When choosing a diamond, one of the most common questions buyers ask is: Rough diamonds vs polished diamonds – what’s the difference? Understanding how diamonds transform from natural raw crystals into brilliant polished gemstones can help you make a more informed buying decision.
At Shree Diamond Mfg, we specialize in both rough diamonds and polished diamonds, supplying premium-quality stones at wholesale prices to global buyers. In this guide, we’ll explain the key differences, benefits, pricing, and best use cases for each type.

Price Difference: Rough vs Polished Diamonds
One major difference between rough diamonds vs polished diamonds is pricing. Rough diamonds cost less because:
-

Final quality is not guaranteed
Polished diamonds cost more because:
-
They are finished gemstones
-
Cutting increases value
-
Certified quality assurance
If you're looking for investment-grade or ready-to-wear jewelry, polished diamonds are ideal. For custom designs or manufacturing, rough diamonds offer flexibility and cost benefits.
