The Journey of Diamonds: From Rough to Polished

Introduction to Diamonds

Diamonds are one of the most sought-after gemstones in the world, prized for their brilliance, durability, and rarity. From their formation deep within the Earth to their transformation into stunning polished stones, diamonds undergo a fascinating journey. This blog explores the processes of rough and polished diamonds, fancy colored diamonds, the Kimberly Process, and their origins in Zimbabwe, Botswana, Sierra Leone, South Africa, Angola, and the Democratic Republic of Congo (DRC).

We specialize in colored and fancy diamonds, offering a wide range of unique and rare gemstones that cater to the most discerning tastes.

Stage 1: Rough Diamonds

Rough diamonds are the raw, unpolished stones extracted from the Earth. They are formed under extreme pressure and temperature conditions deep within the Earth's mantle. These diamonds are mined from kimberlite pipes or alluvial deposits.

Characteristics of Rough Diamonds:

• Natural Form: Uncut and unpolished, retaining their original shape.
• Color Variations: Can range from colorless to shades of yellow, brown, or even rare colors like blue and pink.
• Inclusions: Often contain natural inclusions, which are used to identify their origin.

Rough diamonds are carefully sorted and evaluated based on their size, color, and clarity before being sent for cutting and polishing.

Stage 2: Polished Diamonds

Polished diamonds are the result of cutting and polishing rough diamonds. This process enhances the stone's brilliance, fire, and scintillation, transforming it into a dazzling gemstone.

Key Steps in Polishing:

• Cleaving: The rough diamond is split into smaller pieces.
• Cutting: The diamond is cut into a specific shape, such as round, princess, or emerald.
• Polishing: The diamond is polished to achieve a smooth, reflective surface.

Polished diamonds are graded based on the 4Cs: Carat, Cut, Color, and Clarity.

Fancy Colored Diamonds

Fancy colored diamonds are some of the rarest and most exquisite gemstones in the world. These diamonds come in a variety of colors, including yellow, blue, pink, green, and red. Their unique hues are caused by trace elements or structural anomalies during their formation.

Why Choose Fancy Diamonds?

• Uniqueness: Each fancy diamond is one-of-a-kind, with its own distinct color and character.
• Rarity: Colored diamonds are extremely rare, making them highly valuable.
• Versatility: Perfect for creating unique and personalized jewelry pieces.
