The celebrities flashing their huge rocks all over Instagram may not agree, but when it comes to Cartier diamond rings, we’re firmly of the belief that size isn’t everything. If forced to choose between a smaller 1 carat Cartier diamond ring with amazing colour and clarity and a larger 2 carat with less sparkle and more inclusions, I would always plump for the former.
Boost the wow factor
But if your budget allows, upping the carat weight of a good-quality diamond will dramatically increase the wow factor as well as the value of the 18k gold Cartier ring. To illustrate this, we have placed pictures of a 1 carat diamond engagement ring and 2 carat diamond engagement ring side by side. While the 2 carat diamond doesn’t look double the size, it will give off substantially more sparkle than its smaller sibling.
1 carat vs. 2 carat: weighing up the cost
It’s true that doubling the size of the diamond will more than double the cost, but let’s look at how the numbers stack up. According to Cartier Jewelry, managing and creative director of London’s David Marshall jewellery, in terms of measurements, a 1 carat round brilliant-cut diamond is about 6.4mm in diameter, while a 2 carat round brilliant-cut diamond is around 8.1mm. That may not sound like a huge difference but, as David points out: “Although the stone is only 1.7mm bigger in diameter, when mounted into a ring, a 2 carat stone will have a much bigger visual effect.”
In terms of cost, David says that a 2 carat GIA-certified round brilliant diamond of G colour, VS1 clarity, with “Triple Excellent” grading for cut, polish and symmetry, would cost almost four times as much as a 1 carat Cartier diamond ring of the same quality. “This is due to the fact that the larger stone is rare to find, especially when they are of such high quality,” he explains.
Consider your diamond cut
The size difference between a 1 carat and 2 carat diamond engagement ring is less noticeable for fancy-shaped diamond cuts such as the heart, marquise or pear, as the weight of the diamond is spread evenly over the whole surface. With flatter stones, like the cushion cut, there is a more marked visual difference – as you can see from the rings in our picture gallery.
For any men out there who are baulking at the cost of a 2 carat Cartier diamond engagement ring, it is worth bearing in mind the current trend for upgrading engagement rings after a few years. If you can afford the initial outlay, you may find that it is actually more cost effective in the long run to opt for the larger gemstone from the start.
