Blue zircon is the only colored gem stone that is more brilliant then diamond, due to the double refractive nature of the stone. It has a great blue color. Zircon is a natural gem stone and comes in a verity of different colors. It has the hardness of 7.5.
Here are a few pieces that I have made over the years:
Denice always regretted setting a peridot in her ring when the original trillion blue zircon, got damaged.
I told her, that in the event we could not find a new blue zircon trillion cut stone in budget, we could rework the ring to accommodate a different shape stone.
We found a nice round stone that she was happy with.
I got to work, first, cutting off the old trillion gallery.
It left a huge hole and seat that needed to be filled. I did a controlled melt of white gold to fill the hole. I slowly brought the ring to the melting point and added beads of gold. Then pulled back the flame. I kept adding small beads of white gold until it was filled in. No solder was used.
I grind, sanded and shaped the area smooth.
I lasered on a fabricated “donut” of gold for the new seat/gallery.
I tack lasered on a big prong and then soldered it in place.
I cut a seat and set the stone.
Cleaned up and polished. The ring does not look like it went through a major remodel.
