EDGE TREATMENTS
Hand Tooled for Old World Charm
Bluestone edge treatments create distinctive finishing touches for any project, including pool and spa coping, steps, hearths, and pier or wall caps. Our team fabricates each edge with precision, ensuring a clean, high‑quality result every time.
In addition to the standard flamed edge, we also offer a wide range of hand‑crafted edge styles for our thermal treads and coping. These options give you even more flexibility when designing your outdoor space.

Lastly, we do not provide edge treatments on natural cleft stone; we offer these services only on thermal material.
Flamed Edge
The flamed edge serves as our standard edge treatment, and it delivers a clean, natural appearance. To create this finish, we cut the edge at a 90‑degree angle from the face of the stone and then torch it, which enhances the natural texture and avoids the saw marks or imperfections that a sawn edge can reveal. In addition, the flamed edge provides the same matching finish as the top surface of our treads, ensuring a consistent look across your project. Finally, many customers also refer to flamed edges as “thermal” edges, since both terms describe the same process.
Rocked Edge
The rocked edge creates a bold, rustic detail by chiseling both the top and bottom of the dressed edges by hand. As a result, the stone gains a more pronounced, natural character that stands out beautifully in traditional or historic designs. In addition, this centuries‑old technique delivers an authentic hand‑cut feel wherever that look is desired. Finally, many people also refer to this style as a “rockface” edge.
Full Bullnose
Our full bullnose edge treatment offers an excellent option for anyone looking for a smooth, rounded‑over edge. To achieve this finish, we first round the top and bottom of the stone and then apply a thermal treatment, which enhances both texture and durability. In addition, this edge style is commonly used on spa and pool coping, since it creates a more refined and formal appearance
3/4″ Radius Round-Over
Unlike a full bullnose, the 3/4″ radius detail rounds over only the top portion of the edge, creating a softer, more comfortable profile for any project. As a result, this treatment works especially well for pool and spa coping, benches, and countertops, since it eliminates the sharp or pointed edges that can feel uncomfortable when sitting or leaning. In addition, we offer several radius variations—such as 1/4″, 3/8″, and 1/2″—so you can choose the exact level of rounding that best fits your project’s requirements
DuPont Edge
The DuPont edge is essentially a ¾” radius round-over depressed into the stone. Unlike other edge treatments, after the DuPont edge is fabricated, it is left with a diamond rubbed finish and not re-flamed. It is used for more formal applications or in combination with other edge treatments.
Cove DuPont Edge
The Cove DuPont is an elegant edge detail and is the most ornate treatment we offer. This edge gives a sophisticated look to any project. Quite popular for hearths, mantels, pier caps, etc., the Cove DuPont edge has a series of interesting impressions in the edge profile producing a look of timeless elegance.
