step 1Choosing a diamond’s shape is extremely important. Why? You are not the one wearing the ring or earrings!

Your partner will likely have saved pictures on their Pinterest or phone and pictures help but seeing a diamond in person can easily alter the desired shape.

Your very first action should be to casually take your partner to a jeweler and view different diamond shapes. If you are in the shopping mall, for example, just casually walkthrough and get your partner to react to the diamonds you are viewing. You can even achieve this at your local Costco!

Once you know the shape your partner wants, focus only on that shape. Most online diamond vendors allow you to choose multiple shapes during the search process. We do not find that beneficial. Focus on one shape at a time!

Start with the center stone. If you are searching for side stones for a three-stone ring or multiple stone earring, it is very easy to find matching diamonds with patience. Do not let a Jeweler convince you otherwise. The Jeweler will save you the time and energy, but not the cost.

The Round-shaped diamond is by far the most popular cut diamond, and due to this, it’s often higher in cost per carat than the other shapes.

When selecting a Round-shaped diamond, it is very important to focus on the diamond’s cut grade. The better the cut grade, the greater the sparkle and round cut diamonds are known for having the most brilliant sparkle. The cut grade for a Round Cut diamond should be excellent if not, it can lead to purchasing a diamond with a dull appearance and lack of sparkle. The cut is not the place to sacrifice when searching for a Round Cut diamond. If your budget is restricted, the best areas to sacrifice on quality are Color and Clarity. A Round-shaped diamond hides its color and inclusions very well, so play around with your selected filter settings.

The ideal length to width ratio for a Round-shaped diamond is 1.0 to 1.03.


The Cushion-shaped diamond is a great alternative if your loved one is not a fan of the Princess-Cut. This diamond’s shape best resembles a pillow and is a more classic, softer appearance on the eye thanks to the rounded edges.

The Cushion-cut comes with multiple cut options and can only be decided by personal preference. If you are searching for a flexible diamond that provides a classic and modern style, this diamond-cut may be the one for you.

The ideal length to width ration for a Cushion-shaped diamond is 1.0 to 1.09. If you prefer a slightly more rectangular-shaped Cushion-Cut, then make sure to choose a diamond with a ration about 1.10.

Table and Depth are important sparkle factors. The relationship between the two impacts how light reflects and passes through the diamond, and for this diamond shape we prefer both to be under 70%.


This diamond is one of our favorites! The beauty behind the oval-cut diamond is its illusion. Its shape lends to making your partner's fingers appear skinnier and longer. The oval-shape will appear larger than a round-shaped diamond at a smaller carat weight, and this diamond makes for a beautiful three-stone ring.

Oval diamonds come with the black bow-tie effect; the result of light passing through the diamond. This is something you cannot remove, but you can reduce its effects. To do so, you want to focus on the symmetry, table, and depth.

Symmetry is most important with oval-cut diamonds and need to be excellent.

Table and depth play a factor in the bow-tie effect by helping the diamond reflect light. We prefer the percentages for the table to be 53% to 63%, and depth 58% to 62%.

The ideal length to width ratio for an oval-cut diamond is 1.3 to 1.4. Ratios greater than 1.5 will result in a longer oval.


These diamonds are beautiful, flexible, and a better value than the round-cut diamonds. This makes the princess-cut diamond one of the more popular choices for buyers. Why is the princess-cut valued less than the round-cut? It is due to the high effciency and little waste produced when forming the diamond from its octahedron rough stone. This allows diamond cutters to produce two similar princess-cut diamonds from the same stone. The higher effciency equals the lower cost to you.

If you are looking for the biggest value with your budget, then the princess-cut is a diamond you want to focus on. It is the cheapest per carat diamond of all the fancy-shaped diamonds.

One of the things buyers tend to overlook is the points on the diamonds. Here, the princess-cut diamond has four corners and these corners will need to be protected. So, when you are setting your diamond, make sure the Jeweler applies prongs at all four corners of the diamond. This is very important.

The ideal length to width ratio for a princess-cut diamond is 1.0 to 1.05.

*When buying loose diamonds online, ALWAYS review the GIA certification AND ask the Seller for imagery and a video of the diamond. If the Seller cannot provide these things, then move on. Never purchase a diamond if the GIA number is blocked-out/hidden on the certification. The information provided above should be use for reference only.


