At a point in nearly every man's life, there comes a  time when his heart knows it's time to buy a diamond engagement ring for  the woman he loves. Only then will you feel comfortable buying a  diamond engagement ring. There are many things to consider when learning  how to buy a diamond, you should never rush into buying a diamond  without first doing a little research as to how the diamonds are priced.  Buying a diamond is no different, except most of know us very little  about diamonds. Buying a 
diamond ring is often an emotional - not to  mention expensive - experience.

Diamond Ring:  
Buying a diamond ring can be a huge investment and you want to get  one with the perfect diamond in it, so you may be intimidated if you are  a first time buyer. Buying a diamond means investing in a piece for  forever. Every individual buying a diamond seeks out the best they can  afford. When buying a diamond, consider your budget and where the stone  will be worn to help determine the ideal carat size. The Four C's of  Buying a Diamond, to determine the best price for your ring, you need to  be familiar with the four C's. The four C's of cut, color, clarity, and  carat are explained.
Diamond Color 
Most diamonds have a slight hint of yellow and the diamond color  scale is based on the amount of yellow present in a diamond. It's the  absence of color that adds value to the diamond. Diamond color is graded  according to the GIA Grading Scale. Grades are based on the amount of  yellow that is visible when viewed face down through the pavilion using  the GIA Diamond Lite. The color scale ranges from D (colorless) to Z  (yellow tinge).
Diamond Cut 
To achieve the maximum reflection of light that causes a diamond to  sparkle requires a diamond to have an Ideal/Excellent cut grade. Ideal  cut diamonds are graded as such because they fall within the ideal cut  grade parameters specified by the diamond grading labs. The better cut  grades are likely to display more fire and brilliance and since their  appearance is more desirable, they are priced accordingly. The GIA and  EGL have only extended ideal/excellent cut grade parameters to round  brilliant stones at this time. Determining a diamond's cut grade,  however, goes beyond simple measurements of width and depth. Diamond Cut  is perhaps the most important of the four C's.
Diamond Clarity 
A diamond's clarity is determined by the number, nature, position,  size and color of internal characteristics called "inclusions" and  surface features called "blemishes". These show themselves as the  various characteristics which make up the clarity of a diamond, included  crystals, feathers, clouds etc. These characteristics are sometimes not  visible to the naked-eye and they are what make each diamond unique.  This clarity grade becomes more important as the diamond size increases.  The clarity scale was developed by the Gemological Institute of America  GIA to quantify these imperfections.
Diamond Carat 
It is a common misconception that carats refer to the size of a  diamond. In reality, a carat is the standard unit of weight by which  diamonds are measured.  Since a carat is a measure of weight, not size,  one diamond of the same carat weight may look bigger than another  depending on the cut. A premium cut diamond may actually appear bigger  than many diamonds of a higher carat weight.
Diamond Shape 
Stones come in different shapes - round, oval, marquise, pear, emerald, heart, princess, and radiant.
Round 
A round brilliant is a great choice if you want the most sparkle and  the most enduring classic shape round-brilliant diamonds are the only  shape to have this ideal proportion defined. Brilliant cut diamonds have  facets that are shaped like triangles and kites. Today's round  brilliant diamond has a total of fifty-eight facets, but you'll see  varying facet numbers in vintage brilliant cut diamonds. Even though  Round Brilliant cut diamonds are the most expensive in the market, they  make up the overwhelming majority of diamonds found in engagement rings,  and are popular as stud earrings and pendants.
Oval   
The elongated shape of Oval diamonds gives a very flattering effect  to your finger when worn in a ring, and is found in some of the most  beautiful diamond engagement rings. Unlike round cut diamonds, oval cut  diamonds have an elongated shape, which makes the diamond appear larger  in carat weight. Oval cut diamonds are essentially elongated round cut  diamonds. Many women with smaller hands or shorter fingers prefer the  look of oval cut diamonds and pear shaped diamonds because they truly  slenderize and elongate the fingers on the hand.
Marquise   
While marquise diamonds are not as popular as round cut diamonds or  princess cut diamonds, they are still quite sophisticated and elegant. A  marquise cut diamond has a uniquely beautiful shape that is favoured by  many women, but a small percentage of brilliance will be sacrificed for  the beauty of this uniquely diamond shape. Compared to the round cuts,  the marquise diamonds are not as popular these days. In addition, the  shape of the marquise diamond almost makes the stone appear larger than  it is. The Marquise shape was created for Louis the XIV and is has  become a timeless classic.
Pear 
The pear shape is a stunningly feminine diamond shape with a rounded  end on one side and a tapering point at the other.  Due to their  elongated shape, pear cut diamonds are known for their slenderizing  effect. .The Pear cut allows a range of cutting styles, so that the  teardrop shape can be wider, slimmer, or cut to Ideal proportions, based  on your choice and preferences. Pear shaped diamonds have a rounded end  and a single point. While pear shaped diamonds are not as traditional  as round cut diamonds, or as trendy as princess cut diamonds, they are  still coveted by many people.
