Semi Mount to fit Pear Cut - Please Help

[chrono]

I got the pics to magnify. Yay! The sapphire does indeed have a medium sized window due to it's shallowness. While total depth percentage doesn't always tell the full picture, this sapphire is considered shallow. Coloured stones need to be 65% to 75%. Any lower and you'll get windowing. Any deeper and you'll get extinction and pay for weight you cannot see. Worse yet, this window, while narrow, goes from one end of the sapphire to the other end, along the longest width. You CAN see it in the hand shots. It is a bit of a challenge for those with untrained eyes because the stone looks all fuzzy (cannot make out a single facet other than the table or a crown facet or two). As for the inclusion, ask the vendor if the inclusion breaks the surface of the stone. Overall though, I would pass on this sapphire unless you are able to lower the pricing or absolutely have to have it.

I do like that type of window (cut) so I isn't that type of "compact". Yes, I can see that it looks fuzzy at the hand shot but the other pictures look really clear so I dont know. AGL has certified the color to be of very good quality, so that is the main reason I am interested in this one especially, it looks very vivid in the photos. I will ask them regarding if the inclusions breaks the surface. I might also find another sapphire. I know that AGL reports do cost above $400. so I dont know if it is possible to lower their price. including free shipping they only charge $1600. for the gemstone itself.

I'm sorry but I don't understand your explanation. What do you mean by "compact"? Windows are not a good thing so as long as you know that, that's fine. I didn't mean that the stone is fuzzy but that the photography isn't good. In both pictures, I cannot make out the facet pattern except for one or two.

I really don't think it's such a great sapphirre and if you know how to read the AGL report, it says the same thing. It is not a vivid stone at all. If you look at the last sapphire on the link below (far right at the very bottom), that is a vivid pink 2.2 ct round.

Colour rating 4.5 (good to very good) means that it is of average to good saturation.
Clarity rating MI2 to H1is moderately to heavily included
Cut grading 5 (good) means it is of average cut

This is a very average stone.

With "compact" I mean like a small window, almost like a Old European Cut. I personally dislike that type of cut.

Maybe I am misunderstanding the report then because it is stated. color grade: 4.5 / 70 = very good and medium dark and brilliancy 50 percent. I personally think it is very hard to find a gemstone with AGL certified very good color but it might depend on the source, I dont know.

Maybe I will purchase it so I can take a look on it in real and just return it if I dont like it. When I am searching ebay at least I can not find anyone with matching color or even with AGL report. I have to think about this I suppose

I'm afraid this window is NOT compact. With an OEC, it's not a window but a large culet which is round, symmetrical and adds to the look. This window is wide as in <------> across the stone so you can see your skin through the stone. If you decide that even though I've explained it that you really like it, I will put this topic to rest.

4.5 is good to very good, not squarely in the very good range. The overall rating of the stone is only good. A brilliancy of 50% is rather low as well. You don't always need to buy a stone with a report. Find something you like, then have the stone contingent on the AGL $55 fast track brief for untreated status. No need to splurge $450 on a full prestige report unless you are paying a whole lot more. You can see with your own eyes if the colour is good or lacking.

Yes, the listing are ending in 8 days or something so I got many days to think about it. It is so hard to find the "perfect" colored unheated gemstone for the right price.

One last question regarding the mounting piece for the pear sapphire. Quantum cut pears or portuguese cut? I think that portuguese side diamonds will match the cut of the sapphire but I think that quantum cut will make the ring sparkle insanely. I had a quantum cut pear for a long long time ago so I know that they sparkle even more than regular brilliant cut. (stock photos are used) sorry for my poor editing, done in Paint, lol. What is most beautiful?

 

[chrono]

How easily can you get a matched pair of quantum cut diamond pears in the size suitable for your pear?

Not very easily, to get a matching pair of quantum cut pear diamonds I will have to order a pair of 0.50 carats each and get them recut down to 0.35-0.40 carat each.

 

[chrono]

Is your budget sufficient for the loss (cutting fee, plus loss in carat weight of the pears)?
Do you mind if your pear side stones out sparkle the sapphire? It could detract from your center stone.

Yes, I think ym budget will cover it. I will not spend more than a maximum of $4000 for the mounting itself but I think it will cover both the platinum mount, side diamonds and also the recut.

Yeah, that's why I'm asking if I should go for portuguese cut or quantum. I dont know for sure but the pear diamons will be placed a little "behind" the main stone, so it might draw attention to the sapphire as well because of the quantum cut while portuguese cut will just attribute the cut of the main stone? What do you think?

 

[pregcurious]

I would personally do a standard brilliant cut with this sapphire, not even Portuguese. I think Portuguese cuts look better on larger stones. The sapphire should be the main attraction.

To address the window, you may want ask the setter if they can do something with the basket. Has anyone tried modifying the basket to close a window? I have a really hard time with windows, and would rather take an stone that that is slightly deep.

