Here you’ll find some simple guidelines to follow to purchase on the internet the most popular diamond shape. The ROUND BRILLIANT DIAMOND!
1- DECIDE YOUR BUDJET
Have a reasonable idea of what diamond color and carat weight you are looking for. Colorless diamonds (D, E, and F) will cost more. Near-colorless diamonds (G, H, I, and J) are more economical.
2- LOOK FOR DIAMONDS THAT ONLY HAVE THE HIGHEST CUT GRADES (GIA Certification is excellent)
Since cut is the most important characteristic when it comes to a diamond’s brilliance and sparkle, you don’t want to compromise in this area. Cut is a somewhat complex characteristic to evaluate.
For round brilliant diamonds, look for the following dimensions: Table % = 52.4% to 57.5%, Depth % = 58.7% to 62.3%, Crown Angle = 33.7 to 35.8 degrees, Pavilion Angle = 40.5 to 41.0 degrees.
3- ENSURE THAT YOUR DIAMOND HAS NOT VISIBLE INCLUSIONS
Remember that natural diamonds are 1-3 billion years old and were formed originally deep within the Earth’s mantle. Through extreme heat and pressure they gained their durability and hardness. Inclusions are a natural by-product of this natural process and shouldn’t be unexpected.
Clarity does not equal brilliance. A diamond’s ability to reflect light from within its facets is indicative of its cut – so be sure to focus on cut quality above anything else.
4- CONSIDER A DIAMOND’S FLUORESCENCE
In some cases for diamonds that are colorless (D-F), a strong blue fluorescence can sometimes make the diamond appear “milky” or even cloudy. In other situations, near-colorless (G-J) and tinted (K-M) diamonds can actually benefit from the strong blue fluorescence because the natural yellow tint that they have can be cancelled out by the blue hue.
In both cases, it is important to see actual pictures of the strong blue fluorescent diamond to ensure that it is not negatively affected by the fluorescence.
Good luck for your research!
