Gave my wife her push present a few weeks ago. It is a custom 5.5ct with all ovals. I selected every stone myself oval are very hard to match.... it took me 5 months to find 17 matching stones. They range from SI-1to Internally Flawless and from E to G in color. All are GIA with no Florescence. The very hardest part of matching ovals is I wanted a 1.45 ratio and dimensions within .02mm or each other. My jeweler drew the ring in CAD, 3D Printed the ring in wax then cast the ring in white gold. Here are photos from the process.
