1.87 Ct. Cabochon Crystal/Jelly Opal from Australia

One fine example from The Natural Gemstone Company, this specimen is a semi translucent Crystal or Jelly Opal weighing 1.87 carat, presented in a trill ion shaped cabochon. The gem measures 12.36 x 11.71 x 3.88 mm, and its triangular silhouette has been carefully faceted into a smooth cabochon to maximize the internal play of color. The material displays a multi color palette across its surface, with predominant cool blue and green flashes and secondary subtle violet and yellow tones when viewed under standard lighting. The opal is classified as crystal jelly type, exhibiting transparency sufficient to allow internal light transmission, and its overall visual behavior is characteristic of higher grade Australian material.

The opal was graded with a clarity of very slightly included, evaluated at eye level, and it has an intense color intensity accompanied by an excellent polish. No enhancement has been applied to this stone, it is presented in natural condition, and its origin is Australia. The cabochon cut emphasizes the gem s natural play of color by creating a gently domed surface that refracts light across the internal structure, and the piece s semi translucent body facilitates depth and movement of color as the viewing angle changes. At 3.88 mm depth the gem retains sufficient thickness for secure mounting, while the 12.36 by 11.71 mm footprint makes it suitable as a central element in small to medium sized jewelry settings.

From a practical perspective the opal s shape and optical properties make it well suited for a variety of fine jewelry applications, including pendants, rings, and stud earrings. The trillion profile offers a modern triangular aesthetic, and the cabochon finish reduces the risk of surface chipping while preserving maximum color vibrancy. For rings and pendants a bezel setting is recommended to protect the stone s edges, while a partial bezel or secure prong configuration may be considered for designs that require more exposed surface area to display color. Care instructions are straightforward, opals are sensitive to sudden changes in temperature and to prolonged exposure to harsh household chemicals, therefore cleaning with a soft cloth and mild soapy water is advised, and use of ultrasonic cleaners and steam should be avoided.

This Australian Crystal or Jelly Opal from The Natural Gemstone Company offers a balance of visual impact and practical durability, with a well executed cabochon cut, natural intense color, and a clarity grade that affirms its quality without the use of enhancements.
