When it comes to everything and anything in life, celebrities always go above and beyond – we know that. Buying an engagement ring is no exception. So, which celebrity has the biggest and most expensive engagement ring out there?

Let’s dive into the history books and go through some of the biggest engagement rings worn by celebrities. Who do you think has or had the most expensive one? Lets firstly dive into how diamond rings are priced. You will be surprised that often the biggest diamond is not always the most expensive.

Bigger doesn’t always mean “Better”

The bigger the ring the more it costs right? Not quite. When it comes to measuring the value of a diamond, it is usually broken down into four factors. These are known as the ‘Four Cs’ – Cut, Colour, Clarity and Carat.

No anyone diamond is the same, just like not any one person is the same. In the world of jewellery, the Four Cs are used to determine the value and rarity of each diamond, which of course makes the engagement ring unique as well and determines its price and value.

So, what exactly do the Four Cs mean?

Cut: The ‘Cut’ of a diamond refers to the quality of how the diamond is proportioned and how many angles and symmetrical facets it has. These impact how the diamond sparkles when it is hit by light. The GIA (Gemological Institute of America) will use a grading system to evaluate the diamond cut based on the criteria – ‘Excellent, Very Good, Good, Fair and Poor’.

Colour: The ‘Colour’ of a diamond is also based on GIA grades using scale D to Z. When it is a ‘D’ grade it is referred to as ‘colourless’, meaning the diamond is clear. As it goes down the scale, this means the diamond has brown and yellow tints to it. The colour might not be noticeable to the naked eye, but the price point is very different.

Clarity: The ‘Clarity of the diamond is determined by the blemishes and imperfections the diamond has. This is based on the GIA scale from ‘FL’ (flawless) to ‘I2’ (Inclusions 2). Of course, the more flawless the ring, the higher the price.

Carat: The ‘Carat’ of the diamond is determined by the carat weight. This is the weight of the diamond, not how large it is in size. Although the carat weight is a factor for ring price, it isn’t the only factor to consider when buying a ring. The appearance of the diamond plays a much bigger role in its value.

Now that you understand how a diamond is priced, which celebrity has the most expensive and biggest diamond ring?

Most Expensive Celebrity Engagement Rings

As mentioned, the size of the ring does not always play a big role in the rarity of a diamond ring. Often it is not the weight of the ring, but also how pure the diamond is, that is a leading factor for how it is priced.

However, in the world of Hollywood and celebrities, it appears the price and the carat go hand in hand for the biggest engagement ring. Famous singer, Mariah Carey reported having the biggest and most expensive diamond ring in the celebrity world. Her engagement ring, which she wore for only a short time, was 35-carats and was priced at $10 million. Given to her by her ex-fiancé James Packer (Australian’s really do know diamonds, right?). Although the couple split, Mariah kept the ring, continued to wear it for 12 months and then sold it for $2.1 million.

Going back through time, Elizabeth Taylor held the most expensive and biggest engagement ring in her possession for quite a while. The actress was married a few times, but it was the ring given to her by Richard Burton that was the grandest. The value of the ring was around $8.8 million when it sold at auction in 2011, but this engagement ring was an impressive 33.19 carats!

Here is a list of some other very big and outstanding engagement rings worn by celebrities:

  • Queen B, Beyoncé, is flashing one of the world’s highest-valued diamonds, weighing in at 24 carats and was bought for around $5 million in 2008.
  • Kim Kardashian’s famous $4 million engagement ring was around 15-carats but was stolen during the Paris robbery both her and Kanye experienced in 2016.
  • Paris Hilton has been lucky twice with two very large and expensive engagement rings. She firstly had a 24-carat ring to her first engagement in 2005, which she auctioned off for charity. But her latest engagement ring given to her by Chris Zylka was a 20-carat ring worth around $2 million, which she lost in a nightclub.
  • When Grace Kelly got engaged to Prince Rainier III (before she became Princess Grace), her emerald-cut was 10.47 carats and was worth around $5.2 million

The list of expensive and big engagement rings goes on and on! So how do the other half live??
