4.20 Ct. Boulder Opal from Australia

I am pleased to present a striking natural Boulder Opal from Australia, available through The Natural Gemstone Company, this specimen weighs 4.20 carat and is fashioned into an elegant oval shape, with precise dimensions of 15.94 x 7.14 x 4.67 mm, the gem displays an attractive tablet cut that emphasizes the broad play of color across its surface, the opal is opaque, with an intense color intensity that jumps between rich blues and vivid greens, and the surface finish shows an excellent polish that maximizes brilliance and depth, importantly this stone has received no enhancement, it is entirely natural and untreated, and it embodies the rugged beauty and durability that make Boulder Opals desirable for both collectors and designers.

Visually this multi color opal offers a lively mosaic of color, the tablet cut allows large patches of color to be seen without the distraction of facets, so you experience expansive flashes of electric blue and neon green that shift and blend as the stone moves, the darker ironstone backing typical of Boulder Opal provides a dramatic contrast which enhances the perceived saturation of the colors, the oval outline is slim and elongated which makes it particularly attractive for bespoke pendants and inlaid designs, because the stone is opaque the color appears more concentrated and the patterns are stable under different lighting conditions, the play of color is uniform and intense across the tablet surface, with scattered darker matrix inclusions adding character and a sense of provenance from Australian opal fields.

From a practical and design perspective this Boulder Opal is exceptionally versatile, the 4.20 carat weight and the tablet oval shape work beautifully for a center stone in a pendant, or as a horizontally set gem in a ring for a modern, low profile look, the modest depth of 4.67 mm makes it suitable for cabochon style bezels and secure settings that protect the stone while allowing the color to breathe, designers often pair Boulder Opal with warm metals to amplify the green tones or with platinum and white gold to emphasize the blue, because the stone is natural and untreated it is prized by connoisseurs who value authenticity, at The Natural Gemstone Company we take pride in sourcing opals with strong natural color and solid structural integrity, this particular piece combines striking visual impact with practical durability, which is a rare and desirable combination.

For care and ownership guidance treat this Boulder Opal as a cherished natural gem, avoid sudden temperature shocks and prolonged exposure to chemicals, clean gently with a soft damp cloth and mild soap if needed, avoid ultrasonic cleaners and steam cleaning because these methods can stress the material, when setting a tablet style Boulder Opal consider protective metalwork such as a bezel or a low profile halo that shields the edges without obscuring the color, if you would like a custom mounting our team at The Natural Gemstone Company can advise on design options and suitable settings to highlight the stone, we can provide additional photos and measurements on request, this opal is an excellent choice for someone seeking an authentic Australian Boulder Opal with intense color, excellent polish, and no enhancement, please contact us to discuss availability, pricing, and shipping options, we look forward to helping you make this exceptional gem part of your collection.