Hmm ... okay ..

What do you mean about modifying the basket to close the window? could you please specify this a little please? The sapphire I bought is almost as wide as it is deep so I bet the depth is somewhere around 95% or something. 9.01 x 6.43 x 6.18 mm.

 

[chrono]

Perhaps she's confusing the pear with the pink sapphire which is windowed? I doubt this pear has a window because it is overly deep.

Yeah, I think that make sense

Finally maked up my mind about the mounting. I found a 3-stone ring in 900PT Platinum (will upgrade to 950PT) with Trapezoid cut side diamonds in size 4 mm (that will fit the size of the sapphire). It do cost only $1200 something I think is very cheap. Dont botter to much about the shape of the head/crown as they will make a new ring that will fit my pear cut (same type of mount design of course).

For the rest of you, I will make a new topic when I have got my sapphire mounted and post pictures. I will add the link to the new topic here.

JeweleryLover - I haven't read all this thread but is the setting you are modifying going to contain a central pear? If so, I'm not sure how it will look with traps for sides. Traps have straight edges and pears are rounded so where they meet there will be gaps/airlines. Can you use photoshop or something like that to put a photo of your pear imposed into the setting?

I have to say that I love a central pear with pear sides. I have a 3 stone diamond ring like that and it gets lots of compliments. I also like the spread across the finger it gives. My vote is for that design (but I'm biased!).

I'm not a setter myself but I think they put maybe 0.02 mm beneath the pear so they are just a little "covered", so the edges wont be able to see.

 

[LD]

To have the sides of the traps covered, the central stone either has to be very high and the setting squished in OR the traps have to be very angled. As Lanbo are making this setting for you, I'm not sure you'll achieve this because unless they have your stone (I wouldn't recommend sending it to them) then it's incredibly difficult to get this exact. The problem is that pears have very different dimensions - you get fat ones, skinny ones, long ones etc. Lanbo will only have a standard pear head that they will use. I'm not sure how much they will customise but it might be worth sending them a photo of your pear with all the dimensions written on it and then telling them you don't want an airline. This is tricky to achieve and I just want you to be aware you're asking them to do a bespoke setting with a cast setting and this can be problematic. The ring in the photo above that looks like it's been taken in a shop looks like it has been made specifically for the stones.

Hope that helps.

I have been thinking about the same thing but the measurements are 9.01 x 6.43 x 6.18 mm (96.1%) stated in the report. So it's very deep. I dont know for 100 percent sure but most of the Chinese jewelry stores make a mold of the gemstone to make a perfect fit (mold after measurements and picture). I know that it is possible to send them the gemstone for mounting but that wont happen. It's not that I dont trust them but I dont trust the shipping agencies in Asia, I just dont.

JL,
The LxHxW doesn't always tell the full picture because the widest part could be closer to the tip or further away from the tip, thereby making it either a skinny pear or a fat pear. So Lanbo knows to take the depth into account? How is your experience with their customization of standard settings

That make some sense, I didn't actually think that way at all. I have never had any problems with any fitting of mountings from Chinese stores at ebay at all. But I have never got a pear mounted so it might be another history. I have only get round, oval, and princes mounted before without any trouble.

 

[chrono]

Yes, it is very easy to get customized settings for rounds and princesses because of their perfect symmetry (equal lengths and widths). It is easy for ovals too because the fattest part is always right down the middle, splitting the stone into 2 identical halves. This is not so for shapes like hearts and pears where the widest part can be closer or further to the tip.

That make sense. So if the head doesn't fit perfectly or there is a problem regarding the pear vs. the trapezoids cuts I will just take it to get fixed by a Local Jeweller, and they might melt and produce a new head for the pear because then I will be able to also deliver them the sapphire for mounting.

 

[LD]

You need to be aware that many local jewellers won't touch cast jewellery settings. They may also have to take the whole ring apart to get the look you want AND it's going to be very difficult to achieve with almost starting again. I don't mean to be full of negativity but unfortunately this is the reality as I learned to my cost!

My concerns are the same as Chrono's. The measurements don't give the full picture. Also I doubt that Lanbo will be taking a cast from your stone (or build a head from your exact measurements) as that's way too expensive for them to do. What they will do is put a standard calibrated pear head onto the setting. This won't take account of depth etc and this is why I'm concerned that your idea of traps may end up not with a look you want. If you look at the head on the ring you've posted, it sits only a tiny bit higher (if not flush) with the traps. That's exactly what will happen when the pear head is put on.

I've had many of my settings customised by Lanbo (I like them very much) but there's a limit to what they produce. In fact, for some settings they can't customise and will tell you so. If you want an exact look and you know that an airline will bother you then you need to think about going the bespoke route (which unfortunately will be more expensive). You could be lucky and they may be able to do what you want - fingers crossed!
