NovRock Stone Co., Ltd
Rock Stone Co., Ltd. can be tied with reasonable confidence to Phnom Penh and Imperial Crown Condominium, but its standalone corporate history is only lightly disclosed in public. Cambodia's Ministry of Commerce trademark gazette lists ROCK STONE CO., LTD. at No. 41, Street 322, Boeung Keng Kang 1, and records the Imperial One mark in class 37 in 2021. Earlier industry coverage described Imperial Crown as a development by Taiwan-based Rock Stone International, while current property platforms use the RockStone Group name. The project trail is therefore visible, but the relationship between these names and the legal entity appearing in a specific transaction should be documented rather than assumed.

Overview
Rock Stone Co., Ltd. can be tied with reasonable confidence to Phnom Penh and Imperial Crown Condominium, but its standalone corporate history is only lightly disclosed in public. Cambodia's Ministry of Commerce trademark gazette lists ROCK STONE CO., LTD. at No. 41, Street 322, Boeung Keng Kang 1, and records the Imperial One mark in class 37 in 2021. Earlier industry coverage described Imperial Crown as a development by Taiwan-based Rock Stone International, while current property platforms use the RockStone Group name. The project trail is therefore visible, but the relationship between these names and the legal entity appearing in a specific transaction should be documented rather than assumed.
Track record
One substantial residential development is clearly traceable to the Rock Stone name in Cambodia: Imperial Crown Condominium in central Phnom Penh. Construction & Property Magazine covered the project launch in 2017, and a 2019 Cambodian academic project list associates Imperial Crown Condominium directly with ROCK STONE Co., Ltd. Current property platforms treat the building as completed, although their completion dates conflict: FazWaz states November 2018, while RUMAVI gives Q4 2021. The existence of a finished building is therefore easier to substantiate than a single agreed construction timeline.
Segments and prices
Imperial Crown was marketed as an upper-end BKK1 condominium with an emphasis on elaborate interiors and premium finishes. Public project data are not fully consistent: Realestate.com.kh described a 161-unit scheme, whereas RUMAVI currently shows 408 units and a headline asking range of US$135,000 to US$450,000, while individual unit examples on the same page start lower. For a completed building, a buyer is better served by valuing the specific unit against its size, floor, condition, title status and current resale comparables rather than relying on a single developer-wide price band.
Geography
Rock Stone's verified Cambodian footprint is concentrated in Phnom Penh. Imperial Crown is on Street 360 in Boeung Keng Kang 1, while the Ministry of Commerce gazette places ROCK STONE CO., LTD. at nearby Street 322 in the same district. The sources reviewed did not provide comparably strong evidence of another completed Cambodian development by this legal entity outside Phnom Penh.
Reliability and public record
A useful positive is that ROCK STONE CO., LTD. appears in an official Cambodian record and Imperial Crown can be followed through publications spanning several years; current sources also present the building as completed. Corporate transparency is nevertheless limited. The reviewed public material did not provide current audited financial statements, a complete ownership structure or a primary document conclusively explaining the relationship among Rock Stone Co., Ltd., Rock Stone International, RockStone Group and Beijing Urban Construction. Sources also conflict on unit count and completion date. Buyers can therefore inspect and verify a finished asset directly, but should not transfer the reputation of related names to the legal seller without documentary support.
What to verify
For Imperial Crown today, the central due-diligence issue is not future construction delivery but title to the specific completed unit. Match the seller to the unit ownership certificate, confirm that the building is legally registered under the co-owned-building regime and verify that the unit can be transferred to the buyer. For a foreign purchaser, confirm that the unit is above the ground floor and remains within the permitted foreign-ownership allocation at the time of transfer; Cambodian official investment guidance describes a cap of up to 70% of private residential units in such buildings. Any Rock Stone Co., Ltd. or other entity appearing in the SPA or payment chain should have its role documented, and the buyer should also check management-fee arrears, building rules, common-area condition and any encumbrance on the unit. Because public sources disagree on project scale and completion timing, old marketing data should not be treated as transaction evidence.

renderRender: FazWaz project-profile materialsFrequently asked questions
Is Rock Stone Co., Ltd. genuinely connected to Imperial Crown Condominium?
The connection is supported by several sources, although the company naming is inconsistent. A 2019 project list directly pairs Imperial Crown Condominium with ROCK STONE Co., Ltd.; Construction & Property Magazine referred to Rock Stone International as the developer; and a later Ministry of Commerce gazette records ROCK STONE CO., LTD. in BKK1 together with an Imperial One trademark registration. A transaction should still be based on the exact legal entity shown in the contract and title documents.
Is Imperial Crown already completed?
Yes. Current property platforms present Imperial Crown as a completed building, although they disagree on the exact completion year. FazWaz gives 2018 and RUMAVI gives 2021. For a completed-unit purchase, the physical condition, unit handover record and ability to register the ownership transfer matter more than choosing one portal date over another.
Can a foreigner own an Imperial Crown unit in their own name?
Cambodian law allows qualifying foreigners to own private units in registered co-owned buildings, but not on the ground or underground floors, and a building-level foreign ownership limit also applies. Eligibility should therefore be confirmed for the chosen unit and the available quota at the time of transfer rather than inferred from the project's marketing.
