4.93 Ct. Boulder Opal from Australia

I am pleased to present a striking Boulder Opal from The Natural Gemstone Company, a one of a kind, opaque, multi color opal weighing 4.93 carats, cut into a refined oval shape. This gem measures 11.89 x 10.15 x 3.98 mm, and it features a tablet cut that emphasizes broad flashes and a planar surface ideal for showcasing vibrant color play. The color intensity is described as intense, and the stone displays an excellent polish that brings out each spectral hue with clarity and saturation. This opal is natural, without any enhancement, and it originates from Australia, a renowned source for high quality boulder opal specimens. As a salesperson who knows gemstones, I can tell you that the combination of weight, shape, and tablet cut makes this 4.93 carat oval a very wearable size for both statement pieces and more subtle bespoke designs. The Natural Gemstone Company is proud to offer such an authentic Australian boulder opal, and we stand behind its natural origin and unenhanced condition, providing clients with a transparent and wholehearted presentation of the gem.

Visually, this boulder opal presents an evocative dark matrix punctuated by veins and patches of color that range from electric green to fiery red and flashes of deep blue, creating a mosaic like appearance that is dynamic from every angle. The tablet cut flattens the profile slightly, which allows the play of color to read strongly even under diffuse light, and the excellent polish intensifies the sense of depth by allowing light to enter and reflect across the color bearing layers. Boulder opals often include natural ironstone matrix, which contributes a dark background that makes the colors stand out with more contrast, and this specimen benefits from that characteristic, offering dramatic canals and seams of color that appear to float over a rich backdrop. Such patterns are perfect for designers who want a focal point that is equal parts art and gem, and because of the stability provided by the boulder structure, this stone is well suited to practical jewelry such as rings and pendants where durability and daily wear are considerations. If you are considering a custom piece, I can recommend bezel settings that embrace the oval tablet silhouette for protection, or low profile prong settings that emphasize the face up color, depending on whether you prioritize security or maximum visual impact.

From a practical standpoint, this 4.93 carat Boulder Opal is an excellent choice for collectors and jewelry makers who appreciate natural character and uncompromised quality. The dimensions of 11.89 x 10.15 x 3.98 mm offer enough surface area for the color to be appreciated at normal viewing distances, while maintaining proportions that are comfortable for wearable designs. With no enhancements, the gem requires no special disclosure, and its Australian origin places it among the most respected sources for opal with striking color play and natural matrix contrast. Care recommendations include avoiding sudden temperature changes and hard impacts, cleaning with a soft cloth and mild soap if necessary, and ensuring secure settings that protect the edges and face from abrasion. At The Natural Gemstone Company we provide full photographic views and detailed descriptions, and we are happy to assist with custom design suggestions, professional mounting recommendations, and secure shipping options. If you would like additional images, video of the stone under different lighting, or guidance on selecting a complementary metal and setting style, please let me know and I will personally assist you to ensure this beautiful boulder opal becomes a treasured centerpiece in your next creation.
