Why Buy Diamonds Online?
Purchasing a diamond or buying diamond engagement ring can be a daunting task. For most people it can be down right nerve racking. For this reason it is important to buy your diamond ring at a jeweler you can be comfortable and at ease with. Here we will share with you how to buy a diamond online.
Ideally you should go somewhere quiet, calm, trustworthy and a great inventory / variety of diamonds to buy a diamond. If you have a diamond jeweler near home that you are very familiar and comfortable with then he can be a great option. However most people do not have the pleasure of sharing a friendly relationship with a diamond jeweler.

A jeweler, unlike a regular sales person will be knowledgeable enough to really help you through the jungle of diamond cuts clarity, color and the diamond shapes and designs. Unfortunately a knowledgeable diamond jeweler is a rare occurrence so most of what people get is a pushy salesman at their local mall jewelry store. He may want to hurry you into a quick decision or there could be others watching you strain on deciding on which setting or diamond to buy. That can be tremendously discomforting. You owe it to yourself and future fiancee to buy the diamond engagement ring (diamond and ring setting included) properly and without additional pressure.
Additionally you want to avoid the person who gets paid on commission because they may be offering you a diamond that may not be in your best interest but will be for their interest. A local jewelry store inventories of diamonds or variety of diamond shapes and diamond grades may also be limited. I went through all these trials and tribulations. This is when I started looking for online diamond retailers.

If you don’t have a diamond jeweler to buy a diamond that you trust and are comfortable with a great option for buying the diamond engagement ring can be through an online diamond retailer.

Once we have covered the main shapes as well as a few others you probably will have warmed up to a shape that will suit your fiancees taste and hand.
Below you will find descriptions of the variety of shapes.
Round Brilliant Diamonds
The Round Brilliant cut of diamond has lately become the default diamond shape that has been chosen for a diamond engagement ring. Due to its design in proportions and high number of facets (58) it achieves the unsurpassed brilliance and fire. Hence the round brilliant cut is chosen 7.5 times out of 10 when choosing loose diamonds.
This round cut is simply the most popular cut that is requested. It is preferred over 70% of the time when picking a diamond shape for her diamond engagement ring. Because demand is so strong for the round brilliant it is also the most valuable.
There is a reason for this. It is hands down the diamond cut with the most fire and brilliance due to its numerous (57-58) facets that force the light to reflect from many angles inside the diamond and back at the viewer. There are other diamond shapes with more facets but generally they are hybrids of the round brilliant diamond or a variation of a rectangular / square diamond that needs this many facets to be able to compete with the fire and brilliance of a round diamond cut.
Mounted, a round brilliant diamond ring will look dazzling in almost any setting and lends itself to many creative options from simple solitaire and solitaires with accents to the most contemporary of settings, the tension setting. Round cut diamonds excel beautifully in all these circumstances. In most instances when choosing a setting try to find one that allows for the most light to shine upon it. This will help maximize the fire and brilliance it was designed for.

