Why are simulants important to the jewelry industry?
, Give this one a try later!
They can be manufactured in quantities and in nearly any size, which means
they're more plentiful, more readily available, and less expensive than
diamonds.
What is the formula for Total Depth Percentage for fancy shapes?
Give this one a try later!
Total Depth Percentage = (stone depth/stone width) X 100
What are advantages of simulants compared to diamonds and lab-grown diamonds?
Give this one a try later!
both readily available & much cheaper
How and why can a trained gemologist separate a synthetic moissanite from a
diamond?
Give this one a try later!
Because a diamond is singly refractive and synthetic moissanite is doubly
refractive, they only need to look for doubling of the facet junctions.
