Lovely Stones
Great stones, you get 2 huge, 3-4 medium and 4-5 smaller beautiful pieces.
Ava Wein –
Great quality
Good amount of rocks for the price and nice quality, identical to photos. Came nicely packaged and adapted quickly to my tank. Highly recommend for larger tanks (20 gallons and up) due to the large proportions of the rocks and amount of rocks you get ð

Great rocks!
Excellent color, size and shape of stones. A quick rinse is all it takes for immediate use.
Kate –
Excellent
These are beautiful. After reading horror stories about receiving pulverized dirt, small rocks, etc. I was nervous about this – I let these soak overnight and hardly any dust. The two largest rocks are on the bottom, 6 inches and at least 3 inches wide. You can see a couple of others behind the plant where little miss laid her eggs. If you are looking at these you care about your tank, and youâve come to the right site. Thank you for the care in packing! Also, Iâd order these by themselves- Amazon put my other order in the same box, nothing that could be broken but stillâ¦

Quality hardscape
Excellent group of lava stones. Buying something like rocks for hardscape sight-unseen is a gamble to be sure, but I was very pleased with both the selection of stones I received and how quickly I received them.
Amazon Customer –
Maple Leaf Stones
Received the package on time and everything was well packaged and individually wrapped. Seller even includes information on the rocks in the package. Only reason I didnât leave a perfect 5 Iâd one of the larger stones was largely covered in an unattractive mineral (or other stone material?). None of the other stones in the package had this issue.
Mr. Guerilla –
It drives me nuts how much I love these stones!
Color – tanish and mostly the same color.Size – Perfect! Multiple sizes and one or two just rightLooks – Cannot explain the beauty. They shimmer in the light. Almost like theyâre glittery at angles.I was wondering why these rocks were the most expensive compared to the other products they offered. Iâm not regretting my purchase. If you needed any validation, these rocks make me want to steal rocks out of mountainous state parks! lolI have learned thatâs illegal so I wonât but dang it these rocks are worth every penny! Iâm sad to see they have limited stock as itâs not in my budget right now but Iâd love another box for this tank or another smaller one Iâd center these for a single island in a cube tank.Note: when viewing the photos, note there will be a Java fern there later this week.Photo 1 âCrocodile Rockâ/ Video is a 48âL x 12âD tank planted around mountain rocks/ Photo 2 âCaprockâ/ Photo 3 âThe Hamburgerâ/ Photo 4 âGeode-Dude?â

These were actually fantastic. They were far prettier in person with good size variety. It was a total gamble ordering this but if I ever need more I’ll definitely order another box of these.
Themarkman –
Pretty good for a little extra money compared to some others on Amazon. Wish there could have been a bigger piece but thatâs what super glue is for! Febreze bottle for scale.The stone is dense as well and not comprised of small stones held together by clay (like some dragon stone Iâve bought). All in all- solid purchase.
Mark T. –
Pleasantly surprised. Beautiful rocks. I’d say they weigh what feels like more than 17 lbs but I don’t have a scale to weigh. Each rock came wrapped individually in paper.
SFCT –
I really like those stones.I received less (but larger) stones than what I expected from the pictures, however, it’s something the company mentions in their description, so at the end I’m very happy.It’s been a while now and the stones are still there and fit the landscape really well.
