Hey! Time for a recut. Natural Tanzanian spinel, very dark iron-bearing spinel. Went from 6.66 carats to...well...I wrote it down and have no idea where I put the paper, and have already sent out the stone. Oops? Forgot what the measurements were as well. I'll find it somewhere, eventually. But still! Got >70% yield, and there's a dramatic improvement in color in the hand.

Still dark though. Gaaaaahhhh.

Also Jeff I really need to attend your photography lecture in Tucson :)

No detail is too small. Think about it.
Leave no stone uncut.

It's still really dark though. It has the typical iron absorption darkness, but the purple flash really improved post recut. Very minimal loss of face up size.

A larger blue-green Sapphire we found in Sri Lanka. Started out as a 6.70ct cushion.
Image
Finished out at 6.19ct. Most of the work was on the pavilion, where we started with 4 tiers. There are still 4 tiers, though set up much lower, with fewer degrees between them. And, as expected, came out a little darker in color and tone.

I wanted to give zircon a try, but some cut stones are cheaper than the actual rough. Especially if you consider the yield (a cut stone is a very good preform) and the clarity (you can check a cut stone more easily than a piece of rock with an irregular/frosted surface).
So, I hunted for the blue zircon nobody wants: disproportioned, chipped, etc. But clean, with a good color and enough depth to recut it easily.

Now that stone sparkles like crazy. It looks like a blue diamond. A bit fuzzier, tho. ;)

This was fun. 42.85ct Nigerian Tourmaline rough with all kinds of little problems.

Turned into 14.05ct, 14.15mm round, that I cut in a new design of Tom's. It's supposed to be in a Canadian magazine this summer, but you never know until it's actually published.

Cheers,

Lisa


Wow! Just Wow!

The talent we have on this platform is extraordinary. I'm sitting on the couch with my mouth hanging open.

How much did you loose during the re-cutting?

I lose relatively a lot: I got a ~55% recovery, because I treated the starting stone as a preform and I wanted to use optimal angles. Still, much better recovery than the average piece of rough. :)

I think you need to consider two separate factors in evaluating your final result:
1) has re-cutting increased the market value of the gemstone?
2) how much personal satisfaction does the final result give you?

The answer to the first question is purely a commercial calculation, but the second is subjective.
