I design and make jewelry, so I m very familiar with the process. I examined the photos of this pendant before purchasing and could see I would need 3 different sized diamonds. Loaded model into Rhino 7 and voila. There are 112 diamonds in the pendant, and I can't find two the same size, and most of them are not even symmetrically round. I would have to redesign it to repair it. Obvious mistakes here should not be sold in this condition. I will be asking for a refund.
