Understand the True Value of Rough Diamonds
The rough diamond price varies based on several key factors, including carat weight, color, clarity potential, crystal shape, and the diamond’s expected yield after cutting. Whether you are a jeweler, investor, or wholesale buyer, knowing the current market price of rough diamonds helps you make informed and profitable purchasing decisions.
At Goma Precious Minerals, we provide transparent, competitive pricing for natural, uncut rough diamonds sourced responsibly from trusted mining regions.
What Determines Rough Diamond Prices?
The price of a rough diamond is influenced by:
1. Carat Weight
Larger stones (5–20+ carats) are significantly more valuable due to rarity and cutting potential.
2. Clarity Potential
Gem-quality rough diamonds with minimal inclusions command higher prices than industrial-grade stones.
3. Color
Clear or near-colorless stones cost more, while fancy colored rough diamonds (yellow, brown, pink) follow their own market pricing.
4. Shape & Crystal Structure
Stones with strong cutting yield (octahedrons, dodecahedrons) typically have higher prices.
5. Market Demand
Global diamond demand, especially from manufacturers and wholesalers, affects price fluctuations.
