How Much Does a Burmese Ruby Cost? The Definitive Guide

The short answer is: a Burmese ruby can cost anywhere from a few hundred dollars to millions of dollars per carat. The price is determined by a confluence of factors including color, clarity, cut, carat weight, and provenance. A small, heavily included Burmese ruby with poor color might only fetch a few hundred dollars. Conversely, a large, exceptionally clean, and vividly colored “pigeon’s blood” ruby from Myanmar could command millions at auction.

Understanding Burmese Ruby Value: The Devil is in the Details

Determining the value of a Burmese ruby requires a nuanced understanding of gemological principles and market dynamics. It’s not simply a matter of saying “Burmese rubies are expensive,” although, generally speaking, they are among the most valuable rubies in the world. Let’s delve into the key factors impacting price.

The Significance of Color

Color reigns supreme when evaluating any gemstone, and Burmese rubies are no exception. The ideal color for a Burmese ruby is often described as “pigeon’s blood.” This term evokes a vibrant, intense red with a slight fluorescence that makes the stone seem to glow from within. This fluorescence is a direct result of the low iron content in the Mogok region’s geological conditions where many of the most famous rubies are found.

However, it’s important to note that the term “pigeon’s blood” isn’t a universally standardized term. Different labs and appraisers may have varying interpretations. Generally, a ruby must exhibit a strong, pure red hue with minimal secondary tones of orange, pink, or purple to be considered true “pigeon’s blood.”

Rubies with secondary hues will be less valuable. Rubies that are too dark or too light will also not be worth as much. The intensity of the color is also extremely important. A deeply saturated color is most desirable.

The Impact of Clarity

Clarity refers to the absence of inclusions (internal flaws) and blemishes (surface flaws) in a ruby. While perfectly flawless rubies are virtually nonexistent, the fewer inclusions, the higher the value. Inclusions can impact the brilliance and durability of the stone.

However, certain inclusions, like fine needles of rutile silk, can actually enhance a ruby’s value by creating a phenomenon called asterism (a star effect) or contributing to the gem’s overall character. The key is the type, size, and location of the inclusions. Large, dark, or strategically located inclusions that detract from the stone’s beauty or pose a durability risk will significantly decrease its value.

The Importance of Cut

A well-executed cut is crucial for maximizing a ruby’s brilliance and color. The cut should be symmetrical and proportional to allow light to enter the stone, reflect internally, and exit through the top, creating a dazzling display of fire. A poorly cut ruby will appear dull and lifeless, regardless of its color or clarity.

The cutter must also consider the natural shape of the rough stone to minimize waste and preserve the largest possible carat weight. This balancing act requires considerable skill and experience.

Carat Weight: Size Matters (to a Point)

As with most gemstones, larger Burmese rubies are generally more valuable per carat than smaller ones. This is because large, high-quality rubies are exceedingly rare. However, the relationship between carat weight and price isn’t linear.

A 1-carat ruby might cost $5,000, but a 2-carat ruby of comparable quality could easily cost $20,000 or more. Beyond a certain point, the price per carat increases exponentially. Size is only one factor, but a huge ruby that lacks the other essential characteristics will not be worth as much.

The Power of Provenance: Where it Comes From

The origin of a ruby plays a significant role in its value. Burmese rubies, particularly those from the Mogok region of Myanmar (formerly Burma), are historically renowned for their exceptional quality and command premium prices. This is due to the unique geological conditions that produce rubies with intense color and strong fluorescence. Rubies from other locations, such as Mozambique or Thailand, may be beautiful but do not typically reach the same price levels as their Burmese counterparts. The location plays a big role due to color intensity, fluorescence, and iron contents of the area.

It’s important to note that not all rubies sold as “Burmese” are actually from Myanmar. Reputable gemological laboratories, such as the GIA (Gemological Institute of America), can provide origin reports that confirm a ruby’s geographic source.

Treatments and Enhancements

Many rubies undergo treatments to improve their color and clarity. Heat treatment is a common and widely accepted practice that can enhance a ruby’s color by removing unwanted secondary hues or improving its clarity by dissolving certain inclusions. However, more aggressive treatments, such as lead-glass filling, can significantly reduce a ruby’s value. A natural, untreated Burmese ruby will always command a higher price than a treated stone of comparable quality.

Frequently Asked Questions (FAQs)

1. What is “pigeon’s blood” ruby, and why is it so valuable?

“Pigeon’s blood” is a term used to describe a vivid, intense red ruby with a slight fluorescence. It’s considered the most desirable color for a ruby and commands premium prices due to its rarity and beauty.

2. How can I tell if a ruby is actually from Burma/Myanmar?

The best way to confirm a ruby’s origin is to obtain a report from a reputable gemological laboratory like GIA or SSEF. These labs use sophisticated testing methods to determine a ruby’s geographic source.

3. What is the difference between a ruby and a pink sapphire?

Both rubies and sapphires are varieties of the mineral corundum. The difference lies in the color. A corundum must be red to be classified as a ruby. Lighter shades of red or pinkish-red are typically classified as pink sapphires. It is a blurry line and up to the appraiser to categorize the stone.

4. Is it safe to buy a ruby online?

Buying a ruby online can be risky unless you’re purchasing from a reputable vendor with a solid return policy and a clear understanding of the gemstone’s characteristics. Always request a detailed description, high-resolution photos or videos, and a gemological report from a trusted lab.

5. What are common ruby treatments, and how do they affect value?

Common treatments include heat treatment, beryllium treatment, and lead-glass filling. Heat treatment is generally accepted and may have a minor impact on value, while beryllium treatment and lead-glass filling can significantly reduce a ruby’s value.

6. How do I care for a Burmese ruby?

Rubies are relatively durable gemstones. They can be cleaned with warm, soapy water and a soft brush. Avoid exposing them to harsh chemicals or extreme temperature changes.

7. What should I look for when buying a Burmese ruby as an investment?

Focus on high-quality stones with excellent color, clarity, and cut. Consider obtaining a gemological report from a reputable lab and purchasing from a reputable dealer. Untreated stones are generally considered better investments.

8. What is the Mohs hardness of a ruby, and why is it important?

Ruby has a Mohs hardness of 9, making it a very durable gemstone suitable for everyday wear. This hardness ensures that it is resistant to scratching.

9. Are synthetic rubies worth anything?

Synthetic rubies, created in a laboratory, have little to no resale value compared to natural rubies. However, they can be a more affordable option for those who appreciate the beauty of rubies but cannot afford a natural stone.

10. What is the best setting for a Burmese ruby?

The best setting for a Burmese ruby depends on your personal style and the size of the stone. Popular settings include prong, bezel, and halo settings. Gold and platinum are both excellent choices for metal.

11. How has the political situation in Myanmar affected ruby prices?

Political instability in Myanmar can disrupt ruby mining operations and supply chains, potentially leading to fluctuations in prices. Sanctions and import restrictions can also impact the availability and cost of Burmese rubies.

12. Besides color, what are some visual cues to help determine the quality of a ruby?

Look for even color distribution, sharp facet junctions, good brilliance, and minimal visible inclusions. Use a jeweler’s loupe to examine the stone closely. Check the stone under different lighting conditions to assess its color and brilliance accurately.

In conclusion, the price of a Burmese ruby is highly variable and depends on a complex interplay of factors. By understanding these factors, you can make informed decisions and find the perfect Burmese ruby for your budget and preferences. Always seek the advice of a qualified gemologist or appraiser before making a significant purchase.
