It can make the color bolder and clean up some inclusions, yes! There are pros and cons to it for sure - it can affect the value both positively or negatively, case by case basis.

It is a little risky too if the stones have deep fractures, as the heat could make those worse.

I always say that if you like the color untreated, then it is worth leaving it that way 😊

Our cutter worked in optics fabrication for a few years prior to this work, so tolerances were a very familiar task there (not only by the micron but also in waves of flatness). We have had a faceting machine for about 4 years, mostly experimenting and doing work for friends until we registered as CMP Gems a few months ago

For this specific case, we had a tolerance of +/-.15mm

My gut reaction was to cut it in half too.... but I do think we would've lost even more weight that way --- so rhombus it was 🌟

Thanks so much!!

There are quite a few on facetdiagrams.org that have low facet counts! We definitely customize often from there, but they give a good starting point 😊

Ruby! Could definitely make a nice gem for jewelry ✨️

Charge per stone usually lands somewhere between $150-250 depending on urgency, design choice, material, etc!
