Melee Diamond Sorting
At K. Rosengart, we pride ourselves on having the most precise loose diamond sorting
process in the industry. Our team of GIA graduate gemologists follow GIA’s strict standards
of diamond grading when it comes to the 4C’s.
Every single diamond in your order will meet your needs and specifications. Our inventory is
sorted by size (within .05mm tolerance). We carry three color categories: G+, H, I/J. Within
each color we offer multiple clarity options.
