The Answers:

First, we will have to put things into perspective. After we finish answering the questions concerning budget, personal preferences and tradition, we will touch the more technical stuff like diamond cut and size.
For the sake of simplicity we will divide the factors in two major categories. Personal Factors (your and your partner's taste, tradition and etc.) and the Technical Factors (diamond cut and carats)

Personal Factors on buying the perfect diamond engagement ring :



The first and most important factor is your partner's taste. Even if the cut or size is not the ideal one for this instance, if it is what you and your partner likes you should go for it. Our partner's excitement and happiness always come first! Do a mini-research on what your partner likes. See their saved jewellery on their pinterest boards, ask scouting questions and see the style of rings your partner prefers!! That way you will always be prepared and will have a clear picture of how the ideal ring for your partner will look like. After that mini-research you can use the information gathered to buy the ring you think is appropriate. Your partner's taste is the first and most important guide.


On the question "What is the role of customs and tradition behind my decision?" the answer is you have to go with your gut. Are you more of a traditional person? If yes you can go for a Princess or Brilliant cut Solitaire Diamond Ring. It really depends on whether you believe in tradition or not. If you do not care about traditional diamond rings you could go for a more daring design or choice of materials. Some examples are Sapphire Engagement Rings and Halo or Double Halo Diamond Engagement rings with usual diamond cuts. This choice is entirely up to you and your partner.


Budget is your foundation. It is how you will base all your options. Gauge your funds with caution. There have been instances where people took excessive loans in order to pay for fancy Diamond Engagement Rings and this led them to financial ruin! Save up some money and go for a ring that you can afford. The engagement ring is all about the gesture anyway. If you love your partner and your partner loves you back this ring will have a huge sentimental value for both of you, even if it's made out of tin!

It is a very modern and youthful design that shouts "love" like no other diamond cut.  Even though it is revered as the most romantic design -and we believe it is- it is not as popular as the other cuts. The reason must be that the shape of the heart makes the ring more difficult to match with everyday clothing.

Radiant Cut or Rectangular Modified Brilliant Diamond:

Baguette Cut Diamond:

The baguette diamond cut was developed around 1920 and is a really sought-after cut for diamond engagement rings, especially in Europe. This cut took its name from the French word @baguette that means thin loaf of bread.

The shape is minimal but with excellent sparkle making it an ideal, modest and stylish stone perfect for engagement rings.

The Way the Diamond is cut:

The diamond cut is chosen by the jeweller according to the following factors: The diamond quality, the diamonds shape and size, and the inclusions.  After careful examinations of these basic factors the diamond is finally cut and polished according to the shape that matches its profile. When a diamond is cut, regardless of the design that is selected there are some rules that need to be followed when it is cut in order to cut the diamond in such a way that will allow maximum light reflection.

The types of cuts are shallow, deep and idea. A diamond cut shallow A diamond cut is what determines its grading and therefore the price it is sold for. When cutting a diamond, the idea is to cut it to ensure the most amount of light is reflected. There are three types of cuts: shallow, ideal and deep. How carefully or skilfully your diamond is cut determines its value to a big extent. The shallow cut is not sought-after because it does not allow enough light in the diamond, the deep cut is similar to the shallow cut, but the light might be reflected back up. The ideal cut allows light to come through the stone and is reflected up.

The Diamond Size:

In Diamond Engagement rings the Diamond size is the first and foremost diamond specification to take a hit. And it is pretty understandable and acceptable. Not everyone was born rich, so affordable options  should still exist.
Usually, affordable engagement rings span from 0.20ct stones to half a carat. The reason why is that prices for bigger stones increase exponentially. Most people are puzzled as to what is an acceptable size for an engagement ring. The answer is simple. The size depends entirely on your budget so don't declare bankruptcy in order to get engaged. Save up some money, and see things clear. Buying engagement rings with smaller stones does not mean you do not love your partner enough.
