3.00 CT Square Princess Diamond Necklace in 18kt White Gold

David Stern Jewelers presents a magnificent 3.00 CT Square Princess Diamond Necklace set in luxurious 18kt white gold, an exceptional piece that showcases one of the most brilliant and contemporary diamond cuts in substantial, impressive proportions. This stunning creation features a commanding 3 carat square princess cut diamond displaying beautiful sparkle and fire, representing one of the most popular modern diamond cuts for those seeking maximum brilliance with a distinctive geometric aesthetic. According to the Gemological Institute of America, diamonds rank 10 on the Mohs hardness scale as the hardest naturally occurring substance, making them perfect for jewelry designed to be worn daily and treasured for a lifetime before being passed down through generations as cherished heirlooms.

The spectacular 3 carat square princess cut diamond represents a substantial investment and impressive centerpiece that commands attention while maintaining elegant proportions. The princess cut, developed in the 1960s and perfected throughout the 1980s, is a square modified brilliant cut featuring intricate faceting that creates exceptional fire and scintillation rivaling the traditional round brilliant. The International Gem Society explains that princess cut diamonds feature 57 or 58 facets arranged in a distinctive chevron or X-pattern visible through the table, creating flashes of colored light that make this cut particularly eye-catching and contemporary. The square shape with pointed corners creates a bold, modern aesthetic that appeals to those seeking an alternative to traditional round diamonds.

Princess cut diamonds offer several distinct advantages that make them particularly desirable for statement jewelry. The square shape provides a larger apparent face-up size compared to round diamonds of equivalent carat weight, creating maximum visual impact. Additionally, the princess cut’s faceting pattern conceals color and clarity characteristics more effectively than step cuts like emerald or asscher, making it an excellent choice for optimizing the appearance of near-colorless diamonds. The geometric precision of the square shape creates a contemporary, architectural quality that works beautifully in modern jewelry designs.

This Necklace has a Total Carat Weight of 3.00 ct tw with I color and SI-1 clarity. The I color grade falls within the “near colorless” range on the GIA diamond color grading scale, offering exceptional value while appearing virtually colorless when set in white gold. GIA grading standards indicate that I color diamonds show only slight traces of color that are difficult for the untrained eye to detect, especially when mounted in jewelry. When set in white gold, these diamonds face up beautifully white, offering the look of higher color grades at a more accessible price point, allowing you to maximize carat weight and overall impact.

The SI-1 clarity grade indicates the diamond has minor inclusions that are difficult to see under 10x magnification and typically invisible to the naked eye. The American Gem Society notes that SI-1 diamonds offer outstanding value for discriminating buyers, as they provide eye-clean appearance while remaining accessible for those seeking substantial carat weight in fine diamond jewelry. This clarity grade represents an ideal balance between beauty and value, allowing you to enjoy a 3 carat diamond’s impressive presence without paying premium prices for microscopic perfection that provides no visible benefit.

This Necklace has a gold weight of approximately 7.8 grams, with the diamond setting crafted in premium 18kt white gold while the chain is constructed in 14kt white gold. According to the World Gold Council, 18kt gold contains 75% pure gold, offering substantially higher precious metal content than 14kt gold. The choice of 18kt white gold for the setting ensures maximum durability and security for the valuable 3 carat diamond, as the higher gold content creates a denser, more wear-resistant metal that will protect your investment for decades. The 14kt white gold chain provides an excellent balance of durability and value for the necklace portion.

Both metals are rhodium-plated to achieve their brilliant white finish, creating a seamless, contemporary aesthetic that allows the diamond to command full attention. White gold is the perfect choice for diamond jewelry, as the cool white metal tone creates a neutral backdrop that maximizes the diamond’s brilliance without any color interference. The substantial 7.8 gram gold weight indicates quality construction with properly sized prongs and settings designed to securely hold a 3 carat diamond for generations of wear.

This Necklace comes with a 16 inch chain with a lobster claw clasp in 14kt white gold, a classic and flattering length that positions the substantial princess cut diamond pendant at the collarbone for maximum visibility and dramatic impact. The 16-inch length is particularly well-suited for showcasing a 3 carat diamond, as it ensures the pendant remains the focal point while working beautifully with everything from elegant evening attire to sophisticated professional wear. The secure lobster claw clasp ensures safe wear while maintaining the refined aesthetic that defines fine jewelry design.

What distinguishes this diamond necklace is the substantial 3 carat size combined with the contemporary appeal of the princess cut and the premium quality of 18kt white gold construction. A 3 carat diamond represents a significant milestone in fine jewelry, offering commanding presence that announces success and refined taste. According to international diamond market data, 3 carat diamonds represent less than 1% of all diamonds mined globally, making them genuinely rare and increasingly valuable as investment pieces. The combination of substantial size with the modern princess cut creates a piece that is both classic and contemporary, timeless yet distinctly current.

The GIA Graduate Gemologist credential represents the jewelry industry’s most respected gemological qualification, ensuring you receive authoritative expertise and complete transparency regarding this valuable acquisition.
