It’s a good idea to think about your budget before you start shopping online or meet with one of our diamond experts because it helps narrow your focus.

Fortunately, there are beautiful engagement rings and wedding rings for every price point. No matter your budget, you can have a beautiful and timeless engagement ring.

Diamond Shapes

Before making any decisions about diamonds or engagement rings, you’ll need to pick a diamond shape. If you’re buying the ring as a surprise, you may ask your partner’s friends what type of diamond shape they like. If it’s not a surprise, you could ask your partner to show you pictures of what they want — or have them bring the pictures into a Helzberg Diamonds store.


  • Round – The traditional and most popular (not to mention symmetrical) diamond shape. It’s round. A perfect circle. The round brilliant diamond is the most popular.

  • Radiant – A square shape similar to the emerald cut with a brilliant-cut facet pattern.

  • Heart – A diamond shaped as a heart.

The Four C’s and What They Mean for You


The most important of the four C’s is cut. The cut of a diamond affects how well a diamond returns light back to the viewer's eye, so this is what makes it sparkle. A diamond’s cut creates its brilliance, fire, and scintillation, can hide inclusions (small internal flaws in the diamond), and can even make a diamond seem whiter.


Diamond color actually measures the lack of color of a diamond. The less color in a diamond, the higher its value. The Gemological Institute of America (GIA) grades diamond color on a scale from D (colorless) to Z (light yellow or brown). The highest quality diamonds are colorless — their grade will be D through F.


Clarity is the measurement of minor imperfections on and inside a diamond. The surface flaws are called blemishes, and internal defects are known as inclusions. These natural imperfections are microscopic and do not impact a diamond’s beauty, but the fewer imperfections a diamond has, the better grade it will get. 

Carat Weight 

A diamond’s carat weight is the weight of the diamond in carats (simple enough, right?). One carat = 0.200 gram. Carat is not the visible size of a diamond, and how big a diamond looks is also impacted by cut and the engagement ring style. Diamonds with a larger carat weight are exponentially rarer, and the diamond’s value increases exponentially with it.

 The value of the style is all personal, and there are plenty to choose from. Talk to your partner about what they like, shop together, or do some investigating with friends and family if it’s a surprise.

After all your choices are made, look at the final details of the engagement ring and if you need to, design your own. Helzberg Diamonds offers all different types of ring settings, diamond shapes, and carat sizes to choose from.
