The Science of Value: Understanding the 4Cs
At Diamond Corps, we believe that education is the foundation of a sound investment. The value of a diamond is determined by the "4Cs"—Cut, Color, Clarity, and Carat Weight. While many focus solely on carat weight, the Cut is arguably the most critical factor, as it determines the stone's ability to reflect light and exhibit "fire." A poorly cut diamond, regardless of its size, will lack the brilliance required for high-end appreciation.
In the current global market, ethically sourced gemstones have seen a significant rise in demand. Diamond Corps operates with strict adherence to the Kimberley Process, ensuring that every stone in our inventory is conflict-free and documented from its point of origin. This transparency not only fulfills ethical obligations but also preserves the long-term resale value of the asset.
For those considering diamonds as a hedge against market volatility, Rare Fancy Colored Diamonds represent a unique asset class. Unlike colorless diamonds, these stones are valued for their scarcity and intensity of hue. With many of the world's primary sources for colored diamonds nearing depletion, the rarity factor continues to drive significant year-over-year growth in the auction and private sale sectors.

Frequently Asked Questions
What makes a diamond "investment grade"?
Investment grade diamonds typically possess high clarity (VS1 or higher), excellent cut grades, and are usually 1 carat or larger. Rare colored diamonds (Pink, Blue, Green) are also prime candidates for investment due to their extreme scarcity.
Are your diamonds conflict-free?
Yes. Diamond Corps strictly adheres to the Kimberley Process and the System of Warranties (SoW) to ensure all our gemstones are sourced from conflict-free regions and ethical mining operations.
Do you offer custom jewelry design?
While our primary focus is wholesale loose stones and investment assets, we partner with master goldsmiths to provide bespoke mounting services for our corporate and private clients.
How is the price of a wholesale diamond determined?
Wholesale pricing is based on the Rapaport Diamond Report, adjusted for the specific nuances of the stone's 4Cs and the current global supply-demand dynamics.