Oval Diamonds
The Oval cut is a design that is very well suited for women with smaller hands and fingers. Due to its oval symmetry it gives the illusion of elongating the wearers hands. Ideally should be used in a solitaire setting.
Oval cut diamonds have all the benefits of the round brilliant diamond but are Blessed with an elongated shape that is best suited for long, elegant hands. Although there is a slight difference between round brilliants and the oval cut diamond they share a high amount of facets that offer great brilliance.
Although it is well suited for small hands an oval diamond can be used for anyone who simply wants something different and unique than the regular round brilliant.
When choosing a setting for an oval diamond usually a setting with accents to its sides or as a cluster surrounded by accents is what may best suit this diamond cut. In addition make sure that the setting has six prongs to anchor the oval diamond. An oval diamond ring must have these additional prongs due to the shape of the diamond and the difficulty to hold the oval diamond in place.
Oval or oblong shaped diamonds can suffer from what is called the bow tie effect diamond cutters jargon. This refers to a diamond that is not well cut and shows a dark bow-tie like shape in the middle. Almost like and empty, life less section in the center of the Oval diamond.
For ideas on how to mount an oval cut diamond view the ring trends page or use the design your own ring tool available at JamesAllen.com, and Blue Nile (Our Editors Top Tier Online Jewelers). View our Online Jeweler Review section for other great online diamond jewelers.
Buy an oval cut diamond if you want the benefits and beauty of the round brilliant but would like the original shape of the oval cut.
Marquise Diamonds
Marquise diamonds, similar to the oval also are well suited for women with smaller hands and fingers. The difference with the Marquise is in the points at the extremities. This design was originally created to emulate the charming smile of the Marquise de Pompadour and hence the name Marquise. This diamond shape should also be used in a solitaire setting so as to not bulk up a small hand.
Pear Shaped Diamonds
Similar to a tear drop, The Pear Shape Diamond takes the best characteristics from both the Marquise and the oval. It is usually used for pendants or seen on dazzling dangling earrings but can also be used for a diamond engagement ring. It is also suited for smaller hands and fingers.
The Pear Shaped Diamond is an hybrid between the oval and marquise cut diamond. However the term that best describes the pear diamond cut would be tear drop.
Drawing similarities from two wonderfully brilliant diamond cuts, the pear shaped diamond doesn’t fall far from these. Having sparkle and the uniqueness of being a shape that is rare could be an enticing option of originality to combine into a pear diamond ring.
In choosing a diamond ring setting for a pear shaped diamond be sure to use one with 5-6prongs. The absolutely critical prong for a pear shaped diamond is the one that protects the point of the diamond. The additional pronge also serves as protection to the point of pear diamonds. See the pear shaped engagement ring to the right for an example of what I am referring to.
As discussed with the marquise cut diamond, the pear shaped diamond is also susceptible to the bow tie effect if not cut properly. The bow tie effect is when a portion of the diamond is cut in such a way that the facets don’t reflect properly enough to illuminate a bow tie shaped portion in the center of the loose pear shaped diamond. You do not need to worry too much about a bow tie sneaking on to your mount as it is a very visibly evident aspect.
Other very popular uses for the Pear diamond other than a pear diamond engagement ring is as pear diamond pendant or pear diamond earring.
Heart Shaped Diamonds
A heart Shaped diamond is a very rare cut and therefore is usually very difficult to find. This is mainly due to the difficulty in creating such a beauty. The heart shaped diamond is usually used for emotional or sentimental purposes other than a diamond wedding ring. Be certain to inspect this one for uniformity and well defined borders.
The Heart Shaped Diamond is a very unique diamond shape. If there is one way to really draw attention to a diamond ring it is with a fancy cut heart shaped diamond. The heart is a symbol of love and romance in any culture and giving it in the form of a heart shaped diamond would be unforgettable. As far as fancy cut diamonds go this is about as unique and original as it gets. Since it is a contemporary cut, the Heart Shaped Diamond was designed to have a lot of brilliance. Designed with the round brilliant diamond in mind to get as much brilliance out of a heart shape. With 59 facets you are getting a lot of fire and brilliance and will suit many uses. In many cases a diamond cutter takes diamond stone with a large inclusion and whittles away to eliminate the inclusion creating the cleft of the heart.
While the heart shaped diamond will look great on as a heart shaped diamond ring it can play a romantic role as a heart shaped diamond necklace or as heart shaped diamond earrings. Frequently you will see 2 carat heart shaped diamonds used for a necklace or a pair of 1 carat heart shaped diamonds used for earrings.
In the case of a heart shaped diamond it is important to review the overall quality of the diamond, including diamond color cut clarity and carat weight. I do suggest that you review proportions closely to make sure your diamond has great brilliance and fire. The proper depth of the diamond will give you optimal light reflection giving you all the sparkle that a heart shaped diamond ring deserves.

Emerald Cut Diamond
The rectangular shape used to cut most emeralds is what gives this diamond shape its name.

This places a premium on superior clarity grades as inclusions become more visible. An emerald cut is considered a very traditional and elegant cut.
The Emerald Cut Diamond is one of the classiest diamond shapes you can buy. It is a step cut square or rectangular diamond with the corners cut. The name originates for the way that emerald are cut. Since emeralds tend to have more inclusions their resistance to breakage is greater. Thus the emerald cut was designed to minimize the quantity of cuts to prevent a breakage of the emerald.
By step cut I am referring to the technique that the cutter employs to give the emerald cut its long lines. The step cuts are actually large stair-like facets that give the air of class and elegance to a great Emerald Cut Diamond. The cut off corners allow for more light to reflect inward as well as frame the beauty within the diamond stone.
The emerald shape diamond was been worn for centuries by royalty and the upper class. An emerald shape diamond is often times in fancy colored diamonds or gemstones to really show off the quality of spectacular loose diamond. This type of diamond cut has also been seen pendants.
