They symbolize love, commitment, and luxury, making them a popular choice for engagement rings, wedding jewellery, and timeless pieces like diamond earrings, rings, necklaces, and pendants for every special occasion.
Colorless:
This is the most common and sought-after color, with “D” being the highest grade on the color scale, indicating no color.

Includes diamonds with slight hints of color, typically yellow or brown.
Fancy Colors:
These are rare and highly valuable.
The color of a diamond is influenced by trace elements within its structure.
Deep within the Earth: Natural diamonds are formed deep within the Earth’s mantle, under immense heat and pressure, over billions of years. Pure carbon atoms are subjected to extreme conditions, transforming into the incredibly hard crystals we know as natural diamonds.
Kimberlite and Lamproite Pipes: Diamonds are primarily found in kimberlite and lamproite pipes, which are volcanic conduits that brought the diamonds to the surface from the Earth’s depths.
Mining Operations: Mining companies extract diamonds from these pipes through open-pit or underground mining methods. This process involves significant investment and technological expertise.
Skilled diamond cutters, often with years of experience, meticulously shape and facet the rough diamond to enhance its beauty and brilliance. This process requires precision and artistry.
Gemologists assess the quality of the rough diamonds using various criteria, including the 4Cs:
Rough Diamond Sorting: Once extracted, the rough diamonds are carefully sorted based on their size, shape, color, and clarity. This initial sorting helps determine their potential value.
