I have actually a just recently evaluated custom ring in yellow 14KT gold with 5 diamonds cast in a flower pattern. The appraisal from a Graduate Gemologist and Sr. Member of The National Association of Jewelry Appraisers was available in at $2,475 US. Per the appraisal, the total weight of the diamonds is 0.90 ct. and complete weight of the ring is 4.50 gm.
