Ideal Cuts

1.5 lies midway between 1 and 2. Customers who prefer the stone’s invincibility would purchase 1.0 carats when shopping for diamonds. 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&nbsp;<a href="https://www.petragems.com/blog/how-much-does-a-2-carat-diamond-cost/">2 carat diamond</a>,
 obviously subject to all the remaining constant factors.<a href="https://www.jamesallen.com/loose-diamonds/all-diamonds/?a_aid=5c83f22427304" target="_blank"><img loading="lazy" class="img-responsive" src="https://backend.petragems.com/public/api/Images/img-1687674586.webp" alt="James Allen Diamonds" width="379" title="James Allen" height="212"></a>

The illustration above shows that 1.5 carat diamonds enable
 you to enjoy the best of both worlds. You end up with a stone small enough to
 retain its chic appearance and big enough to be eye-catching. If you are
 fortunate, you may come across a 1.5 carat diamond 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 carat is the
 ideal diamond weight.

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

First, you need to settle on your preferred color, cut, and
 clarity, which we believe you have already taken care of. 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 that you should establish is
 whether you are comfortable with the size. And as you know, size can be pretty
 relative—what works for you might not work for the lady next door.<img loading="lazy" class="img-responsive" src="https://backend.petragems.com/public/api/Images/img-1687764228.webp" alt="1.5 carat diamond actual size" width="690px" height="324px" title="Carat size chart">

Why A 1.5 Carat Diamond

A 1.5-carat diamond has a diameter of 7.4 mm. This is 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, roughly 18% smaller than 2 carat diamonds. Thus, everything
 considered, a 1.5-carat diamond is outstanding. It can stand out better
 depending on the wearer's hand and the ring on which it is set. The smaller the
 hand or ring, the more prominent the diamond.

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 is not unusual to come across a 1-carat diamond that looks
 larger than a 1.5 carat stone, nor is it surprising to find a 2-carat diamond
 looking significantly smaller than a 1.5 carat diamond.

A&nbsp;<a href="https://www.petragems.com/education/diamond-cut/">diamond cut</a>&nbsp;is the most critical element of the
 Four Cs that influences 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.

 Besides 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 if other factors are kept constant, a
 1.5-carat diamond will likely give more sparkle than a 1-carat diamond. The
 fire and brilliance of a 1.5-carat stone will also depend on the ring’s color
 on which it is set. 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 recommend going for the color H and a clarity of VS2.

The Asscher and Emerald cuts are the most sensitive shapes regarding
 color-handling properties. As these shapes feature large windows that stretch
 into the depth of the diamond, they will reveal even the slightest color hues
 and imperfections. While 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. Clarity 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. Consequently, you must always go for transparent, eye-clean diamonds.

Lastly, if you wish to enhance the size of your 1.5 carat
 diamond, find a decent setting for it. The halo setting is one of the top
 recommendations here. It features small diamonds surrounding the center stone.
 Anyone looking from afar would think that it is one large stone. 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 Big Is A 1.5 Carat Diamond?

Please refer to our <a href="https://www.petragems.com/diamond-prices/" class="external">diamond prices charts</a> for reference. It can range anywhere from $5,000 to $35,000. This is 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 are looking for colored diamonds, avoid fancy colors when strapped for
 cash. It is a tough balancing act because fancy colors have impressive
 light-handling properties and create a better illusion of size. Therefore,
 while it is the most expensive of all colored diamonds, choosing red might save
 you the agony of gaining more carat weight.

As for the color, consider going for transparent
 diamonds.&nbsp;<a href="https://www.petragems.com/education/colorless-diamonds-d-e-f-color/">Colorless diamonds</a>&nbsp;are
 nearly as expensive as red diamonds because of their 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 differs from one you can settle in at once. You must carefully review
 how your decision affects the other elements—cut, color, and clarity. Likec
 most people, you will desire a diamond that stands out from your ring.
 Therefore, you must insist on fancy colors and cuts with elongated angles.
