Love your videos as I find them very interesting and informative 😎👍 As a side note, you mention the girdle when polishing to use less than 90 degrees, but the insert text says “>90” which is actually larger than 90. It should be “

hmm...OK. So I think of a box....the side of the box is a 90 degree angle, that is where the girdle is normally faceted. The bottom (and top) of the box is 180 degrees and that is where the table is cut (for the top). So if you have a lot of material at 90 degrees (because you have only cut the pavilion at this point) you want to trim back a lot of that excess rough from the girdle to the table as it will get cut off when you cut the crown (upper half)...so you want to cut a little over 90 degrees to get this material out of the way and leave just a small amount (less than 1 mm) for the girdle...which will end up being something like .2 to .5 mm (depending on your preference). So in the prepolish you can cut back at greater than 90 degrees and get all that excess out of the way (that cuts from the bottom of the stone toward the pavilion) and then polish the now small girdle at 90 degrees...or you could polish at slightly more than 90 degrees in which case this goes from the pavilion toward the crown side. So...it's confusing but..greater than 90 degrees...watch your facet and walk it toward the pavilion and leave about 1mm to polish your girdle, or less than 90 degrees and walk it just to about 1mm and cut the rest off when you work the crown. I know it's confusing, but if you cut slowly you can see how your cutting is moving toward the pavilion or away from the pavilion...the goal is just to have to polish a small amount (less than 1mm) at this point in your cutting. Hope this helps.

Still waiting for the machine to arrive so haven't even cut one yet, but can't imagine ever not wanting to polish the girdle - it just seems like it would be unfinished otherwise.

I enjoy watching your videos. Cutting gems is something that I want to get into. Maybe I have not seen it, but do you have a video from start to finish? How to clean a rough gem (dug up) to finish. Do you have any recommendations for a machine that is not in the 1k price range?

Thanks! I think you would enjoy gem cutting! No, I don't have any videos on cleaning a dug up gem from the ground, but I do have videos on preforming rough gems. As far as recommendations on gem cutting machines, I have only used an Ultra Tec, now a V5. I don't know of any great machines in the $1K range. A good new machine, with all the accessories, is closer to the $5K range.

I am still very new to faceting and I may have missed it somewhere along the way of both tutorial videos but i am curious if there is anything in the diagrams stating how high to have your protractor on the vertical (Y axis) to do each angle properly?
@mikesackos2208
10 ай бұрын
That is one part of Gem Cutting which you have to learn by experience. After setting the correct angle and the correct index tooth, both of which come from the instructions, you lower the stone onto the lap until it touches the lap...how much depends on experience. The more you lower the stone onto the lap, the more material you will remove.

Thanks for the info. Question....... how do determine the order of cuts start to finish. Yoiu talked about going in a repIring a stone previously cut, but how do you determine what ° you need to do the repairs ?
@mikesackos2208
2 жыл бұрын
For repairs, your best bet is experience. If you have cut a number of say oval gems, and you are repairing an oval gem, you can pretty much figure out which facets need some work. You can 'line up' a facet by using a block of metal (precision cut) on top of your flattest lap, and adjust the quil of your machine, increasing or decreasing the degrees and letting the stone free wheel left or right...when the facet is flat on your metal block, you have it set up to cut that facet...make sense?

Thanks. I try to give both sides to the argument regarding polishing or not polishing the girdle. Regarding the R.I., I normally load the diagram into Gem Cut Studio software and check the performance with the R.I. of the stone I want to cut, then I see if I can make any minor adjustments to the design to improve performance.

hi Boppies.. I have question , if L/W ratio of rough is good enough to cut so then H/W ratio matter to cut that gem or not.... i mean if H/W ration is not good enough to cut the gem but L/W Ratio is good enough of rough to cut the stone .. can we able to cut that stone according to gem diagram??
@BOPIESDiamondsFineJewelry
3 жыл бұрын
Depending on the type of design, if you get the L/W ratio wrong, it will cause problems with your facets. Especially for an oval or marquise. The H/W ratio helps you make sure you have enough rough to cut the final 1/2 of the stone, normally the crown.

The design tells you the C/W or P/W (crown to width or height; pavilion to width or depth)...to adjust, I use Gem Cut Studio...or look for a different design.
