1.5 Carat Diamond

Congratulations on your impending nuptials! You’re probably planning on getting an exquisite engagement ring for your partner. You’ve established the appropriate  diamond color for them. Also, you’ve determined the right cut and clarity you’re looking for. But for some reason, you can’t seem to wrap your head around the right carat weight to buy. You weigh the various options available, and then decide to settle on 1.5 carats.

If you’re a savvy jewelry shopper, your decision to settle on 1.5 carats and not, say, 1.4 or 1.6 carats, is likely inspired by a profound understanding of diamonds. However, some buyers would opt for 1.5-carat diamonds purely on cost considerations. Perhaps they were looking for a 2.0 carat but found the price a bit expensive for them. So, in an attempt to secure the best bargain, they settled on 1.5 carats, thinking the cost would be much lower. Well, it doesn’t always work out that way in the jewelry industry. In this post, we shall explore the 1.5-carat diamond, so you can examine whether it’s an excellent fit for you.

Why A 1.5-Carat Diamond?

1.5 lies midway between 1 and 2. When shopping for diamonds, customers that prefer the invincibility of the stone would go for 1.0 carats. On the other hand, those who love the glamour and sparkle that diamonds bring out are likely to settle for 2 carats. The price also plays a significant role here. A 1.5-carat diamond is expected to be considerably cheaper than a  2-carats diamond. Of course, subject to all the other factors remaining constant.

From the illustration above, it’s evident that 1.5-carat diamonds enable you to enjoy the best of both worlds. You end up with a stone that’s small enough to retain its chic appearance, and big enough to be eye-catching. If you’re fortunate, you may actually come across a 1.5-carat diamond that’s priced half as much as a 2-carat diamond, even if the stones are similar in all other aspects. Many diamond shoppers, especially women, generally believe that 1.5-carats is the ideal diamond weight.

However, you probably already know that when buying diamonds, each customer has their unique tastes and preferences. Therefore, before you go shopping for a 1.5-carat diamond, you must already have determined its suitability for your needs. Another thing to remember is that as a jewelry shopper, the cost consideration should always come last.

So first, you’d need to settle on your preferred color, cut, and clarity, which we believe you’ve already taken care of at this point. As such, your only remaining concern is choosing the ideal carat weight.

Forget the popularity that accompanies the 1.5-carat diamonds. As a diamond shopper, the first thing you should establish is whether you are comfortable with the size. And as you know, size can be quite relative - what works for you might not work for the lady next door.


How Big Is A 1.5 Carat Diamond?

A 1.5-carat diamond has a diameter of 7.4 mm. That’s 1.0 mm larger than the diameter of a 1-carat diamond, and 0.6 mm smaller than that of a 2-carat diamond. Besides, 1.5-carat diamonds feature a face-up surface area of 43mm 2, which is roughly 18% smaller compared to that of 2-carat diamonds. So, everything considered, a 1.5-carat diamond is truly outstanding. It can stand out even better depending on the hand of the wearer, as well as the ring on which it’s set. The smaller the hand or ring, the more prominent the diamond will look.

But as you may expect, the size of a 1.5-carat diamond depends on a few other factors. Generally, the size comes down to the balance of the Four Cs. It’s not unusual to come across a 1-carat diamond that looks larger than a 1.5-carat stone. Neither is it surprising to find a 2-carat diamond looking significantly smaller than a 1.5-carat diamond.

diamond cut is the most critical element of the Four Cs that influence the size of a 1.5-carat diamond. In this regard, Asscher and round cuts tend to look smaller. On the other hand, marquise, oval, emerald, and pear cuts give a much better illusion of size.

The following table illustrates the surface areas of 1.5-carat diamonds across popular cuts.

6.4 x 6.4
Heart 7.5 x 7.5
7.4 x 7.4
6.3 x 6.3
7.2 x 5.8
10.4 x 6.2
7.6 x 5.7
9.3 x 6.2
11.9 x 6
6.7 x 6.7

Apart from the diamond cut, color is another critical consideration when shopping for a 1.5-carat diamond. Again, diamonds handle color differently depending on their cut and clarity score. Larger diamonds tend to reveal more tint. That means all other factors kept constant; a 1.5-carat diamond is likely to give more sparkle than a 1-carat diamond. The fire and brilliance of a 1.5-carat stone will also depend on the color of the ring where you set it. For instance, yellow and white rings tend to enhance the color of a diamond.

Pear, Marquise, and Oval shapes feature elongated corners. Therefore, they trap more light and color. If you were to select from among these three based on the light-handling properties, your best bet would be to go for anything above H in the diamond color scale. On the other hand, Round, Cushion, and Princess Cuts have shorter ends. As such, they reflect minimal light and color. When choosing a 1.5-carat diamond from any of these categories, experts generally recommend going for the color of H, and a clarity of VS2.

The Asscher and Emerald cuts are probably the most sensitive shapes when it comes to color-handling properties. As these shapes feature large windows that stretch into the depth of the diamond, they’ll reveal even the slightest color hues and imperfections. If shopping for a 1.5-carat diamond from between these cuts, you can consider color H and a clarity of VS1.

Another significant element that will impact the size of your 1.5-carat diamond is its clarity. And clarity all depends on what the shopper finds eye-clean. Flaws and inclusions affect a diamond’s ability to absorb and reflect light. Therefore, a flawed 1.5-carat diamond will look smaller than it should. So, always go for transparent diamonds that are eye-clean.

Lastly, if you’re looking to enhance the size of your 1.5-carat diamond, find it a decent setting. The halo setting is one of the top recommendations here. It features small diamonds surrounding the center stone. Anyone looking from afar would think it’s one large stone. You might also consider using pave rings with slightly-tapered shanks. Some common mounting styles to avoid include the bezel and the 3-stone design. Such settings are designed to bring out the shape of the stone, not necessarily its brilliance.

How Much Does a 1.5-Carat Diamond Cost?

It can range anywhere from $5,000 to $35,000. Well, that’s quite a long shot, as the price of a 1.5-carat diamond depends on a couple of factors. Diamonds in fancy colors, such as red, will naturally cost more. So, if you’re looking for color diamonds, avoid fancy colors if you’re a little strapped for cash. It’s a tough balancing act though, considering fancy colors have impressive light-handling properties, hence create a better illusion of size. Therefore, while it’s the most expensive of all colored diamonds, choosing red color might save you the agony of going for more carat weight.

Still, on color, you might also consider going for transparent diamonds.  Colorless diamonds are as nearly expensive as red diamonds. That’s because of their rather minimal flaws. But since they reflect maximum color, they will help accentuate the size of your 1.5-carat diamond. For the best bargains, always consider shopping online from reputable dealers.

The question regarding the suitability of a 1.5-carat diamond isn’t one you can settle in one fell swoop. You have to carefully review how your decision affects the other elements – cut, color, and clarity. If you’re like most people, you desire a diamond that will stand out from your ring. As such, insist on fancy colors and cuts that feature elongated angles.
