Carat
Carat refers to the weight of a diamond
While carat influences size, the beauty of a diamond is determined by the balance of all four characteristics
CRAFTED WITH PRECISION
Sif Jakobs Diamond Collection is crafted in 14k yellow or 14k white solid gold with a polished finish and hand-set with responsibly sourced lab-grown diamonds. Our diamonds are TW (Top Wesselton) G–H colour and VS clarity, chosen for their quality and natural brilliance. Top Wesselton refers to diamonds in the near-colourless range, typically graded G–H on the diamond colour scale, meaning the diamonds appear bright and clear. VS clarity indicates very small inclusions that are typically not visible to the naked eye, ensuring a clean and radiant appearance. Each diamond is expertly cut and polished to maximise light reflection.
AMODERN APPROACH TO DIAMONDS
Lab-grown diamonds are created in controlled environments rather than mined from the earth and are often chosen as a modern alternative to traditional mined diamonds. Our lab-grown diamonds are created using renewable energy and are conflict-free by origin, offering the same beauty and durability expected from mined diamonds.
THE 4Cs: THE STANDARD OF DIAMOND QUALITY
Like all diamonds, our Sif Jakobs lab-grown diamonds are evaluated according to the internationally recognised 4Cs: Cut, Colour, Clarity and Carat. These four characteristics determine the overall quality, beauty and value of a diamond. Our manufacturing partner is a member of the Responsible Jewellery Council (RJC), an international organisation that sets high standards for ethical, social and environmental practices across the jewellery industry. This means our materials are part of a responsible value chain, supporting responsible working conditions, local communities and the environmental protection:
02
Colour
Colour measures the presence of colour in a diamond.
The grading scale ranges from D (colourless) to Z (light yellow or brown). All Sif Jakobs lab-grown diamonds fall within the near-colourless range, graded G–H colour.
03
Clarity
VS-quality
Clarity refers to the presence of natural inclusions or surface blemishes within a diamond. Clarity grades range from Flawless (no imperfections) to Included (visible imperfections). Sif Jakobs lab-grown diamonds are VS clarity, meaning inclusions are very small and typically not visible to the naked eye.
04
Cut
Cut refers to how well a diamond has been shaped and faceted. A well-cut diamond reflects light beautifully, creating the sparkle and brilliance diamonds are known for.
