How shape affects 2 carat diamond price
One of the biggest factors that affects the price of a 2 carat diamond is the shape of the diamond.
Different shapes not only offer distinct styles but also vary in cost due to factors like cutting complexity, demand, and how much of the original rough diamond is retained during the cutting process.
The table below show the ranking of 2 carat diamonds by shape:
The Marquise cut is the most expensive, priced at $30,654. This high cost can be attributed to its unique shape, which requires precision cutting to maintain the diamond’s symmetry and brilliance. Additionally, there are not very many Marquise diamonds available at this carat weight, which means that the price can easily be skewed by some expensive stones. The Marquise diamond also tends to appear larger than other shapes of the same carat weight, adding to its allure and market value.
The Round brilliant diamond, priced at $27,567, follows closely behind. This shape remains popular due to its exceptional brilliance and light performance, making it a favoured choice for engagement rings and high-end jewellery. The complexity of the cutting process and the popularity of the shape contribute to its high price.
Oval and Pear-shaped diamonds, priced at $26,034 and $25,728 respectively, are also on the higher end of the price spectrum. These shapes are valued for their elongated forms, which create an illusion of a larger size, as well as being fashionable currently.
Radiant and Emerald cuts, priced at $25,161 and $24,877 respectively, are slightly more affordable. These shapes are appreciated for their distinctive step-cut facets and elegant appearance, although they do not exhibit the same level of brilliance as Round or Oval cuts.
Asscher and Heart-shaped diamonds, priced at $24,104 AUD and $22,859 AUD respectively, fall into the mid-range of pricing. The Asscher cut, known for its vintage appeal and deep clarity, and the Heart shape, symbolising love and romance, cater to specific tastes and occasions.
Cushion and Princess cuts are among the most affordable options, priced at $21,925 AUD and $21,124 AUD respectively. These cuts maximise the use of the rough diamond, minimising waste and reducing costs. Although they may appear smaller than other shapes of the same carat weight, they are popular choices for those seeking a balance between price and appearance.
Overall, the price variations among different 2 carat diamond shapes in Australia reflect a combination of factors, including cutting complexity, material loss, and market demand. This range of options provides buyers with diverse choices to suit their preferences and budgets.
