Hi everyone.
I make jewelry more as a hobby and by commission and I have someone who wants me to recreate an old ring that has square shaped stones but they are very simple like a square pyramid with the top cut off. (not a square princess or square step stone, too many facets). I create my jewelry models and even the gem stones that will fit on the computer. Is there a gem cutting or gem sourcing company that likes to see the exact shape and dimensions by opening up 3d models? Since I’m not a jeweler by trade, I don’t even know the gem shape names enough to communicate well so if there are gem cutters that like opening up models and going by exact dimensions and shapes that way, it would help me get the project done. I was thinking of trying Lambert in Thailand but not sure if they like 3d models? Thanks!
I assume that for normal jewelry construction, you get the gems cut first because they want to cut the gem at the best optimum tolerances. But I’m recreating and designed the ring first and now have specific dimensions for the stones. But by luck, the original stones had a lot of inclusions and is a 400 year old ring so the stones look beat up. So rough cutting any gems should work. I just don’t know where to seek them.
Hello Rick,
There is allot going on - or not - in your two posts. But perhaps one start’s with a guess based on your description. The shape and cut is what is could be a “portrait cut”. The expert cutters will perhaps clarify, where / if I am off; conceptually shape is independent of cut style. But a quick search and by luck I landed:
A good guess ? or not? and the contradiction with the forgoing statement in some of the examples at the above page.
Thank you,
Andy
p.s. I do not agree with all of the text on the page of the link above, but the idea of a portrait orientation as with use of paper for a printer - a shape defined by the origin and up axis [ Y up / vertical / long / X wide / horizontal is there.- one can then rotate the defined shape.
Hi Andrew. Here’s the cut I’m talking about. Super simple but this is how the original ring from the 1700’s is. Perhaps called a coffin cut now? Very easy to cut but the issue is if it’s only 8mm by 8mm by 2mm high, can a typical lapidary person do that or those people only cut larger stones? The other issue is that the original ring had heavy inclusions in the emerald so I can’t use lab created ones I suppose.
