GIA Certified Diamonds

Find the perfect diamond for the perfect engagement ring! At Schwanke-Kasten Jewelers, in Milwaukee, Wisconsin, we offer competitively priced diamonds that are guaranteed to be independently certified by GIA for quality and beauty.

We highly recommend exploring natural diamonds with GIA certifications

The GIA is the foremost, non-profit, independent expert in diamond research, education and grading.

We typically do not like to go below SI2 or I color diamonds and we like to avoid florescence.