Elegance and class are two words that describe this glassy diamond. Known for its step cuts, the Emerald provides a larger looking diamond with beautiful reflections for a great value and a discounted price from the Round-cut diamond.

The Emerald-cut comes with a higher surface area than other diamond cuts, resulting in a few diffculties. First, the glassy appearance plus the greater surface area make the Emerald-cut more susceptible to inclusions. Where in many other diamonds you can lower the quality to the SI range, the Emerald you will want to keep a higher clarity. We recommend the VS range or higher. Thanks to our loose diamond search tool, you should be able to get clarity within the VVS range that meets your budget.

Second, the color. You will want to remain at a grade G or higher. This, again, is a result of the larger surface area, or table.

Emerald-shaped diamonds can come in a square form, but we prefer the classic rectangle and recommend a length to width ratio of 1.4 to 1.6.

Lastly, make sure to focus on the Emerald’s cut grade.


The Radiant-cut diamond is the result of combining the Round-cut and Emerald-cut diamonds. This beautiful diamond provides an amazing sparkle - the amount of light reflected. Its closest diamond relative is the Cushion-cut diamond, with the major difference being beveled corners versus the more rounded corners of the Cushion-cut. Unlike the Princess-cut diamond, the Radiant-cut has no pointed corners making this diamond the better choice is you are afraid of breakage.

A Radiant diamond will not come with a cut grade; therefore, to maximize the sparkle you should focus on the diamond’s symmetry. We always recommend an excellent symmetry for fancy-shaped diamonds.

Our preferred length to width ratio for the Radiant-cut diamond is 1.0 to 1.3. If you prefer a squarer Radiant-shaped diamond, then you will keep the ratio closer to 1.0.

Due to its sparkle, you can choose a color diamond grade off H or higher.


We love this diamond-cut and that is why we modeled our logo after the pear-shaped diamond, also known as a teardrop. These diamonds make for beautiful solitaires, side stones for a three-stone ring, or can be wrapped with a halo.

The Pear-cut is a fancy-shaped diamond, so you need to focus on its symmetry. We highly recommend an excellent symmetry for maximum sparkle and a color grade G or higher. Some experts will advise a grade H, but we prefer a G.

It is very important to protect the Pear-cut diamond’s point with properly placed prongs.

The Pear-cut diamond has the same concerns as the Oval-cut. If you are not careful when viewing the diamond, it can come with a black bowtie. Always review a 360-degree video and pictures.

We prefer a length to width ratio of around 1.6, plus or minus .05.

If you are in the market for earrings, we highly recommend the Pear-cut diamond for studs.


Like the Emerald-cut diamond, the Asscher-cut comes with larger step cuts, a smaller surface area (table), and is square-shaped. This cut, like the Emerald, is susceptible to inclusions, so you will want to stay within the VS clarity grades or higher.

We recommend a length to width ratio of 1.0 to 1.05. This ensures you are getting a beautiful square diamond.

If cost is a concern, you can choose an Asscher-cut diamond with as low as an I or H color grade.

The Asscher-cut comes in two styles: The Royal and the Standard. The difference between the two is the number of facets. The Royal style has 74 facets, while the standard has 58 facets.

Like the Oval-cut diamond, the Marquise-cut is the best for overall size to the naked eye. You can purchase a smaller carat Marquise-cut and it will appear visually similar to larger carat cuts. This diamond-cut will make your partner’s fingers appear longer and skinnier, just like the Oval-cut does.

The Marquise-cut diamond was meant to resemble a mouth, but most people see a football or the shape of an eye.

When purchasing this cut, you must protect the pointed ends with properly placed prongs. Not doing so will result in chipping/breakage.

The Marquise-cut can be plagued with the bow-tie effect. You must review a 360-video and as many pictures as possible when buying online.

Focus on the symmetry to get the best possible sparkle.

We prefer a length to width ratio of 1.9 to 2.05.


If you are looking for a diamond that shows your love, you cannot go wrong with the Heart-cut diamond. We do recommend using this cut for a center stone and stay around the 1-carat size dimensions or higher.

Length to width ratio is very important for this cut. We recommend a length to width ratio of 1.0 or slightly over. Nothing above 1.08, otherwise the Heart-shaped diamond can appear stretched or squished if the ratio dips under 1.0.

The Heart-cut comes with a point. You will need to protect the pointed end with a properly placed prong.

Like the other fancy-shaped diamonds, the Heart-cut needs an excellent symmetry to maximize the appearance and sparkle.
