This thread is so helpful! I’m replacing a 7mm x 7.2mm OEC diamond from my engagement ring and putting it back into the cocktail ring it came from. I rarely wear my engagement ring so I am not too bothered by what the moissanite will look like as long as it’s okay. The diamond OEC doesn’t have much sparkle and has some black out spots at certain angles so the fact that the Tianyu gem might just be okay is fine with me. I’m trying to replicate the look of what I have so the OEC makes the most sense.

I do think it all comes down to personal preference. I agree that PSers are Gaga over old cuts! I like them, too, but I think that’s because I prefer subtle bling. I like smaller carat MRB, too!

For sure preferences. Some people like bigger pedals, some like smaller. Some like dazzles and some little settle:D It's all beautiful and fun and my wallet hates me, haha. Can't wait to see what yours look like.

Mmm. I wonder if that's why all the OEC vendors in the the states do OEC videos in the sun, because it can get grey out in the center.

I haven't read all 17 pages but based on my experience I second the comments about middling workmanship and lackluster cut of at least the OEC stones.
I've ordered one thing from Tianyu and it also resulted in overall disappointment. I'm considering placing another order though, because the price was unbeatable for custom. If I do I'll stay simple with a prong-set solitaire. I won't include any challenging features like: milgrain, sharp angles/symmetry, dainty or thin elements, anything that requires a high level of precision and fidelity to design.
That's not Tianyu's fault, and we should all be aware that we're not going to get [popular vendor's] level of craftsmanship at those rock bottom prices.

Price
I was quoted ~$365 for a 14k rose gold size 4 bezel-set ring with a 7.5mm GH OEC moissanite. Shipping via DHL express was another $38 or so. I paid via alibaba's paypal integration.

Communication
A mixed bag. Ella's speed to reply was amazingly quick, and I was communicating via gmail not wechat. However, I also felt rushed to provide approval at each critical step where I asked to pause and confirm details or correct/make changes.
Just one example: I was shown CADs, and being unfamiliar with the custom order process I asked whether the bezel could be made thinner per the inspiration. Ella replied promptly with basically- CADs and the finished ring will look different, but not to worry things will look exactly right once produced. (spoilers: things did not). I should've gone with my gut and pushed further to get what I knew I wanted, lesson learned.

Material Quality
No complaints here. The ring itself is nice and hefty, as I stated was my preference. I couldn't detect any color in the GH moissanite :)

Craftsmanship
I'm just going to do a rundown of the things that I took issue with.
The setting
  • Milgrain is bigger and clumsier than I asked for. It looks fine from the distance most people view another person's ring, but I like to really get up close and examine all the details.
  • Stone started rattling in the bezel the day I received the ring. It's still secure but not tightly secured.
  • There are a few tiny crater-like indentations on the shank that I assume was due to a not highly quality-controlled casting process (air in the metal?)
The stone
  • My biggest gripe is the dead spot in the table facet. Viewed straight-on in LED lighting which is what's in my house and my office, the center seems to suck all the light in and not reflect any of it back. I sent several photos and video clips demonstrating this. Ella insisted that it was not a manufacturing defect and "just the angle". I took this to mean that it's their standard stock OEC cut, so potential buyers beware.
  • The faceting pattern overall didn't wow me either. 7.5mm is big enough to be able to pick out the petals in an OEC and Tianyu's weren't very distinct or crisp. Instead of thinking "ooh, how pretty" (which is what attracted me to OECs in the first place) my reaction was more like, "eh, it's white and sparklyish."
  • The cut is nice and precise! All the meets that I could see on the crown were spot-on. I don't know whether Tianyu is using machines or humans to cut these but they did a great job.

In the end I was offered two options. Ship the ring back and switch the stone out, or a 15% partial refund on the stone itself which would've amounted to ~$17. After sitting on it for a couple of days, I decided to keep the ring and not take either concession. I got desensitized to the dead spot and overall it was a nice enough everyday piece for an unmarried woman in her late 20s. I also didn't want to come off as "nickle and diming" them in case I wanted to do another project in the future.

