A Round or Brilliant Cut diamond is the most popular cut for your engagement ring for two reasons; it looks great on any hand shape, and when cut properly is the most sparkling of all diamond cuts. It is also the most expensive, due to the amount of diamond lost in cutting, and supply and demand. A Brilliant Cut diamond will be 25 – 35% higher in price than other diamond cuts.
Selecting a diamond for your engagement ring online can be challenging if you don’t have a few simple tips to help you choose the best diamond for your budget.
Carat: Carat is a weight. A one-carat diamond, depending on its cut, will have a range from approximately 6.1 to 6.5 MM's. Diamond prices rise exponentially once they reach the one-carat mark due to popularity and rarity. If you’re looking for a nice size stone at a lower price point search from .80 to .99 carats. They will range in MM size from 5.8 to 6.2.
Cut: The Cut is what makes the diamond sparkle. In searching for a Very Good or Excellent Cut diamond look for a Table and Depth between 58 and 60%. My preference is to get as close to a Table/Depth of 60-60% as possible, with a 1.00 to 1.01 Length to Width Ratio.
Color: Color-less is preferred and G is a good place to start. G is a warmer white while D is a cooler white. G through D are considered premium will command a higher price, with D as the most expensive color due to its rarity.
Clarity: The Clarity of a diamond refers to the visibility and number of inclusions in a diamond. Every person has a different level of tolerance when viewing a diamond with inclusions. All types of inclusions are not created equal, wisps and twine are thin and white so a few of these won't effect the over all appearance of the diamond. Clouds and carbon spots are more visible and if in the table they will greatly effect the quality of the diamond. Generally speaking start with a diamond with a GIA clarity grade of SI1, and look at the certification. SI1, VS1, VS2 and FL will have the best clarity.
Florescence: Is a natural soft glow or fluorescence in a diamond when it is exposed to ultra violet light like sunlight. A diamond with Fluorescence can appear one color grade lighter, making lower color graded diamonds with fluorescence cost more, while higher color grades (G, F, E and D) will cost up to 15% less because fluorescence is ultimately viewed as a flaw. However, fluorescence is a flaw most people will never notice so a diamond with a GIA grade of Faint to Medium Fluorescence can be a good value.
