Are any of your diamonds laser treated or modified in any way?
JamesAllen only sells diamonds that are 100% natural and untreated. The Gemological Institute of America (GIA), the American Gem Society Laboratory (AGSL), and the International Gemological Institute (IGI) will not issue grading reports on diamonds that have been treated or enhanced, so purchasing our diamonds - which are GIA, AGS or IGI certified - is another guarantee that your diamond is natural.

What does the term "eye clean" mean?
"Eye-Clean" is a term used to describe a diamond that is clean to an unaided eye in a face-up position from a distance of 8 to 10 inches. Diamonds of VS2 or higher in quality will always be eye-clean. Diamonds of Si1, Si2 and I1 need to be visually inspected to determine whether any inclusions are visible from the top. We can inspect any diamond at no charge.

What is "Cut"?
A diamond's cut determines how effectively it returns light to the viewer's eye: a well-cut diamond appears brilliant and fiery, while poorly cut stones look dark and lifeless. Well-cut diamonds often appear larger than stones of the same carat weight.

What kind of diamonds do you use for accent stones?
Smaller diamonds (often called melee) are cut in factories around the world and are available in a variety of qualities. The lowest quality goods are usually labeled as "commercial" and consist of I/J/K color and I1 clarity. "Promotional" goods are higher in both color and clarity, but are still cut for maximum weight. The highest quality diamonds are often referred to as "Collection". Collection diamonds are finer in both color and clarity. They're precisely cut to maximize fire and brilliance. Collection quality goods are only available from specialty dealers. We pride ourselves on using collection diamond melee in all of our engagement designs.

Are any of the gemstones used in your jewelry heat-treated?
Yes. It is very common for natural gemstones to be heated. Heating the stone can intensify color and clarity, making the gemstone more beautiful and valuable. In addition, emeralds are commonly infused with a colorless oil, wax or resin to improve their appearance and luster. Nearly all rubies and emeralds on the jewelry market today are heated or treated in some fashion.
