14.39 Ct. Boulder Opal from Australia

Thank you for considering this exceptional Australian Boulder Opal from The Natural Gemstone Company, a rare and visually captivating gem that stands out for its size and vivid play of color. This stone weighs 14.39 carats, and is cut into a freeform shape, with measurements of 18.10 x 17.30 x 5.10 mm. The cut is not applicable in the traditional sense, as the freeform design follows the natural contours of the rough to maximize the display of color and character. The body of the opal is translucent, allowing light to pass through and enhance the internal display of color. The clarity grade is very slightly included, evaluated at eye level, which means that minor natural features are present but do not detract from the overall beauty or brilliance. The color intensity is intense, and the polish is excellent, giving the gem a smooth, reflective surface that shows off its multi color fire to full advantage. There has been no enhancement applied to this stone, which preserves its natural integrity and value, and its origin is Australia, a source renowned for producing some of the world’s finest opals.

As a Boulder Opal, this gem displays a delightful interplay of reds, greens, blues, and flashes of yellow and orange that shift in appearance as the viewing angle changes. The patterning is lively and broad, with areas of saturated red and orange that contrast beautifully with cooler greens and blues, creating a three dimensional effect that draws the eye. Boulder Opals commonly retain a thin natural backing of ironstone, and this piece benefits from that characteristic, which adds depth and contrast to the lighter translucent layers above. The result is a stone that feels both ethereal and grounded, ideal for a statement piece that needs both presence and subtlety. Given its dimensions and visual impact, this opal would make a stunning centerpiece for a pendant or a custom ring, and it can be set in a bezel, cup, or partial bezel setting to protect the edges while showing off the surface play. For settings, warm metals such as 18 karat yellow gold or rose gold will emphasize the red and orange flash, while white gold or platinum can make the greens and blues appear crisper and more modern. The thickness of 5.10 mm offers a substantial feel, but because Boulder Opals often have delicate surfaces, a protective setting is recommended, especially for rings that may be exposed to daily wear.

When you purchase from The Natural Gemstone Company you receive more than a beautiful stone, you receive the expertise and care of a team that specializes in natural gemstones and personalized guidance for jewelry creation and maintenance. This opal is offered without enhancement, so its colors and translucency are entirely natural, and the excellent polish ensures that the surface is ready for setting. The very slightly included clarity grade serves as a reminder that this is a natural gem with character, not a synthetic or overworked imitation, and such inclusions often add to the uniqueness of the piece rather than detract from it. Caring for opal involves avoiding sudden temperature changes, prolonged exposure to harsh chemicals, and strong knocks or abrasions. Clean gently with a soft cloth and mild soapy water, and avoid ultrasonic cleaners or steam cleaning. If you would like, we can provide additional photographic angles, suggest setting options that protect the stone while showcasing its color, and work with your jeweler or ours to create a custom mount that reflects your personal style.
