Magnificent 14.68 Carat Square Cushion-Cut Fall Bicolor Tourmaline: A Treasure for the Discerning Collector or an Exceptional Gift - Merkaba Beverly Hills Offered unmounted for the most discriminating eye, this 14.68 carat Fall Bicolor Tourmaline presents an extraordinary opportunity to own a gemstone of rare beauty and undeniable sophistication. Perfectly suited as a lavish gift for a special lady or gentleman, and equally at home in the collection of a connoisseur, this Tourmaline captures the essence of autumn’s most vivid hues in a single, mesmerizing stone. The gem’s superb pedigree and impeccable quality will surely enchant collectors and 1stDibs luxury shoppers seeking the world’s most exclusive treasures. A Dance of Colors What distinguishes this Tourmaline is its “Fall Bicolor” coloration—shifting seamlessly from one hue to another as light moves across its facets. Reminiscent of the fleeting beauty of fall foliage, the gem displays subtle gradients that may reveal shades of warm gold, amber, olive-green, or even a hint of wine-like crimson, depending on the viewing angle and illumination. This phenomenon of natural color zoning is visually captivating and profoundly rare, making it a prime example of why Tourmalines are revered for their diversity and vibrant range. To own such a Precious gemstone is to possess a miniature masterpiece sculpted by nature. Exceptional Square Cushion-Cut Measuring 14.40 mm x 14.40 mm x 10.70 mm, this Tourmaline has been fashioned into a square cushion-cut—a shape that harmoniously merges the timeless appeal of a classic cushion with the refined symmetry of a square. Each carefully placed facet enhances the gem’s brilliance, creating a kaleidoscope effect of color play and sparkle. Light effortlessly bounces from one facet to another, transforming the stone into a radiant focal point. When incorporated into a piece of Luxury jewelry, the gem’s regal presence will rival that of more traditional favorites like Sapphire rings, Rare diamonds, or Designer ruby jewelry. Uncompromising Quality and Collectibility For those drawn to the world of Fine jewelry and Exotic gemstones, Bicolor Tourmalines hold a special allure. Their formation, influenced by changing trace elements during crystal growth, produces natural color zones that fascinate both seasoned collectors and new enthusiasts. In this 14.68 carat stone, the clarity beautifully showcases its contrasting hues, allowing each color to stand out while seamlessly blending into its neighboring shade. This rare combination of color shift, generous carat weight, and impressive clarity elevates the gem to an investment-worthy level—ideal for those who frequent Luxury jewelry stores Beverly Hills or who seek to make a statement on 1stDibs. A Personalizable Masterpiece While already awe-inspiring in its unmounted form, this stone’s true magic comes alive when given the opportunity to grace a piece of Custom jewelry. Our in-house design team offers supreme custom jewelry work, allowing you to design your dream setting for this one-of-a-kind Tourmaline. Whether it takes center stage in a grand cocktail ring reminiscent of High-end statement jewelry, becomes the focal point of an elegant pendant in Gold jewelry Beverly Hills style, or evolves into a meticulously crafted heirloom bracelet with diamond accents, every detail will be tailored to your vision. From selecting the metal—platinum, white gold, or yellow gold—to choosing complementary side stones (think Rare diamond jewelry Beverly Hills, Designer garnet anniversary necklaces, or Exclusive aquamarine statement jewelry pieces), the possibilities are endless. A Gift of Enduring Significance For gift-givers hoping to impress someone special—be it a birthday celebration, anniversary milestone, or a heartfelt token of admiration—this Fall Bicolor Tourmaline surpasses the ordinary. Its warm, inviting tones resonate with the spirit of transformation and renewal, symbolizing both the splendor and the fleeting beauty of autumn. Presenting a stone of this magnitude not only conveys refined taste but also carries a story of natural wonder, making it a gift to be cherished forever. In a world of Rare ruby jewelry for collectors, Precious alexandrite heirloom necklace designs, and Sapphire engagement rings, this Tourmaline emerges as a unique alternative that stands apart for its nuanced coloration and storied origins. Customer Assurance and World-Class Inventory We stand behind the excellence of this gemstone, offering a 7-day return policy with return shipping covered by us. Such a commitment ensures peace of mind, allowing you to explore the stone’s charm firsthand.