Hope this helps one of you decide whether or not to engage with Tianyu, and if you do how to navigate the ordering process to arrive at a happy result :D

The clearest, most flattering pic I could take. You can see that the faceting pattern is... indistinct, for lack of a better word.

I had to stop when I saw the price. JUST $365 for the WHOLE ring? Or is the the price just for the setting and you paid a different price for the stone seperately?

I know I try to do milgrain with SG before and it did not turn out great and they ended up redoing the ring for me. Milgrain is tricky for these companies. Don't think they can do the finer precision that we're used to.

Sorry you're not happy with your ring, that sucks. The last picture makes it look really nice though.

I also think they're getting a lot of orders and things are being rushed and getting wrong. Emily quoted me the OEC ring. And then later on, when she asked for more pics she came back and the price majorly jumped. She said she got confused with my pictues the first time around and it's supposed to be more. The invoice I got wasn't right though. The picture of the ring on there wasn't what I wanted, and it said I already put in the deposit, which I didn't. The whole thing was going to cost me $790. I emailed her back making sure she's correct b/c that's the most I'll ever have to pay.

@Lucky_Rabbit for the whole ring, including the stone :)

That's a great price. At least they offer to switch the stone out for you and hopefully could have fix the rattling for you. Though I would be worry about postal to China. I had to sent 2 loose stones back to Tianyu before and it was a nerving process waiting because I heard their postal is pretty corrupt.

Milktoasts, I'm so sorry to hear about your negative experience. My oecs from tianyu look the same - dark in the center and the pattern is also indistinct, as you've said. I think some of us have gotten well cut oecs so maybe it's hit or miss.

Does everyone see a static gray center in natural daylight? Mine always looks pretty white. I only see the gray center if I tip the setting. The stone is 10mm so the petal in the center is very distinct. The ACC moissy’s I have don’t sparkle quite as much in natural daylight for me. It will be interesting to see how the 10 mm H&A compares to my 10 mm OEC because both of them they had to cut for non-stock sizes.

Anyone better at reading CADs have any suggestions on this befor I approve the pics?
Here is the inspiration:

Based off my last experience, I told them no milgrain
and selected a design without any bezels. It looks close to me but I’d love another set of eyes on it before I approve

Wow @anangel this is a pretty and ambitious piece. My only concern would be the view from the side and how the two rings fit together. It may need the gap because of the slope of the main ring. It does look like the Simon G ring though. I have thought that those who like tiny perfect milgrain (like me) could always have it added by a local jeweler later on if they choose. Much easier than trying to fix poorly done milgrain after the fact.

I ordered 4mm OEC studs in platinum and 2mm frenchies in platinum.

My pictures look a bit blurry and I'm so sorry I don't know how to fix that.

The OECs seem dark in the center and not as lively as I think they ought to be. The ring is supposed to be G/H color and compared to my Forever One it's drastic. I don't think this is conveyed in the pics but the frenchies look gray almost like the color of the platinum setting. I'm just not impressed at all. Ugh. The frenchies nor the OECs seem to be crisp either.

I found Moissy gets filthy quickly. Soak them in 140 degree f water with mr clean in it, then rinse. An ultrasonic is better. Do that a few times and see if it changes anything. Use a soft bristle brush also.

It is somewhat ambitious, but based off the feedback here, bezels and milgrain are not their strength, so I made sure to avoid both.
The other option for the ring, would just be straight band. I'm having a hard time judging the height of the band from the pics I have.

I appreciate everyone's honest posts on their OECs they have received. Dark centers are a real problem with poorly cut diamond and moissanite old cuts. I have been hanging onto all my moissanites, even the 3 stone I have for sale on and off again, because of their absolutely gorgeous cuts. No black centers whatsoever. I will probably not order any old cuts from Tianyu because I am so picky. In fact if I tire of settings I will likely reset the stones I have rather than get new ones. They are too precious and I don't want to spend the funds for AVRs right now. I definitely don't need any ACC moissanites since I have a gorgeous ACC diamond already. LOL.

