Does size matter for diamond rings?


With the right amount of knowledge, the enthusiasm to ask the woman of your dreams for your hand, the exercise should be very pleasant. You will find out on this page the most important things to choose the ideal engagement ring.

What is the ideal size?

The ideal size for a diamond mounted alone on an engagement ring is quite simply the one you imagine perfectly on the finger of your beloved in several decades.

As we get older, the joints tend to thicken, and therefore the ring and the diamond look a bit small on a woman’s hands. By taking a diamond of an average size between 0.50 and 0.70 carats (5 to 5.75 mm approximately) you are guaranteed to offer a diamond of good size and not too ostentatious, for a still reasonable budget. This is the perfect engagement ring that will be worn even after 60 years of happiness.

Nothing of course prevents you from going beyond. You just have to keep in mind that the evolution of diamond prices according to their weight is exponential, and that diamonds represent a very large part of the price of the ring. It is not uncommon for the stone to represent more than 70% of the total budget of your jewel.

How To Choose Your Diamond Engagement Ring?

  • There are two types of engagement rings: simple with a central diamond only or accompanied with diamonds on the sides to enhance the center stone.

Why an independent gemology laboratory?

It is to ensure an objective evaluation of the diamond. There is always a conflict of interest if the person selling the diamond certifies it himself.

Why a diamond laboratory?

A good laboratory has the latest generation equipment. Certain characteristics such as the treatment or the artificial magnificence of a stone can only be detected by advanced machines.

Soon the moment of the marriage proposal?

You are preparing every detail, and you have found THE perfect 18k gold ring, but an unexpected question has crept into your choice. What diamond size to choose for the engagement ring? This question is not trivial. And here is our answer.

The size of a diamond: the carat

The quality, as well as the rarity and the price of a diamond, are determined by what are called 4Cs: Carat (its weight), Clarity (its purity), Cut (its cut quality) and Color (its color). And of course, this does not apply to rough diamond, only to cut diamond.

For the subject that interests us here, we will only focus on the size of the stone, the carat as well as its diameter (partly related to its weight). The carat is the unit of measure for the weight of the diamond, historically linked to the Carob seed. One carat equals 0.2 grams and about 6.40 mm for its diameter. And generally, the heavier the stone, the larger it is. The carat is therefore also a good indicator for defining the size of a diamond. If you want to know more about the 4 diamond quality criteria , it’s here.

Another important element, we are talking here about the most used diamond shape today for an engagement ring, a round cut diamond with 57 facets. A type of size that has existed since the beginning of the 20th century and which is today the standard that is found all over the world. However, if you want a slightly more original piece of jewelry, other sizes called fantasy exist (heart, pear, cushion, princess, etc.) but we will tell you about these stones in another article.

How many carats for an engagement ring?

In our opinion, it is preferable to offer a solitaire with a diamond of a size equal to or greater than 0.30 carats (4.25 mm approximately). This size is a good starting point to offer your future fiancée a piece of jewelry that she will enjoy wearing at 30, 40 or 50 and over (and yes, you have to see far).

In addition, below this size, you may not receive a laboratory certificate with your diamond (it corresponds to his identity card). We therefore advise you to avoid a diamond that would appear too small over the years and for which you will have less traceability and indications of its quality.

If you have the possibility, by choosing the ring together for example, do not hesitate to try several sizes of diamonds to better realize the volume of the stone on the hand, and thus make the right choice. And for a surprise, use your little finger, it’s always better than nothing.

Last Words for You

We also advise you to avoid all rings that would give the illusion of a solitaire (a single diamond) with the use of small diamonds. It is less expensive, of course, but much more fragile. Not to mention that this type of rings offers no possibility for future developments. For example, your partner will hardly be able to modify her ring or her style and even less transform her diamond into a pendant and we’re not talking about the maintenance cost with a setting that will be more fragile. In the end, this is an economy that could cost you dearly.
