Newbie here. After reading through the recent posts, my understanding is
Option 1: Other diamonds (with the same 4C criteria) with their "ideal cut" is like
- A Audi A 3 with 1 litre engine. (Cheaper)
- Look sleek on the outside.
- But if you dont open the hood and see (use scope and see), you will not know the normal ideal cut inside.
Option 2: JP diamond (with the same 4C criteria) with their strict selection of Ideal cut is like
- A Audi A 3 with 2 litres engine. (More expensive)
- Look sleek on the outside.
- But if you dont open the hood and see (use scope and see), you will not know the strict selected ideal cut inside.
Please correct me if I am wrong. Or can someone copy and paste the relevant post link for me to read.
The super ideal cut will definitely look sparklier than the ideal cut. But maybe your gf wants a bigger diamond? Then in that case, for the same amount of money (let’s say 6k), you can either choose to buy a smaller, sparklier diamond, or a bigger, still sparkly, diamond (but make sure it’s HCA below 2 and has a decent Idealscope image). Realistically, which one is still bigger for the same amount of money you paid?
The reason why people go to JP is because they want THE BEST. Let’s say you already know you confirm want a 0.5ct diamond. You don’t want anything bigger. Then sure, you can buy at JP and you will definitely be getting an OUTSTANDING diamond, best on the market.
Your analogy is a little mistaken because you WILL visually be able to see the difference between a super ideal cut and an ideal cut diamond. You won’t be able to see much difference in a jewellery store. But you WILL be able to see some differences in the sparkliness in natural light - it will be super extra sparkly.
Actually I am not sure if you are talking about JP Ideal cut vs. JP super ideal cut. But even their ideal cut is good because using the scope, there is no light leakage.
You CAN see light leakage in diamonds in daylight/natural lighting, it’s not like a car you just put there and don’t open the car to see inside. And you are likely to see it if the ideal cut from other shops do not have a fully red Idealscope image and HCA score less than 2. Many triple EX diamonds from China and India that are sold in Singapore are cut in 60-60 cut, which is definitely visually different from an ideal cut diamond when you compare both in natural light. And once you use an idealscope to check, they may have the black ring of death (inside the diamond not sparkling at all)/just not performing to their maximum ability, because their cut is too deep/steep. Why? Because the cutter is more interested in maximizing diamond size rather than cut. Duh. It will cost them more diamond raw material to cut a diamond with better cut (that’s why a diamond with HCA score less than 2 may be more expensive).
While the trend nowadays is HCA score less than 2 (diamonds with ideal cut proportions) and light performance with no white leakage on Idealscope image.
To fully answer your question, JP ideal cut diamonds are diamonds with HCA score less than 2 and good scope images. Can you find such diamonds in other shops? Yes, but make sure it also has HCA score 2 and decent Idealscope image to check for light leakage.
How about, is there a difference between JP ideal cut diamonds and any random diamond you buy from jewellery store that are NOT HCA less than 2? YES, there will be a super big difference if you take both diamonds and compare them sparkling next to a window. You WILL be able to visually see a difference (of course it depends on the random diamond since all diamonds are different). But the short answer is, because of the diamond proportions and because of the cut, it’s very likely that your random diamond is of inferior cut to an ideal cut diamond that follows ideal cut proportions.
