14.53 Ct. Boulder Opal from Australia

At The Natural Gemstone Company I am pleased to present a single exceptional Boulder Opal that combines the rare beauty of Australian opal with the natural stability of ironstone backing. This specimen weighs 14.53 carats and is cut into an elegant freeform shape that follows the stone s natural outline, offering a uniquely organic silhouette. The gem measures 26.60 x 14.70 x 5.10 mm, and it displays translucent body tone that allows internal play of light to shine through, creating a lively and captivating presence. The clarity is graded as very slightly included when examined at eye level, which means the inclusions are minimal and do not distract from the gem s visual impact. The color intensity is vivid, and the polish is excellent, enabling bright flashes and a smooth touch. There has been no enhancement applied to this opal, so you are viewing an entirely natural, untreated stone, sourced from Australia, which remains the most reputable origin for high quality Boulder Opal.

Visually this stone presents a spectacular interplay of color that is characteristic of premium Boulder Opal, with sweeping areas of electric blue and vivid green, layered with softer aqua and teal tones that shift with every movement. The multi color display is broad and even, creating painterly patterns across the surface that can read as both bold and subtle depending on angle and light. Because this is a Boulder Opal the lower edge retains the natural ironstone matrix, which provides a warm, earthy contrast to the cool, luminous colors on the face. That ironstone rim not only adds to the gem s natural charm but also enhances durability and makes this opal especially suitable for jewelry that benefits from a secure backing. The freeform shape emphasizes the stone s individuality, allowing a designer to highlight the best color plane and to create a one of a kind piece that will not be replicated.

From a design perspective this 14.53 carat Boulder Opal is wonderfully versatile, and it invites creative interpretations while remaining practical for daily wear when set thoughtfully. The length and gentle curve of the freeform profile make it ideal as a center for a pendant that will showcase the shifting color field, and the thin profile of 5.10 mm allows the stone to sit comfortably close to the neckline. For rings a bezel setting is highly recommended to protect the edges and to secure the thin polished surface, and the ironstone backing provides a solid base for prong or hybrid settings that combine strength with aesthetic balance. Skilled setters can accentuate the vivid blues and greens with metal choices such as warm yellow gold to create contrast, or cool white gold or platinum to emphasize the opal s cooler tones. Because this opal is translucent and carries vivid internal play, careful orientation and lighting will bring out the most dynamic color flashes, so custom jewelers often take the time to position the stone to maximize its visual effect.

Caring for a Boulder Opal is straightforward when you understand its nature, and I am happy to share practical guidance as part of our service at The Natural Gemstone Company. Boulder Opal benefits from the stability of its ironstone backing, but it remains important to avoid extreme heat and sudden temperature changes, and to keep the gem away from harsh chemicals and cleaning agents. Gentle cleaning with a soft cloth and mild soapy water is recommended, and professional steam cleaning and ultrasonic methods should be avoided to protect the opal s structure and surface polish. If you would like, we can provide additional detailed photographs, high resolution views of the color play, and measurements for your jeweler, and we offer secure packaging and insured shipping to ensure the gem arrives in pristine condition. As a boutique supplier we stand behind the natural beauty and integrity of each item we offer, and we welcome your questions about setting options, custom design collaborations, and appraisal or certification services.
