3.61 Ct. Multi Color Boulder Opal (Ironstone Opal) from Australia

This beautiful opaque 3.61 carat oval multicolor boulder opal offers an immediate presence that outperforms many market alternatives, the gemstone measures 13.37 x 9.53 x 3.89 mm and is cut in a tablet style to present broad, stable flashes of color. As a Boulder Opal Ironstone Opal from Australia, it benefits from a natural ironstone backing that increases durability and stability compared with thin freeform opal pieces, the tablet cut and excellent polish maximize the intense color intensity noted across the surface, the clarity is slightly included when evaluated at eye level which is typical for natural boulder opals and adds to the stone character rather than detracting from its visual appeal. There are no enhancements, making this a genuine natural specimen rather than a composite doublet or triplet, this authenticity gives far greater long term value than assembled or treated opals and also means the play of color is intrinsic to the stone rather than applied or stabilized.

Compared with other gemstones in this size and weight class, the 3.61 carat oval tablet boulder opal is exceptional for its balance of vivid color and rugged support from the ironstone matrix, it is a more practical choice for everyday wearable designs than fragile crystal opal or delicate white opal, the oval tablet shape at 13.37 x 9.53 mm is ideal for classic bezel settings and inlay work, the slightly included clarity is acceptable for this material and often signals natural origin and unique patterning that cannot be replicated by synthetic alternatives. At The Natural Gemstone Company we prioritize ethically sourced Australian material and careful cutting to preserve natural color and stability, this piece is a standout for designers and collectors who value natural character, excellent polish, and uncompromised authenticity.
