Overview

Set within the gates of Diamond Crest and served by the acclaimed Walnut Valley Unified School District, 1571 Sapphire presents a rare opportunity to own a residence with great feng shui. An example of the excellent feng shui; past owner's child attended an Ivy League university and current owner's son will be attending Stanford. Over $250,000 in upgrades have been invested into the home, including the kitchen, bathrooms, staircase railing, flooring, and custom moldings, adding both quality and refined detail throughout.Built in 1999, the home opens with a grand double-door entry, where soaring ceilings and a statement chandelier create an immediate sense of scale and elegance. Natural light fills the formal living space through tall windows, highlighting the home’s open layout and clean architectural lines. Situated on a 10,000+ sq. ft. lot, the residence offers 4,425 sq. ft. of living space with 5 bedrooms and 5 bathrooms, along with a dedicated office and an expansive, functional backyard designed for everyday living and entertaining. The main level features a private office and a guest en-suite bedroom, ideal for multi generational living or extended stays. At the center of the home, the kitchen and family room connect seamlessly, anchored by a generous island that serves as a natural gathering space. Upstairs, the primary suite offers a quiet retreat with a spacious layout, walk-in closet, and spa-inspired bath. Three additional bedrooms and two bathrooms complete the upper level, providing flexibility for family and guests. Conveniently located near the 57 and 60 freeways, and just minutes from top-rated schools, dining, shopping, and parks, this home combines comfort, scale, and location. Homes of this size, layout, and location rarely come to market—don’t miss the opportunity to make it yours.
