3.61 Ct. Boulder Opal from Australia

As a Boulder Opal specialist at The Natural Gemstone Company, I present a rare and striking option for collectors and designers who compare quality carefully. This piece is a translucent, multi color opal weighing 3.61 carats, cut into an elegant oval tablet with dimensions of 13.37 x 9.53 x 3.89 millimeters. The tablet cut preserves a broad, flat play of color, making the intense green and blue flashes read strongly across the surface, while subtle secondary hues add depth. Compared with common white or crystal opals, this Boulder Opal retains a natural ironstone backing that enhances durability and provides a distinctive earthy contrast to the vivid color. Clarity is graded slightly included, evaluated at eye level, which is typical for natural boulder material and does not detract from the gem when set, in fact it can add character that fully polished, heavily treated stones lack. This opal has no enhancement, is of Australian origin, and shows an excellent polish that maximizes light return and color saturation, outperforming many assembled or doublet opals that rely on backing and adhesives.

When placed against other market options, this Boulder Opal offers superior value for those seeking authenticity and longevity. Many sellers offer treated opals or composite stones that mimic play of color but fall short in natural variation and structural integrity. This piece requires no treatment, maintaining natural optical properties and long term stability, making it a better investment and a more honest choice for bespoke jewelry. Its oval tablet shape is ideal for bezel settings and modern rings, where the natural ironstone rim can be showcased as a design element, setting it apart from faceted or fully cabochon stones that prioritize symmetry over character. At The Natural Gemstone Company we select stones for their real world beauty and wearability, and this opal exemplifies that approach, offering intense color, natural origin, and straightforward care requirements. If you value authentic Australian boulder material with vivid play of color, excellent polish, and a usable tablet profile, this 3.61 carat oval is a standout choice that balances rarity, durability, and visual impact.
