Would you recommend shopping for a diamond from Costco? From the reviews, it seems that the appraisal values for these diamonds are often times higher than what the buyers paid for.

In particular, would you recommend buying the following diamond ring?
https://www.costco.ca/three-stone-round ... 58556.html
Hi,

Good question, I personally buy almost every thing that I can at costco as they have amazing prices. With jewelry Im fortunate to know exactly what things cost so the best advice I can give with Costco jewelry is that their lower cost items can some times be
really great value. Ive seen some mens bands and cheaper (sub $1000) ladies rings that are priced at barely over what it would cost me to manufacturer them. This isnt the case with more expensive items, im not sure why, but as the price goes up the value really starts to deteriorate. If I had to guess I would say that Costco cant exercise as much buying power in this space to reduce their pricing like with many other items, and the fact that there are bit carrying costs to stocking inventory make it hard for them to keep competitive.

The ring that you linked to would be decent value compared to a brick and mortar store but easily a few thousand dollars more than I would say would be competitive. Also what I dont like is that Costco switched to IGI graded diamonds which IMO have
less accuracy in grading than GIA, especially in more arbitrary aspects like diamond cut and some times color and clarity.

Hope that is helpful

Hi,

Yes when the diamond crosses the border into Canada you will have to pay sales tax at your provinces rate and this will likely be collected in advance or charged by the shipping company. Provided the piece of jewelry is made in North America or a country with preferential
trade you shouldnt be charged duties.

Thanks
Hi,

The cut on paper seems to be pretty good, crown and pavilion angle work well together.
At VVS2 you have nothing to worry about for clarity it will be eye clean 100%, likely a bit over kill for clarity IMO.
H color is mostly safe, aside from the odd one with a slight brown or grey tinge.

Price wise 18000 isnt to bad for this diamond but depends where your shopping. For brick and mortar it would be a good price.

Your expertise, and willingness to help, is extraordinary, thank you.

When you say expensive, is something like this considered expensive, in your mind?

Hi DiamondShopper,

Is the color degradation noticeable from I -> D?

Is there much difference from a "Very Good" cut to "Ideal" cut?
According to many websites it says that:
Very Good: High quality cut that reflects almost as much light as an ideal cut diamond, yet at a more affordable price.
Ideal: Superior quality cut that produces a striking balance of fire and brilliance. Only 3% of the world’s diamonds are ideal cut.

Just wondering if in your opinion is it worth cutting down the diamond size for a better color or cut? My price range is around 5k.

Hi, Your very welcome glad to be helpful!

Typically for rings with small center stones and many accent diamonds costco seems to be a decent value.
I havent see one of their rings in a long time as we no longer repair jewelry not sold trough us so I cant comment on the quality which is of course a big component.
I suspect that the rings are made over seas with a high focus on being in expensive which in some cases can lead to diamonds falling out, poor cut small diamonds ect.

Overall in comparison to most BandM jewelry stores there is good value. I can really say which I would like as I have no idea what the quality is and accuracy of center stone grading as well
it seems like all are reasonably similar (.7ct center stone and many accent diamonds) with the main difference in the style.

Hi,

I would say you would definitely notice the difference between D-I color especially side by side. There are alot of other factors that go into how the color will appear such as the diamonds shape where some shapes show more color than others.
As well as how well cut the diamond is. A poorly cut F color will likely look like it shows more color than a well cut G color. DEF are very similar in terms of color, I doubt you would seen a tangible difference between them from the top view.
As well I cant often see much of a difference between one color grade in a mounted diamond and I look at diamonds all day. In the HI and lower ranges you start to see more varying color tinges like brown, green and grey which show much more than
a yellow under tone. I attached an image below with diamonds D-I in the face up and side position so you can see the basic difference. There is definitely more of a difference noticeable from the side view.

I wouldnt agree with the statement on VG diamonds at all as the majority are cut deeper, with mismatched crown angles and potentially thicker girdles. This can affect much more than just light coming of the diamond, it can lead to showing more color, looking smaller
for the same carat weight, having things like fisheye effect, the list goes on and on. Some times there are a few VG diamonds that arent bad but for the most part the savings arent enough to compensate for the other trade offs. I would suggest you read the thread summary
as there is some great info on the above two points.

James Allen dosent show the reports for the diamonds so I cant offer too much in terms of advice as Im limited in the info I have. If your considering princess cuts, GIA does not grade fancy shapes for cut so when you read ideal cut there is really no basis for that
as the only lab that grades cut is AGS. The first diamond is graded by IGI and both the color and clarity look to be off a grade or at the best bordering the lower grade. For the GIA diamonds the .7ct has a decent face up size for the weight, the .8ct is a bit on the small side.
It almost has the same proportions as the .7ct. I have seen some great I color princess cuts, if chosen properly (lower depth and gridle, table not to large or small and lower chevrons) so I would say if your looking to maximize size you can find great value in H-I color.
For clarity if your only concerned with what you can see with the naked eye you can go as low as SI2 for an eye clean diamond.

Hi there, looking for an opinion on this lab diamond: I'm told that this will be eye clean with only a transparent feather on the crown. On paper the specs look quite good, but I have no idea what to look for lol so would appreciate any advice as I am being told I cannot get any more pictures or videos.

Hi DiamondShopper,

Thank you for all the advice that you've given and the time you've taken to help everyone.
I think I've gotten to the point where I'm looking at the price range for around 4~6k for a cushion cut diamond.

As you had indicated before, the cut is a huge difference on the shine and the color has a tremendous impact on how it will shimmer as well.

I'm wondering if you have any comments about this diamond: https://www.bluenile.com/ca/build-your- ... LD14033230
BlueNile provides a "similar" diamond, and this one is almost 2,000 dollars more, but the measurement is much smaller. https://www.bluenile.com/ca/build-your- ... lternative

Is there any reason why this would be the case?

Thank you so much!

Right around when Covid started there was an across the board price decrease of 5-7% in the wholesale market. Which is quite a bit.
Many cutters and brokers fought the proposed decrease so it was reversed.
Currently there isnt much in terms of discounts, with diamonds typically you will only find sales and deals in retail environments where the margins are all ready very high. With the cheaper online stores and direct to consumer brokers
there arent really deals as diamonds are some what of a commodity at the wholesale level with stable pricing. IF you are looking to save money your best to avoid brick and mortar as you likely have to pay for their overhead and if you work
with some one knowledgeable they can likely find you deals and value by choosing diamonds that are priced low for the quality.

Good luck

The cut appears to be nice based on the specs on the report.
I would guess that it is eye clean from the images but they are a bit hazy.
With IGI lab grown diamonds are really a mixed bag in terms of grading. Some times the grades hold up to GIA standards and sometimes they are a grade or so off. In this case even if a low SI1 it looks like it is a fair SI1.
My concern would be the color. The videos are a bad indication of color so I would ask if the diamond holds up as a GIA H. I color can be ok too but that is where things start to go wrong and can show alot of color and
sometimes brown tinges. With lab grown diamonds more so than mined you really need to trust the person you are working with to do the due diligence. As there can be alot of things that arent listed on the report that can go wrong.
