the world, known for their exquisite beauty and rarity. When these two precious stones come together in a single piece of jewelry, they create a dazzling and valuable combination. But determining the worth of a ruby diamond can be a complex process that involves several factors. In this article, we will explore the various aspects that contribute to the value of a ruby diamond and provide insights into how much one might be worth.

The formation process of rubies

Rubies, like sapphires, are a variety of corundum, and their formation is closely tied to geological processes. Rubies are typically formed deep within the Earth’s crust, in metamorphic environments where high pressure and temperature conditions prevail. The process begins with aluminum oxide-rich minerals, like corundum, coming into contact with specific elements like chromium or iron, which act as chromophores and impart the red color to the corundum crystals. Over millions of years, these minerals undergo intense heat and pressure, causing the corundum to crystallize and grow, eventually forming the vibrant red gemstones known as rubies. These gemstones are then often brought closer to the Earth’s surface through geological upheavals, such as volcanic eruptions.


Learn about Rubies and Diamonds

Before delving into the factors that influence the value of a ruby diamond, it’s essential to have a basic understanding of what exactly a ruby diamond is. A ruby diamond is not a natural gemstone but rather a term used to describe a specific type of jewelry. It typically features a diamond as the central stone, surrounded by smaller rubies or accentuated by ruby accents. This combination of diamonds and rubies creates a stunning contrast and a unique piece of jewelry that appeals to many.


The Four Cs of Diamonds

When evaluating the worth of a ruby diamond, the first aspect to consider is the quality of the central diamond. This quality is typically assessed using the “Four Cs,” which stand for Carat, Cut, Color, and Clarity.


1. Carat

Carat weight is one of the most significant factors influencing the value of a diamond. A higher carat weight generally translates to a higher price. However, it’s crucial to consider the carat weight in relation to the overall size of the ruby diamond and how well the diamonds and rubies complement each other. Sometimes, a smaller diamond in a well-designed piece can be more valuable than a larger diamond in a less appealing setting.

2. Cut

The cut of a diamond refers to how well it has been shaped and faceted. A well-cut diamond will have excellent sparkle and brilliance, which can significantly enhance the overall appearance of a ruby diamond. The precision of the cut is crucial, and diamonds with ideal cuts often command higher prices.

3. Color

Diamonds come in a range of colors, from colorless to various shades of yellow or brown. The most valuable diamonds are typically those that are colorless or near-colorless, as these are the rarest. However, in a ruby diamond, the color of the central diamond should harmonize with the surrounding rubies, creating a pleasing visual effect.

4. Clarity

Clarity refers to the presence of internal or external flaws, known as inclusions and blemishes, respectively. A diamond with fewer imperfections is considered more valuable. However, the clarity of the central diamond should be balanced with other factors, such as carat weight and cut, to determine its overall worth within the context of the ruby diamond.

Evaluating the Quality of Rubies

In addition to assessing the central diamond, the quality of the rubies used in a ruby diamond also plays a crucial role in determining its value. Rubies, like diamonds, are evaluated based on specific criteria.

1. Color

The color of a ruby is perhaps its most important attribute. The finest rubies are vivid red, often described as “pigeon blood” red. The presence of secondary hues, such as pink or purple, can diminish a ruby’s value. In a ruby diamond, the color of the rubies should complement the central diamond, creating a harmonious and visually pleasing combination.

2. Clarity

Just like diamonds, rubies can have inclusions and blemishes that affect their clarity. While some level of imperfections is acceptable, highly included rubies are less valuable. In a ruby diamond, the clarity of the rubies should be balanced with other factors to maintain overall visual appeal.

3. Cut

The cut of a ruby is essential for maximizing its brilliance and color. A well-cut ruby will showcase its vibrant red hue and sparkle beautifully. In a ruby diamond, the cut of the rubies should be carefully chosen to enhance the overall design and appearance.

4. The Setting and Design

The design and setting of a ruby diamond can significantly impact its value. A well-crafted and aesthetically pleasing design can command a higher price, even if the individual components, such as the central diamond or rubies, are not exceptionally large or high in quality.

The choice of metal for the setting, such as platinum or gold, can also influence the worth of the ruby diamond. Additionally, the craftsmanship and attention to detail in the jewelry piece are crucial factors that collectors and buyers consider.

5. Rarity and Uniqueness

Rarity and uniqueness are factors that transcend the individual qualities of the central diamond and rubies. A ruby diamond that features a rare combination of gemstones, a unique design, or historical significance can command a premium price. Collectors often seek out one-of-a-kind pieces, and their rarity can drive up their worth.

6. Market Demand and Trends

The value of a ruby diamond is also influenced by market demand and trends. As with any other commodity, the price of jewelry fluctuates based on supply and demand dynamics. Certain styles or designs may become particularly popular, leading to increased prices for similar pieces. Staying informed about current jewelry trends and market conditions can be essential for both buyers and sellers.

How to Identify and Certify Ruby Diamonds?

To determine the precise value of a ruby diamond, it’s advisable to seek the services of a professional appraiser. An experienced gemologist can assess the quality of the central diamond, the rubies, and the overall craftsmanship of the piece. They will provide a detailed appraisal report, which can be used for insurance purposes or when buying or selling the jewelry.

In addition to an appraisal, having a certification from a reputable gemological laboratory can add credibility and transparency to the transaction. Certifications from organizations like the Gemological Institute of America (GIA) or the International Gemological Institute (IGI) provide detailed information about the characteristics of the gemstones in the ruby diamond.

Historical Examples

To gain a better understanding of the potential worth of a ruby diamond, it can be helpful to look at historical examples of notable pieces that have fetched significant prices at auctions or private sales. For instance, the “The Red Emperor Necklace” featured a 2.62-carat Burmese ruby surrounded by diamonds and set in platinum. This exceptional piece sold for over $10 million at auction, highlighting the premium value placed on unique and high-quality ruby diamond jewelry.


Determining the worth of a ruby diamond involves a comprehensive evaluation of the central diamond, the quality of the rubies, the design and craftsmanship, rarity, market demand, and professional appraisal. A well-balanced combination of these factors can result in a ruby diamond of substantial value. Whether you are considering purchasing a ruby diamond or have one to sell, it’s essential to take all these aspects into account and seek the expertise of gemologists and appraisers to ensure a fair and accurate assessment of its worth. Ultimately, the allure and value of a ruby diamond lie in its ability to captivate with its exquisite beauty and rarity.
