What is 'Sparkle'?
What we know as 'sparkle' is a combination of three types of reflection, which occurs both in natural diamonds and in lab grown diamonds, these three types of sparkle are referred to as brilliance, fire and scintillation.
Occurs when light enters the lab grown diamond and is reflected out of its table. This is the white flashes of light that you see in the sparkle of a diamond.
Occurs when light hits the diamond and is dispersed causing it to split into each individual wavelength which created white light, creating a rainbow like effect in the sparkle of the diamond.
Is visible as flashes of light which can be seen when the diamond is moved.
An ideal cut grade is rare, the diamond has been polished to near perfect proportions giving it the best ability to reflect & refract light. A diamond with an ideal cut grade will be more expensive than those of lower grades.
Excellent cut diamonds are very nicely polished but will reflect light slightly less effectively than an ideal cut diamond.
A very good cut grade is acceptable and will reflect the majority of the light that enters it. This cut grade is less desirable than an excellent or ideal cut grade and therefore will be less expensive.
A diamond with a good cut grade will not have as much brilliance, fire or scintillation than those with higher cut grade, but still have some sparkle and can make very nice diamonds.Due to our tight regulations on diamond quality, we only stock diamonds of a good cut grade or above.
