Selecting the Best Diamond Ring

Hello Prince Charming’s! Thinking to propose to your princess very soon? Let me guide you in choosing the right diamond that she deserves.

Diamonds comes in different sizes, shapes, colors, carats, cuts and clarity. Although it was really tough to choose which one your princess will like, let me and my new friend Paul from explain to you the guidelines in choosing the best diamond proposal ring.

Have you ever heard of 4C’s in buying diamonds? Paul explained very well in his website that diamonds must be analysed by their cut, clarity, color and carat. In general, the 4C’s can greatly change the price and technical qualities that the stone possesses.

The Diamond 4C's


The cut determines how well a diamond absorbs and reflects light. The better the cut, the more sparkle the stone will have.

Proportions: the relative sizes and angles of the diamond’s parts and facets
Symmetry: the precision of the cut design, especially the facets
Polish: the smoothness and lustre of the diamond’s surface

The cut grades are referenced on a diamond’s certificate often using the GIA standards of Excellent, Very Good, Good, Fair and Poor. For the most part, the actual measurements are mainly on the laboratory reports.

TIP: Go for a Good or Excellent cut. If you are not sure on her shape preference, I would suggest a round cut will do. It is classic and a safer choice.


The clarity of a diamond refers to the amount/type of inclusions present in it. A diamond with lesser flaws inspected under 10X magnification receives a higher grade.

Flawless- No inclusions and no blemishes visible under 10x magnification

Internally Flawless (IF) - No inclusions visible under 10x magnification

Very, Very Slightly Included (VVS1 and VVS2) - Inclusions so slight they are difficult for a skilled grader to see under 10x magnification

Very Slightly Included (VS1 and VS2)- Inclusions are observed with effort under 10x magnification, but can be characterized as minor

Slightly Included (SI1 and SI2)- Inclusions are noticeable under 10x magnification

Included (I1, I2, and I3) Inclusions are obvious under 10x magnification which may affect transparency and brilliance

TIP: VS1-VS2 are most popular and value for money. They appear to look very clean and flawless in the naked eye.


The color of a diamond is rated on a scale of D – Z, with D being totally colorless and Z being a noticeable yellow. In the market, the range of D-F is highly sought after.

If you are on a tight budget, the color is unnoticeable if you buy a lower grade like K or L instead of a D. Your lady won’t even notice it at all. Unless you have enough to invest, I would suggest buying a D or a single colored diamond. Or just invest in a higher cut which is the most important factor in a diamond’s brilliance. The brighter the stone, the better.

TIP: Buy G-J color which appears to look like colorless in the naked eye and a value for money.


The carat weight refers to a specific measurement of how heavy the diamond is. Note: By itself, carat weight is not an indication of the stone’s physical dimensions.

TIP: Look for not so popular carat weight like 0.30, 0.50, 0.75 and so on. They are cheaper than the usual whole number carats. You can't barely see the difference if you buy a 0.80 to a 1 carat diamond.

As a beginner, hopefully you were able to learn a lot in this blog post. Just quick tips below:

- If you are aiming for a white Gold Ring setting, you may go for round cut with H-J color, or Princess/Emerald cut with G-I or Oval/Pear/Heart cut with F-H color.

- If you are aiming for a yellow Gold ring Setting, you may go for Round Cut K-M color or Princess/Emerald cut with J-K color or Oval/Pear/Heart cut with I-J color.

As I said earlier, Diamond color doesn't matter much as long as the cutting is excellent. But of course, this will all depend on your budget.
