Understanding Diamond Pricing: The 4Cs

To grasp the worth of a one carat marquise diamond, we must first understand the foundational elements that determine diamond pricing: the 4Cs—Carat, Cut, Color, and Clarity.

Carat

Carat weight refers to the size of the diamond. One carat is equivalent to 200 milligrams, and this weight significantly impacts the price. As a rule of thumb, the higher the carat weight, the more expensive the diamond. However, this is not a linear relationship; for example, a 1.5 carat diamond does not cost one and a half times more than a one carat diamond. The price per carat typically increases as the carat weight increases.

Cut

The cut of a diamond influences its brilliance and sparkle. A well-cut marquise diamond will reflect light beautifully, making it appear larger and more dazzling. The cut is graded from Excellent to Poor, and diamonds with higher cut grades are generally priced higher due to their superior visual appeal.

Color

Diamonds are graded on a color scale from D (colorless) to Z (light yellow or brown). Colorless diamonds are rarer and more valuable. The ideal color range for marquise diamonds is typically G to I, where the diamond appears near colorless to the naked eye.

Clarity

Clarity refers to the presence of blemishes or inclusions in the diamond. The clarity scale ranges from Flawless (no inclusions visible under 10x magnification) to Included (inclusions visible to the naked eye). Higher clarity grades command higher prices.

Average Price of a One Carat Marquise Diamond

Based on current market trends, the price of a one carat marquise diamond typically ranges from £1,500 to £8,500, with an average price around £4,000. Various factors, including the 4Cs mentioned above, will influence where a specific diamond falls within this range.

The Unique Allure of Marquise Diamonds

Marquise diamonds are known for their elegant and unique shape. This cut, resembling a boat or an eye, maximizes the carat weight, making the diamond appear larger than its actual size. Here are some reasons why marquise diamonds are a popular choice:

  • Visual Impact: The elongated shape creates an impression of greater size, making it a favorite for those who want a bold statement piece.
  • Versatility: Marquise diamonds can be set in various styles, from classic solitaires to intricate halo designs, allowing for a personalized touch.
  • Historical Significance: The marquise cut has a rich history, dating back to the 18th century, and carries a sense of timeless elegance.

Setting Considerations

When selecting a marquise diamond, it’s crucial to consider the setting due to the diamond's pointed ends, which can be prone to chipping. A secure setting, such as a bezel or protective prongs, is recommended to safeguard your investment.
