Ooids are tiny nodules formed from the accumulation of carbonate material around a nucleus. When cemented together and lithified, these ooids can form rock. Oolitic limestone forms in reef or lagoon environments, and is useful in the classroom for lessons on depositional facies, sedimentary rocks, and stratigraphy.While each specimen will vary slightly in shape, size and color, it will measure approximately 1" in length. Specimens are packaged, labeled & barcoded for easy identification and storage.Selected & Processed by a Geologist.Each and every specimen is selected and hand processed by an actual geologist, ensuring that each sample exhibits defining features. Rocks and minerals are sourced from a variety of locations around the world and are processed by hand in Victor, NY.Technical SupportAlways feel free to reach out to our team of scientists and geologists for additional information, or to assist you with any questions regarding our rock and mineral samples. Review: Perfect Addition to My Triops Habitat - I purchased this to enhance my triops' aquarium, and they've been fantastic! The hand-processed quality and unique oolithic texture make them visually appealing and a great addition to the habitat. The rocks are the perfect size for small tanks, and my Triops enjoy exploring them while it also helps maintain the pH of the water. Highly recommended for aquarium enthusiasts and educators! Review: Amazing value, and it gets delivered! - This rocks are pretty decently sized. I actually got 13, so I think that shows you’ll definitely get the 12. The value is there for the price, aquarium limestone was 3x the price at my local fish store. These work in my fish tank at increasing my kH and pH slightly. It helps stabilize the tank water and I’ve noticed it working. ## Features - OOLITIC LIMESTONE | Oolitic limestone is a carbonate rock formed from the cementation of thousands of ooids.

It felt like a lot of money for six little pieces of limestone (to someone who used to live where every streambed was full of limestone pebbles!) -- but each stone can be used more than once, as there's no need to let it sit in the vinegar until it disappears, so there's that. I still want to ask a friend in Indiana to just send me a bag of rocks for the price of postage. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/244510888-eisco-6pk-oolitic-limestone-sedimentary-rock-specimens-approx-1-geologist](https://www.desertcart.hr/products/244510888-eisco-6pk-oolitic-limestone-sedimentary-rock-specimens-approx-1-geologist) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-05*
