What Color Diamond Is The Most Expensive? ›

Red diamonds are the most expensive colored diamonds. Currently, only about 20 to 30 exist in the world. These diamonds derive their red shade during the mining formation. The process is uncommon, explaining why red diamonds are rare and extremely small in size.

Which Diamond Color Is The Most Expensive? Despite the popularity of white diamonds, red diamonds take the prize for the most expensive diamond color. This is primarily due to their rarity.

By contrast, although white (not clear, but diamonds with a milky-white tone) and black diamonds are quite rare, they have not managed to capture the favour and attention of the public and are considered to be the least valuable of all coloured diamonds.

Topping our list of the most expensive diamonds in the world is the legendary Koh-I-Noor. Weighing in at a massive 105.6ct, the most expensive diamond in the world is oval-shaped. Steeped in mystery and legend, the stone is believed to have been mined in India in the 1300s.

According to that GIA standard, the "best" diamond color is D. (Read more about D color diamonds here). D color diamonds are the equivalent of IF or FL grade diamonds on the clarity scale — they're very rare, and their price definitely reflects that.

Red diamonds are the rarest of the colored diamonds, with only 20-30 existing in the entire world. They get their beautiful red color from a rare process during their formation, which changes the crystal structure of the diamond and causes light to pass through it differently than colorless diamonds.

The most expensive diamond with a monetary valuation is The Cullinan Diamond. Only The Kohinoor diamond is considered more valuable, but it has no price tag and is simply considered “priceless.”

Simulated diamonds are also known as diamond simulants and include things like cubic zirconia (CZ), moissanite, and YAG. They can also include some natural clear gemstones like white sapphire, white zircon or even clear quartz.

Color: Diamonds are graded on a color scale from D (colorless) to Z (light yellow or brown). Colorless diamonds, which are rarer, fall on the higher end of the scale and are more expensive. Cheaper diamonds may have noticeable coloration. Clarity: This refers to the absence of inclusions and blemishes.

Which cut diamond is the most expensive? ›

The most expensive diamond shape is by far, the round brilliant cut diamond. This cut has 58 facets to reflect the maximum amount of light, making it the most sparkly and brilliant of all the diamond cuts. The round cut diamond requires a lot of skill and precision to cut correctly, which adds to its high cost.

The best diamond clarity rating is Flawless (FL). These are the rarest diamonds in the world; less than 0.05% of all diamonds are Flawless or Internally Flawless.

1. The Cullinan Diamond. The largest diamond in history was discovered in the Premier Mine of South Africa in 1905. Named after the owner of the mine, Thomas Cullinan, the Cullinan Diamond was an incredible 3,106 carats — weighing nearly 1.4 pounds.

Because diamonds reflect white light, colorless diamonds produce the best sparkle and fire. In fact, the more color a diamond has, the less likely it is to reflect white light. And as a result, will produce less sparkle. A D-color diamond is the highest quality, and will offer the greatest sparkle.

White diamonds are given a color grade of D (colorless) to Z (light yellow). Tiffany only accepts engagement diamonds in the “colorless” and “near colorless” range on a diamond color scale. For engagement diamonds, Tiffany only accepts D, E, F, G, H and I color diamonds.

In terms of positioning along the diamond color scale, G color diamonds are more valuable than I color diamonds. But both are highly prized diamonds that make great center stones for engagement rings and other jewelry.

Fancy vivid blue diamonds are among the rarest and most sought-after gemstones, which often translates into higher prices. As a general guideline, you can expect the price for a fancy vivid blue diamond to start at around $100,000 per carat, for smaller stones with moderate color intensity and clarity.

If the stone is destined for jewelry, you will typically get more bang for your back buying a diamond just below the 1.00ct threshold. Visually, the slight difference in carat weight is meaningless; a 0.99 ct stone looks the same size as a 1.00ct.

Color is rated on a scale from D (whitest color) to Z (most yellowish color). D, E and F color diamonds are considered to be the rarest and most beautiful, and are therefore the most expensive. G through J color diamonds are considered good quality, while K through Z color diamonds are considered low quality.
