Diamond Market Guide: Types, Value & Investments Tips

Jan 20, 2025

Everything You Need to Know About the Diamond Market

For centuries, diamonds have captivated people with their remarkable brilliance and durability. 

Whether they are being given as a symbol of love, used for industrial purposes, or simply admired for their beauty, diamonds hold a special place in our world. But behind the gleaming façade lies an intricate and fascinating diamond market.

As Baltimore’s trusted diamond experts since 1922, Samuelson’s Diamonds has helped countless clients navigate the complex world of diamond buying and selling. Let’s explore everything you need to know about these extraordinary gemstones and their market value.

The Fascinating Formation of Diamonds

You might wonder “What diamonds are made of?” These precious gems are pure carbon crystals formed deep within the Earth under extreme pressure and temperature conditions over billions of years. This unique formation process creates one of the hardest natural substances known to mankind, perfect for both jewelry and industrial applications.

Global Diamond Sources

Where are diamonds found? The world’s most significant diamond deposits are located in Russia, Botswana, the Democratic Republic of Congo, Australia, Canada, and South Africa. 

Each region produces diamonds with unique characteristics, contributing to their variety and value in the global market. As you can imagine, minerals with such value are often the subject of international trade agreements and regulations – and are often fraught with controversy.

That’s why you should take the time to know where a particular diamond is sourced from and whether it was ethically mined. This information can usually be found by asking the seller or checking for certification.

Found in Botswana, the Lesedi la Rona diamond is up for auction and valued at $70 million.

Understanding Diamond Varieties

When exploring types of diamonds, you’ll encounter several distinct categories:

  • Natural mined diamonds (think of traditional diamond engagement rings)
  • Lab-grown diamonds (a newer, more sustainable option)
  • Raw (uncut) diamonds (these come straight from the earth and are typically used for industrial purposes)
  • Colored diamonds (these rare gems come in shades such as pink, blue, and yellow)
  • Synthetic diamonds (also man-made like lab-grown, but with different qualities than natural or lab-grown)

Each type offers unique characteristics and value propositions, making working with experienced buyers like Samuelson’s essential to understand your specific needs.

The Art of Diamond Cutting

The most expensive diamond cut remains the round brilliant, but there are many beautiful options among types of diamond cuts, including:

  • Princess Cut
  • Emerald Cut
  • Oval Cut
  • Marquise Cut
  • Cushion Cut

Each cut showcases different aspects of a diamond’s natural beauty and affects its overall value. For instance, a round brilliant cut is known for its exceptional sparkle and brilliance, while an emerald cut highlights the diamond’s clarity and clean lines.

At Samuelson’s, our experienced team can help you navigate through these different types of diamond cuts to find the perfect one for your budget and preferences. We understand that every individual has their own unique style, and we are dedicated to finding the perfect diamond cut to reflect that.

Clarity: A Key Value Factor

What is good clarity for a diamond? You may think that the answer is simple: a diamond with no visible flaws or inclusions. While this may be true, clarity goes beyond just the absence of imperfections.

The clarity scale ranges from Flawless (FL) to Included (I3). For most buyers, VS2 or SI1 clarity grades offer the perfect balance of quality and value, appearing clean to the naked eye while maintaining affordability.

Diamond Values and Investment Potential

How much are diamonds worth in today’s market? Prices vary significantly based on the 4Cs (Cut, Color, Clarity, and Carat weight). For example, a one-carat round brilliant cut diamond might range from $2,000 to $14,000, depending on its characteristics.

Are diamonds a good investment? While they can maintain value over time, diamonds should be approached differently than traditional investments. Unlike stocks or bonds, diamonds offer unique considerations:

  • Each stone is unique, making valuation more complex
  • Market prices can fluctuate based on global conditions
  • The emotional and aesthetic value often exceeds pure investment potential
