Solitaire diamonds are often more expensive due to several key factors:
Size and rarity: Solitaires usually refer to single, standalone diamonds. Larger diamonds are rarer than smaller ones, and the rarity increases exponentially with size. This rarity directly influences the price, making larger solitaire diamonds particularly expensive.
Quality emphasis: In a solitaire setting, the focus is entirely on one diamond. This means that qualities like cut, clarity, colour, and carat (the four Cs) are more scrutinized. High-quality solitaires without inclusions, with excellent cut and colour, are more expensive due to their desirability and rarity.
Cut precision: The cut of a solitaire diamond is crucial as it determines the stone's brilliance and fire. Achieving a cut that maximizes the diamond's reflective properties requires precision and can result in a significant loss of raw material. The expertise and material waste involved in cutting contribute to the cost.
Investment value: Diamonds, especially high-quality solitaires, are often considered investments. Their value can appreciate over time, making them not just a piece of jewellery but a financial asset.
Each of these factors contributes to the high cost of solitaire diamonds. The exact price will depend on a specific diamond's characteristics.
