There are luxury homes, and then there is Diamond Bluff Cove. This is a legacy compound, perched above the panoramic waters of Keystone Lake, roughly 20 minutes from Tulsa, and built without a single compromise. Pass through the private gated entry and the scale of this estate reveals itself slowly, the way it should. A modern architectural masterpiece anchors the property, framed by resort-style pool living, phantom shades, and a private pool casita designed for effortless entertaining. Step outside to an outdoor kitchen and sweeping balcony views that make Keystone Lake feel like it belongs to you alone. Beyond the main residence, this compound delivers what almost no other property in Oklahoma can. A barn with stalls and full living quarters for the equestrian at heart. A nearly 3,000 square foot guest home for family, friends, or full-time staff. A large, modern workshop built for serious hobbies and serious toys. And a private drive leading directly to your own beach and boat dock, where the lake becomes an extension of the home itself. Over $3,000,000 has been invested in landscaping alone, transforming the grounds into something closer to a private resort than a residential lot. No expense was spared, and it shows in every detail, from the hardscaping to the horizon. There is also ForeverLawn turf grass surrounding the entire main property. This is the ultimate lake retreat for the outdoor enthusiast and the horse lover alike, a rare offering where privacy, land, water, and design come together at a scale that simply cannot be replicated. Diamond Bluff Cove isn't just a home. It's a compound built for a legacy. See website for additional photos and info. 3 livable dwellings - Main house is 5,712 sqft, 5 Beds & 5.3 Baths.
