Fantastic gemstones on offer and the auctions are great. Everything I have received has been describer correctly
I give a neutral feedback because the color of stone I received is much lighter than the picture. Then two days later I found the neutral feedback was changed to positive by someone, either the seller or the website. That's a 100% feedback store, and that's the reason why I purchased stone from them. Now I don't know how many feedback was changed by them. Don't trust them!
Comments about the website's reply: They are lying! I have all screenshot in my cellphone to prove it! I didn't give any positive feedback to that seller. I gave a neutral one and surprised to see it was changed to positive by someone else. You can imagine how angry I am when I saw the feedback became 100% positive again. I complained to the website, then 4 hours later the positive one was removed and I can post a new feedback again. I have no objection for the seller refusing to return after 40 days from it's delivered, but I need to say the seller enhanced the color to sell a light-color stone in the feedback.
Again: Don't trust the feedback in their website!

Reply from Gem Rock Auctions
After having bid and "won" 12 different stones,I'm giving this site 2 stars. The only reason for 2 stars instead of 1 star is because 1 seller is a shining example of true honest salesmanship. The site itself is terrible. The administration part. If you leave a negative or neutral review it will be changed to positive. If you don't receive your merchandise, there will be an automatic positive review for that item. And not only do they "automatically" leave positive reviews, they attach YOUR user name to them. I will NEVER use this site again. VERY BAD BUSINESS PRACTICES. If they were in America I would file a complaint with the Better Business Bureau,but since they are headquartered in Australia, I filed a complaint with Ecommerce.
I have purchased quite a few stones from Gem Rock Auctions so far. The pieces are in the low range, less than $500, and I have been very pleased with all the stones I have received. Some of them have been just drop dead gorgeous, beautifully cut, with colors that just pop but all have been exactly as they were represented. My GIA certified jewelry has told me they are genuine, no question.
Delivery has been slow on some of the pieces coming from Asia, but in this time of global disruption because of COVID-19 I am confident that the stones will arrive in time.
I'd say "Happy gem hunting!"
My wife and I are avid collectors. We do buying trips to Bangkok and Chanthaburi every year or so and use gemrockauctions as one of our fillers in-between. Like with most platforms that have a variety of vendors, you will get inconsistencies. Just be smart and remember you're buying gemstones online. Everyone uses different cameras, backgrounds, and light sources.
Our Advice: Read the sellers reviews first, see if there are any complaints that resonate with your concerns. If you want more confidence, buy a couple of cheaper sample pieces form a store that has material you like. Compare them to the videos and pictures, and get a feel for how their setup under or overstates the stones CCC. You can then set your expectations and prices appropriate to each seller. We've even found a couple of sellers that stones are much nicer in person, so (unfortunate to them) people don't bid as high while my wife and I get a great deal.
Also, be patient, wait for the right deal, and make offers. We've had sellers come down to 45% of list price and other that wouldn't budge. We've also watched other stones for months that suddenly come up no reserve; winning them at a fraction of their valuation.
Mostly, know what you're buying. We wont even flirt with buying stones online that we don't have a lot of experience handling.
To close: we've purchased hundreds of stones. One seller misrepresented the color but offered us credit (since it wasn't valuable enough to be worth postage back). Another gave us a full refund on a $600 purchase, no questions ask. Besides those two incidents we've been happy.
I am a New Buyer at Gem Rock Auctions. I have purchase several stones, and every One is Beautiful! I have bought Certified, as well as Non Certifed gems. 4 of the pieces that I was unsure about, after looping them, I brought them to my Jeweler. He asked me where I had purchased them, and when I told him, He almost Fainted. He said the Gems were worth 5-6 times what I paid for them! I will Remain a Very Loyal Customer, & hopefully that won't change.
I am a new user on this site, and my observations so far are:
Seller's with lots of negative feedback are still allowed to sell! Some have MANY comments about FAKE gemstones. This is not at all acceptable. Site rules state three strikes, your out policy,but this appears to be not enforced.
Potential buyers should be aware that the sellers have ratings similar to eBay etc. I recommend that buyers do their own due diligence and research these ratings prior to bidding on anything,as some sellers are very difficult to get answers from after an auction is won. IE: tracking etc.
I'm not confident that the site will assist buyers with obtaining a refund if required.
The " Gemstone Sheriff" appears to me to be seller biased.
The site has no way of attaching photos in messages to sellers,or when opening a Support ticket. This would be a great addition to the site, and the lack of this feature creates a non needed hurdle when trying to resolve any disputes.
As with any online purchases, buyer beware.. what you see isn't always what you get.
Just started on Gem Rock Auctions and am thrilled to have found this option for buying my stones. Easy to use and gives me access to so many.
Would love an option added to the site for combining shipping for multiple purchases from one seller.
I have had good and bad experiences. What i don't understand is vendors with awful reviews get to continue to sell product. There should be someone, somewhere in that places that can control that for customers. After sooo many bad reviews they need to have something in place to let them know you can't keep ripping people off. I personally check everyone of them before purchasing. I had one vendor that i gave 1 good, 1 not so good review (1 good stone and one bad) and he emailed me chewing me out over it then blocked me from buying from him again! Are you kidding me? Had another sell me bad product and once again i was block. I wouldn't purchase again anyway but.... draw your own conclusion. ALWAYS CHECK THE REVIEWS BEFORE PURCHASING!!!
My experience for the most part has been very positive, the items I have received are exquisite and every much as advertised, beautiful. I understand that some of these products come from half a world away, and understandably shipping can be costly. I don't understand why a small item, shipping at 30 days can cost upwards of $30. ThIs completely baffles me and hinders my purchasing quite often. Other than that I must say I am completely satisfied.
An all around great experience with gem rock auctions!! All the sellers I've bought from have been wonderful to work with. Always answer my questions quickly, are helpful and friendly. And also having tools to help you learn about gemology and and so many related topics of interest makes it great for those brand new into collecting clear through to professionals in the field. I have a a whole new world to explore thanks to them.
Fantastic site to purchase gems and jewellery from around the world at some great prices... Bidding for items is a great way to pick up a nice piece for a good price.. I love it and will continue..
The shipping costs for items are expensive, the item may seem cheap to buy however they make their profit by adding expensive shipping cost so to average it out it costs the same not as cheap as the seller pretend to be selling.
Jewelers are honest and conscientious. Many of my purchases are one of a kind. Love this sight!
A novice I love the safeguards built-in, the heads up on total committed by current bids, and the security of knowing the vendors are trusted and if there is doubt - the gemstone sheriff to the rescue!
New to gem rock auctions
Site easy to navigate and follow up excellent.
Made a number of small bids
Waiting for delivery and to see quality
I have been buying from them for 5 years. No major compliants, just minor carelessness which were corrected within the week. Though I have been buying from Chinese stores mainly but I have bought from Aussie owners, Malaysians and Thai stores. They are all okay.
i have NOTHING bad to say about this place. the only opinion i have is that i wish they had an app. i would love that.
