Buying a Diamond: Size Vs. Quality

Buying a Diamond: Size Vs. Quality

When you are shopping for a diamond engagement ring, the question you might often encounter is: how big? Of course, your jeweler will say that it depends on your preference. Better yet, they will say that it is best to work within your allotted budget.

Before contemplating if you want a bigger diamond or a better quality diamond, it is best to go consider the 4Cs of diamond: carat weight, cut, color, and clarity. This way, you can maximize your budget and buy the best diamond engagement ring for your partner.

4Cs of Diamond Buying


The carat weight is the diamond’s physical weight measured in metric carats. A carat is about 0.200 grams with each carat subdivided into 100 “points”. For example, a 5-carat diamond weighs 1 gram. 

Do not confuse this as something that is synonymous with a diamond’s size. A bigger diamond might weigh heavier, but it is also affected by other factors like its cut, clarity, brilliance, and more.


The way a diamond is cut affects its beauty and aesthetics. It shows off how the light shines through it and how bright it can sparkle. More often than not, well-cut diamonds are more expensive because they sparkle more even if you have to choose a smaller diamond size or carat.


Diamonds are letter graded based on their color. A D grade is given to the whitest diamond while a Z grade means that the diamond is brownish, yellowish, or gray. Most diamonds on the market are between the F and J grades. 

However, color grades aren’t easily noticeable. You can compromise a little on your diamond’s color while still getting a ring with a beautiful diamond.


Diamonds are naturally-occurring. This means that there are instances when these stones have internal characteristics or “inclusions” that may look like blemishes. Large inclusions may be visible to the eye and may block the light shining through the diamond. However, many inclusions are only seen when magnified. 

This is also another factor where you can save money. It is better to choose a diamond with a lower clarity grade as long as it is well-cut and has good color.  

Size Vs. Quality 

Now that you know the 4 Cs of diamond buying, we can now go back to our original point. What is better, size or quality? Again, it depends. Diamond quality matters a lot, but the size is also a big factor. It all comes down to the wearer and what is available within your budget. 

Consider this:

Diamond quality can matter more than size.

The bigger a diamond is, the more its poor quality can be seen. If you are on a tight budget, it’s better to go for quality than size. 

If you truly want a bigger diamond, you can choose a diamond with a smaller carat flanked by smaller diamonds. Choosing rings with halo settings can also make your diamond look bigger than it actually is.

Your partner’s style, personality, and preference.

Observe your partner and the jewelry they choose to wear every day. Do they prefer simpler pieces or do they favor bold and loud accessories? If so, your diamond of choice could be based on these. 

You can also think about their work and lifestyle. If they work with their hands, a bigger diamond might get in the way of their work. On the other hand, a bigger diamond might contribute or add to the image they want to portray in their line of work. You have to select a ring that will be safe in whatever environment they work in. 

Remember, your partner will wear this ring for pretty much their whole life. It is best to select a diamond that will suit their style and taste. 

Diamonds have an image of purity and light. They are given as a pledge of love and worn as a symbol of commitment. — Peter Singer
