10.00cts Natural Black Diamond Ring on eBay: Diamond Treatment – Color Enhanced. Is that ok?
Color enhancement is a routine treatment method for black diamonds. So, nothing is wrong with that. Of course, treated diamond (just like any other gemstone) would be cheaper than 100% natural one. Most of the black diamonds are actually color enhanced on the market. So, that's perfectly ok. The proRead more

See lessThe problem with this “diamond” is not that it is color enhanced but that it is not a diamond at all. I mean, it is a fake diamond. Natural black diamonds (enhanced or not) are never this perfect. They do always have some nicks and chips, and the color is never this even and perfect. There is a mixture of black and somewhat grayish areas and even some white dots.
Take a look at the image I have attached here – this is what a real black diamond would normally look like.
The price is another indicator that this is a fake here. $99 would be a reasonable price for a 2.5 to 3-carat loose, color-treated black diamond (if you are buying it at the right place, of course), but definitely not for a 10-carat beauty.
I just wonder how this fraudster has managed to retain a 100% positive feedback…
Ruby necklace on Catawiki: Quality & Price – any issues? Better alternatives?
Dear Emmy, This necklace is not worth EUR 221. This is another example of eBay merchandise ending up on Catawiki's shelves. It is not ruby. In the best-case scenario, this is composite ruby, known also as lead glass filled ruby. In the worst-case scenario, this is dyed beryl. I'm pretty sure this isRead more
Dear Emmy,
This necklace is not worth EUR 221. This is another example of eBay merchandise ending up on Catawiki’s shelves. It is not ruby. In the best-case scenario, this is composite ruby, known also as lead glass filled ruby. In the worst-case scenario, this is dyed beryl. I’m pretty sure this is dyed beryl (just like in the discussion that you refer to). Here is an identical necklace I found on eBay at a fraction of Catawiki’s price – only $19.90. Even with a free shipping 🙂

Natural Top Red Ruby & Fancy Sapphire 728 Cts Necklace on icollector.com auction site. How much should I bid?
FoxyFox, This price estimate, as well as the start price, is the most outrageous nonsense. Indeed, the necklace is very nice. However, it is important to note that these sapphires are diffusion treated and rubies are lead-glass filled. This is a Thai-made piece of jewelry. This is not to say that thRead more
FoxyFox,
This price estimate, as well as the start price, is the most outrageous nonsense. Indeed, the necklace is very nice. However, it is important to note that these sapphires are diffusion treated and rubies are lead-glass filled. This is a Thai-made piece of jewelry. This is not to say that there is something inherently wrong with it; it is just not worth the price. I am 99.9% confident that this necklace comes from eBay seller gemsporium or egemdiamond (actually this is one and the same seller with two accounts).
See lessI’d suggest you check out this seller. There is a pretty good chance that you will find exactly the same necklace at some point. If it is not there at the moment, it might be a good idea to contact the seller and ask him when this necklace will be in stock again.
Normally, the price of such a necklace is around $600 – $700 if you go for “buy it now”. However, if you are lucky, you can win it on an auction at a price even lower than that – $300 – $400. This is what it is actually worth, not $5700. Icollector.com business model is based on unreasonably high price estimates and start prices. In addition, they do not disclose the information on gemstone treatment. Yet another online auction site engaging in dishonest business practices.
SOLITAIRE BLACK DIAMOND STUD EARRINGS on INVALUABLE AUCTION SITE

Dear Ongesa,
No doubt, these are genuine black diamonds. They have all the typical visual characteristics a black diamond would normally have. Thus, no problem with that.
See lessLet me elaborate on this further. The price is unreasonably high for this pair of earrings. This is a rather simple piece of jewelry. Color treated black diamonds are pretty cheap. It seems that the seller hasn’t mentioned anything about treatment in the description, but rest assured that they are color enhanced.
You can get black diamonds like these (or even better) at a price of $60 – $70 per 2.2 to 2.4 carat diamond (on ebay, for example). Mounting settings would cost you another $100 or so + 2 backs at roughly $ 20 per piece (this is what I found in no time; probably you could find an even better deal by investing some time).
So, let’s do the math: (70 x 2) + 100 + 40 + shipping (let’s say another $20) = $300. Mounting is very easy in this case. It should take an experienced jeweler less than 30 minutes. The cost depends on how expensive or inexpensive the jewelers in your hometown are. I’d say it’s maximum extra $50. So, the total cost would be $350.
They sold this pair of earrings for AUD 1200 on invaluable.com which translates into $ 828 + 30% buyers premium = $1076
This is something to consider, don’t you think so? 🙂 $1076 vs $350 😉
12.25 CT GGL CERTIFICATE UNHEATED EMERALD RING 925: eBay
It is very much right what you noted about simulated diamonds. No reasonable person would set a real emerald and simulated diamonds in the same setting. This is definitely not an emerald. That's for sure. It is a bit difficult to tell from the images whether it is a dyed beryl or a dyed quartz. LookRead more
It is very much right what you noted about simulated diamonds. No reasonable person would set a real emerald and simulated diamonds in the same setting. This is definitely not an emerald. That’s for sure. It is a bit difficult to tell from the images whether it is a dyed beryl or a dyed quartz. Looks like beryl to me (quartz is usually lighter in color and the color-concentration zones are more pronounced).
See lessAs far as GGL “certificates” are concerned, if you see a gemstone with a GGL certificate, it is a red flag by itself. Every single “gemstone” I have seen with a GGL certificate so far has been a fake. So, it is no real certificate.
So, I would say that a Thai or Indian-made silver ring with a dyed beryl and simulated diamonds would cost around $15 – $30 on eBay (ok, maybe $40 if it’s supernice).
Emerald necklace – Catawiki auction
Dear Martin, I registered here to answer your question :) Good for you that you didn't bid on this necklace. It is not emerald but dyed beryl. These necklaces are really nothing special, they are made in India, and are very cheap. 150 EUR is way toooo much for it. I hope this helps ;)
