Best Carat Size for a Size 6 Finger

Across the U.S. women wear rings between sizes 5 and 7, with size 6 being the most common (16.45 mm). It's time to choose an engagement ring that complements it. It is wise to consider the finger type and hand shape of the recipient when choosing an engagement ring. This will help prevent beautiful rings from looking unflattering when you slip them on.

Carat weight and size are probably the first things that come to mind when you hear people talk about diamonds. Despite what most people think, carat weight isn't actually an accurate representation of the diamond's size. It is cut craftsmanship that can impact greatly both the actual dimensions and apparent size of the diamond. Considering carat weight and cut in tandem is a wise decision.
Our guide to the best carat size for a size 6 finger will provide the average engagement ring size, chart carat weight to millimeter size conversions, offer setting inspiration and tackle the all-important question: “is bigger always better”?

The Average Size of an Engagement Ring

Most people asking this question are in fact referring to the weight of the diamond, rather than actual size. Regardless of ring finger size, the concept of bigger is better is so ingrained in the minds of novice buyers in everything we purchase, it is easy to assume it also applies to diamonds and carat weights too.
However, average carat weight varies greatly according to age brackets, countries, and even cities, making it extremely difficult to determine an 'average' value. As a rule, one carat is equal to 200 milligrams, or one fifth of a gram.
Diamond Carat Weight
One carat is often considered the 'magic weight' by buyers of diamonds. According to statistics, the average diamond weight in the USA is about 1.00ct to 1.20ct, while the average diamond weight in the UK is about 0.60ct. There are many factors that can influence this figure, so it is not an exact science.
When it comes to balancing the four C’s, some buyers may be tempted to prioritize carat weight and place the majority of their budget in this area. Our advice would be to refrain from doing so, even though we respect everyone's personal preferences.

Is a Bigger Diamond Always Better?

Your diamond's carat weight influences how it looks, but it does not directly affect its size. The appearance of two diamonds of the same weight can differ greatly depending on how they carry the weight. There is no guarantee that a diamond will look bigger just because it has a higher carat weight.
A person's style, stature, hand size, setting preference, and budget should determine the most complementary stone size for your beloved. Our opinion is that not everyone would look great wearing an excessively large diamond on their hand every day. It does not suit the average lifestyle or those who are active in their daily lives.
Size is also highly subjective! In the opposite situation, a small diamond looks disproportionate on wider fingers. It would certainly help if you were able to visualize how the ring would look on the finger of your recipient when choosing the carat size. The best carat size for size 6 fingers is generally 0.50 carats or greater, as this tends to make them appear beautiful and balanced.

Prioritize Cut Over Carat

There is no doubt that a large diamond is desirable, but only if cut quality has not been compromised for size. Those with insufficient diamond education may wonder why their diamond doesn't sparkle. Generally, diamonds should not look too large or too small in relation to their carat weight; it indicates a poor cut and will reduce the stone's brilliance.
Shallow and Deep Cut Diamond chart
Often, diamonds are cut thicker or deeper at their girdle when they are proportioned for maximum carat yield. Consequently, diamonds appear smaller than their carat weight would indicate and often suffer from significant light performance deficits. Other times, cutting a piece of rough shallow can result in a diamond with a larger overall diameter. The diamond will also have weak light return as a result of this.
At Whiteflash, we emphasize cut as a fundamental element of the diamond buying process and indicative of diamond excellence.

In reality, there are no hard or fast answers since everyone has a different preference. Some carat sizes may appear too small or too large to you, but they could be the perfect size for another person. Or a larger carat might look proportionate on the finger, but not suit your significant other's active lifestyle.

Carat Weight To Millimeter Size Conversion

As stated above the relationship between carat weight and actual dimension varies according to the cut quality of the diamond. The average size for a woman’s hands with a finger size of size 6 is 16.45mm. The chart below provides an approximate conversion for well-cut round diamonds.

Choose the Right Setting for Size 6 Finger

It is impossible to have a 'normal' ring size. There is a great deal of difference between us. The length of our fingers varies between people; some have short, broad fingers, and others have long, slender fingers.
The type of setting you select will also dictate how big your diamond looks. A thin size 6 ring will not fit the same as a thick size 6 ring and thinner bands make the center stone stand out more. Using cathedral settings allows you to display your diamond high, halo settings create drama and presence on the hand, and side stone style rings add more visual impact.