Emerald 
The emerald-cut diamond is among the most classic of diamond shapes  that is distinguished by beveled corners and step facets, emerald cut  diamonds are more transparent than other shapes, resulting in the need  for higher standards of clarity. The emerald cut can be one of the least  expensive to cut because its shape is most like the natural shape of  the rough diamond crystal. Because of the angle, size and shape of the  facets, the emerald cut shows less brilliance and fire dispersion than  the other brilliant cut diamonds. However, the emerald cut stone reveals  a classic beauty and elegance not seen in other cuts. The trim lines of  Emerald cut diamonds lend an elegant, sophisticated air to both the  simplest of ring designs.
Heart 
The heart-shaped diamond is the most romantic of diamond shapes and a  symbol of love and affection, the heart cut diamond is an excellent  choice for an anniversary or engagement ring. It is a tender gesture to  make to someone special. A quality heart-shaped diamond is lovely and  distinctive, with an even shape and well-defined outline. They are the  ultimate symbol of romance, and more and more people are choosing heart  cut diamonds for engagement and anniversary rings. Heart Shaped Diamonds  are rarer and more expensive as it takes a large piece of diamond rough  to shape cut and polish to something that is the ultimate symbol of  love "the heart"
Princess  
A modern innovation, the princess shape dazzles and sparkles with  its star burst facet pattern, while still leaving the crown of the  diamond flat and open. The princess cut is stunning set as a solitaire  it is a modern classic of clean, square lines and beautiful sparkle. Its  sharp corners are usually contained in a four-pronged or bezel set in  wedding rings. You will also find Princess cut diamonds are often  channeled into the wedding band itself. Princess Cut Diamonds are for  those people who love the sparkle and brilliance associated with round  cut diamonds, but prefer  the shape of a square. While the round  brilliant solitaire seems to be the most popular shape right now for  engagement rings, many people are deviating from this trend and going  with princess cut diamonds.
Radiant 
The radiant cut was first patented in the late 1970's by  Henry Grossbard, with its angular shape and brilliant cut facets it  makes a scintillating alternative to other cuts such as the Emerald cut.  The radiant shaped diamond can be considered a modified brilliant  diamond that is closely related to the princess cut diamond because of  its square shape. High quality Radiant cut diamonds combine the fire and  sparkle of Emerald and Round cuts.
Now you know the different  shapes of diamonds that you can purchase and which shape will accentuate  individual fingers or provide brilliant sparkle we can now move on to  the ring.
There are many different metals used for rings today  which can be grouped into two, precious and non -precious, those in the  precious group including silver, gold, and platinum, while those in the  non-precious group can include brass, copper ad nickel. Most rings today  are made of gold or platinum so we will focus our discussion on these  two precious metals.
Gold   
Gold comes in various colors that can reflect the carat value of the  carat of yellow gold with 10k, 14k and  18k being the most popular. Did  you know that you can get Rose Gold, white gold and yellow gold and  that white gold is more a silver color than white? Until recently white  gold was yellow gold with as much of the yellow gold removed as  possible, however it was still not a true white color. To give you that  white (silver) brilliance the rings are plated with Rhodium or  palladium.
Platinum 
Platinum became very popular for its natural white (silver) color  and durability. Customers that buy white gold rings that have rhodium  plating will have to have the ring re-plated every few years if it's  worn regularly,  as the rhodium wears off. With platinum the color stays  the same no mater how often you wear it. Platinum is about twice the  price of 14K Gold and can push the price of the setting and diamond out  of the range of some customers.
Ring Mounts 
There are thousands of different settings available for you to  choose from; they come in all shapes and sizes, from solitaires to multi  stone rings. Your choice is a personal one; however you should consider  when you are going to be wearing your ring. If you plan to wear it  daily then pick something with a low profile that protects the diamond  and setting from getting damaged if you accidentally catch it against  something. This could lead to the diamond coming loose and having to be  reset, to forcing the diamond out of the mounting and breaking it.
On  the other hand,  if you are only going to wear the ring for special  occasions then purchase a mount that holds the diamond high so that it's  well displayed and allow the light to enter unobstructed from the top  and show the scintillating fire and brilliance.
Remember that if  you are purchasing a high quality diamond for your ring that having  other diamonds around it will detract from your central diamond. If on  the other hand you are purchasing a smaller center diamond adding  smaller ones around the outside will make the center one look larger.
Engagement  sets are also very popular, with couples purchasing the engagement ring  and then going back and purchasing the wedding band from the set, for  that special day.
