Heart Shaped Diamond Pendant Necklaces | Rare Carat

Hello people of the internet! If you happen to be in the market for a heart shaped diamond pendant necklace, then today is your lucky day! I will lay out all the things to consider when buying such a dazzling gift - including features, quality, and design elements. As a true lover of all diamonds, I am here to support you on your heart shaped diamond jewelry journey!

Things to consider when buying a heart shaped diamond necklace:

Proportions & Symmetry:

This is one of the most important aspects of a pretty looking heart! Proper balance of a heart would show even lobes, it won’t look too long or too short, and the heart should have an overall matching of both sides if it were split right down the middle. And, because hearts come in many variations, if you buy heart stud earrings be sure you check that both hearts look similar!

The quality of a diamond is always important, no matter what shape it is. The price of the diamond will consistently reflect the quality, so it is good to know what you are looking for beforehand! The 4C’s is what establishes the quality of every diamond: cut, color, clarity, and carat weight.

  • Cut: The cut of the diamond is how well the rough diamond was cut into the beautifully finished diamond that it is (not to be confused with the shape of the diamond). This scale ranges from excellent to poor. For hearts specifically, the cut grade will be based largely on the symmetry and proportions of the diamond - so be on the lookout for a stone with an excellent or very good cut grade. For a quick way to get the best cut heart shaped diamond, be sure to set the cut grade filter to Rare Carat Ideal on our search page.

  • Color: Our colorless diamond grading scale ranges from D to Z, or from colorless to noticeably brown or yellow tinted. True colorless diamonds are rare (most will have some kind of a yellow or brown hue) - so these tend to be more expensive. Finding a diamond that falls into the grading span of D to K will give you a range in price points for diamonds that are colorless or at least appear to be colorless.

  • Clarity: Clarity is the heavy-hitter when it comes to the price of a diamond. This grading scale ranges from flawless to heavily included, with flawless diamonds being very, very rare. The sweet spot for budget purposes will be within the SI range. Look for eye clean SI1 diamonds in particular - these will be flawless looking diamonds (on a non-microscopic level) for SI grade prices. They do exist I promise!

  • Carat Weight: This one is probably obvious but the bigger the diamond, the rarer it is, and the more it will be worth. All sizes are beautiful! …but I do love an extra big stone…


When we are looking at such a simple piece of jewelry, every detail matters. The shape of the heart, the setting of the necklace, and the metals used are the most important features for a heart shaped diamond pendant necklace.

A setting is what holds the diamond in place for our necklace. We have 3 commonly used settings to choose from here - prong, bezel, and halo. And each one of these creates its own distinctive look.

  1. Prong: This setting is the simplest; the diamond sits securely in a small metal claw which has little metal prongs that come up and over the diamond, allowing the sides of the stone to be open. This lets the most amount of light to reach the stone, which means it is the best setting for maximum sparkle!

  2. Bezel: A bezel setting will surround the diamond with metal, leaving a little metal rim around the top of the stone. This is one of the most secure settings because of how the stone is being protected all the way around. But because the metal covers a lot of the diamond, it won’t be able to sparkle quite as much as a diamond in a prong would.

  3. Halo: Yes! Even heart shaped diamonds can have halos. Halo settings will protect the center stone, enhance the overall size of the heart pendant, and it will create extra sparkle for those who love a good bling moment. This setting is a great way to add tons of interest to the simple design aesthetic of a pendant.

Metal Option:

The metal choice is important because some metals are softer and scratch easier than others, but also (and more importantly) this choice will dictate what color your necklace will be! The most popular options are platinum, yellow gold, white gold, and occasionally rose gold will make an appearance… but basically this is just a personal preference decision. Whatever you like is perfect!


Does gifting someone a diamond heart pendant necklace mean something? Short answer - not necessarily. Longer answer - yeah probably; I mean hearts are basically the international sign of love, and diamonds “are forever”…. so it seems to me that if a heart shaped diamond necklace were to mean anything, “I will love you forever” seems to be a safe assumption. But, it only means something if you want it to mean something, no matter how obvious the symbolism is!

Heart shaped diamond pendant necklaces are simple, cute, and a potentially meaningful gift. Extra points for using Valentine’s Day or a big anniversary as an excuse to present such a fun shaped gemstone to someone. And, since you now know what diamond quality to look for, and the design elements to consider, you are ready to begin the official hunt for that perfect heart shaped necklace! Good luck!
