The more cut a diamond have, the shinier it is. It is up to you to decide.

It is best to have a certificate to give assurance that the diamond is genuine.

First of all, CUT also covers the proportions of the diamond, such as pavilion angle, crown angle, total depth. When we discussed about cut, we focus on pavilion angle and crown angle mainly because that's where the light gets reflected. Overall, CUT is really the most important factor in determining the light play within the diamond:

Hemera is their own proprietary cut. Standard round brilliant is cut to 57 facets, while Hemera is cut to 101 facets. The main difference is that the one with more facets will have cover the diamond area with "smaller windows" whereby the sparkles will also be smaller, but a lot (because more windows). For the one with lesser facets, it will cover the same diamond area with "bigger windows", whereby the sparkles will be bolder.

It is also said that the extra sparkle (scintillation) will be at the expense of fire and brilliance as well: Read this article by Hearts on Fire. That's why I will prefer to stick with the traditional 57 facets which is well-proven over time to provide the optimum performance in all areas - Scintillation, Fire, Brilliance.

To me, extra facets is really sold by that "one (or few)" company to make it unique that the rest, other diamonds like these includes Gassan 121 (121 facets), Leo Diamonds (66 facets), Allove (81 facets). All said that they are the best, but it is more like a "they cut it, and they said it" scenario, unlike 57 facets, which has been standing there for so long as the standard.

The one thing that makes the diamond to have optimum performance is the proportions and the cut precision. Diamonds with excellent proportions will be called Ideal Cut, while diamonds that are Ideal Cut + excellent optical proportions, we will call it Super Ideal Cut, aka Heart & Arrows. Few reputable vendors for Hearts & Arrows include:

WhiteFlash (affiliate link)
High Performance Diamonds

You may refer to my blog post here.

I got mine from WhiteFlash and I set it locally by iDo Jewellery.

You may read about my experience with WhiteFlash here.

As for Heart Shape Diamonds, I was told that you have to view the actual diamond to see if you like it or not, and it is not as easy to choose as round brilliant. I have replied to another forumer here regarding Heart Shape Diamonds here.

Nevertheless, at the end of the day, it depends on what you like. And remember, everything looks beautiful in the shop. You probably can request the salesperson to view the diamond in the shop's back office, or go view under direct sunlight. It may help you to see which one can perform the best under various environments.s

And yes, certificates are important. Reputable labs include GIA and AGS. Some other labs may have standards that are not that strict, so have to beware.

Good luck and all the best!

Allow me to reply to you with regards to heart shaped diamonds as I recently just gotten one for my engagement ring.

You can't really judge the quality of a heart shape based on its 4Cs alone, as it does not have a set of predefined ideal proportions like the round brilliant. What you need to do here (if you are set on getting a heart) is that you need to personally look at the stone to see if you like its shape cuz no two heart shaped diamonds are alike.

For engagement rings, people typically look for slightly plump hearts cuz they appear "happier", as opposed to an elongated heart. Elongated heart shapes make it have an overall skinner outline and it gives you the feeling macam the diamond tak cukup makan haha.

That's all for this post bro. Don't wanna load you with too many info. Let me know if you require more details on heart shaped diamonds.

Yes, you are correct.

You can also go to Audreys to do price survey as well. Other overseas websites such as Enchanted Diamonds, Bluenile, JamesAllen, WhiteFlash, Brian Gavin, High Performance Diamonds can also  give you a rough estimate of diamond price. Just need to convert the price to RM.

You may noticed that Super Ideals (WhiteFlash A-Cut-Above, Brian Gavin Signature, Black by Brian Gavin, etc) selling price will usually be more expensive than normal Ideals because they take longer time to polish and there will be more diamond wasted to achieve the best optical precision possible.

For normal Ideal GIA, I think Bluenile is a good place to survey. You can consider to focus on their Signature diamond pricing.

Hope this helps. Good luck!

I am not sure about the value of heart shaped diamonds bro. But one thing I know, be it a round brilliant or heart shape or even an emerald cut, the diamond which you choose is going to be invaluable to your fiancee.

I got mine at JannPaul Singapore. Carat for carat, of course hearts are cheaper than rounds. So for the same amount of money, you are able to get a larger diamond if you go for heart shape.

There is a huge price jump at 0.7. So the best is to buy shy. Maybe a 0.68 or 0.69 could do the trick. Same goes for 0.5.

Lol. Just set a budget and stick to it bro. If 50-pointers and 70-pointers are too expensive, you can always consider 30-pointers or 40-pointers. There are better ways to spend the money saved.

He is true but to a certain extend. D to G colours have little noticeable difference only if the diamond is a well cut one. With bright flashes of light coming from the diamond all at once at different angles, it would be difficult to spot the colour difference. Plus, nobody is going to compare your diamond side by side lahh, unless he/she is an a$$.

If you are getting a round brilliant, go for the lowest clarity grade which is eye clean. VVS1 or VS2 does not affect light performance if their inclusions cannot be seen with the naked eye. The same cannot be said to the price though haha. If both are eye clean, why pay more for VVS1?

Time for some affiliate work:

Here are 2 diamonds that I picked from Black by Brian Gavin. Both are affiliate links (which means I will earn some commission if you buy via either links).

USD 2853 + USD 44 shipment (approximate) = USD 2897 (Convert to MYR + GST = RM 13292.04)
0.593 F VS1

USD 2891 + USD 44 shipment (approximate) =  USD 2935 (Convert to MYR + GST = RM 13466.40)
0.604 E VS2

I would prefer the F VS1 over the E VS2. You may think that the price is not worth it for that  F VS1 because for that price, it is close to the 60-pointer. If we based on market price, yes, it is not worth it because 0.593 is almost there, but not there yet. However, if we go into the details, you will noticed that the F VS1 is actually larger face-up compared to the E VS2.

F VS1 :  5.39 x 5.42 x 3.34
E VS2 :  5.38 x 5.40 x 3.33

The actual reason I will choose 0.593ct over the 0.604ct is because the H&A and idealscope of the 0.593ct looks better than the 0.604ct. But if you want paper value, then 0.604ct maybe a better choice because it is a 60-pointer.

Ring setting price may vary from RM 1000 - RM 3000 and beyond (I assume starting price is more expensive since the carat size is bigger).

You can consider settings from:
1. Memory Jewellery
2. Eumayco
3. iDo Jewellery
4. Frou Frou

Memory Jewellery should provide the best value, but I would recommend you to check with each of them first before making the final decision.

Ok, that's all with my affiliate work.

Bro....

Honestly speaking from my own experience, girl dont care what spec or how good is the diamond spec, all they care just how big is it and how shine it is visually....

So.... my advice... just buy the diamond ring that you feel visually nice within your budget....
I spent almost 1 months plus studying on diamond.... end up she just dont give a f to how good the spec of diamond...

The rock big big but looks like plastic, what's the point bro? Yes, I do agree that most ladies out there don't give any conceivable fooks on the 4Cs and all that crap. But in my opinion, the 4Cs are mainly for the buyer to know what he is getting himself into.

These tiny little rocks do not come cheap bro, for sure one would like to know more than just the carat weight.

It is actually a pretty good advice to buy something visually nice and within budget.

Gf dont give a f, you can always come here and we won't send you fly kite.