As far as Tianyu's customer service I am completely happy so far. After approving the X ring CAD the other day I was looking at it closer and noticed something that bugged me. I know I am so very picky and hard to please when it comes to jewelry. The Xs were not crossed correctly like the Tiff ring and probably no one would ever notice except me. The ring in the video is incorrect as well. When I emailed Ella she said the ring was already in production and almost done. Ok I understand and it was my fault for not noticing in the first place. This morning she emailed and said they are redoing the CAD and recasting the ring. Yay! It may help them with sales in the long run to have it correct anyway. I am pleased and look forward to getting the ring.

Good idea.

A straight band will have a completely different look and I wouldn't like it myself. I hate a large gap. Others don't mind. I like the top view. Will the side view bother you? If not then the issue is of no consequence. Will the rings be soldered together? This will help keep the look that is intended with the set. Since I would never personally wear any other band with a set like this then I would solder them together but that is up to you and your tastes. I wouldn't have Tianyu solder them though, I would wait until I decided it was needed.

I haven't really seen a halo yet so it will be interesting to see how this comes out. Two things that I wanted to point out but these are personal preferences. I like my rings to have a thickness at 1.8 mm. This seems to be a standard thickness for a sturdy ring but it is all about personal preference. The other thing is the halo airline. It drives me crazy when I can see a gap and I made this mistake on my first halo, which was a round in a cushion halo. I don't like my center stones to lay flush with the halo. I can see the gaps in the corners and they would always fill with dirt. I prefer the halo to almost be tucked under and very tight so you don't see that airline. This is about personal preference but I always like the idea of the setting being built around the stone rather than the other way around. If you have an opinion on this, I would bring it to their attention so there are no assumptions.

.

That was really great customer service that they were willing to recast the ring at that point in production.

Have you ever seen an ACC moissy? I'm curious to how you think it compares to your diamond. I want an AVC so badly but it's hard to justify the cost when I already have an AVC Moissanite. I saw Rhino's videos comparing the two and it appeared to me that diamond was more vivid, had more depth and was crisp.

I haven't seen one in person. I don't know if my ACC being an actual antique from the late 1800's would be a fair comparison to an AVC. Though mine is extremely well cut for being an antique, it is not a precision cut like the new ones. But I love it. I don't wear big stones enough to justify buying another large diamond and am happy with mine. Probably never upgrade either. I can have fun with a few fashion pieces though. My next big diamond purchase will probably be a single cut band from Victor to go with my ACC halo. :love:

@anangel I think the cad looks great! The only thing I see (other than the advice you have already received) is to be specific about the prongs. If you want claw prongs, make sure to ask for them, otherwise they might look 'blobby', for lack of a better term :)

Thanks for all the helpful feedback. I just sent them the notes. I feel bad making so many changes, but I'd feel worse if the ring was finished and didn't turn out well.
I'll post revised CADs when they come. :D

Don't feel bad, that's what CADs are for! They are to make sure you don't end up with a ring you aren't satisfied with. Definitely let us know how it looks after they revise it!

Oh Redwood66, there's something so incredibly romantic about the fact that your diamond is from the 1800s. ❤️

I wonder if anyone has requested the "fat edge" hearts and arrows cut from Tianyu? Just curious, since these look like they have more prominent arrows than their "normal" H&A cut, which it sounds like some of you have found too "splintery".

https://tygems.en.alibaba.com/produ...pm=a2700.icbuShop.prewdfa4cf.1.6e5e49ec4RHWWr
I made an inquiry- I was told all their hearts and arrows rounds should have visible arrows but the difference on this was the fat griddle. I didn’t end up ordering it and got a loose hearts and arrows round. I have to say, the most recent loose stone they sent me had some very nice arrows that were easy to spot even in their gem mailer.

Thanks! That definitely helps, and if I do order a ring or loose stone I'll stick with the normal h&a!

I am not fond of that thick girdle. What is the purpose of it? Sturdiness?


New CAD is here already. I think this looks good? Pic is bigger if you click on it.

Darn near perfection!
I am considering this ring. I can’t wait to see your ring, first!
