5.85 Ct. Cabochon Crystal/Jelly Opal from Australia

If you have been searching for a single stone that will end your quest for a memorable engagement ring or a rare centerpiece for a collector, this opal from The Natural Gemstone Company is designed to answer that need. Many clients tell us they want something with presence, character, and a story, and this piece delivers on all three counts. It weighs 5.85 carats, presenting a substantial and wearable mass of gem material that looks right at home on a ring, a pendant, or as the highlight of a collection. The oval shape and cabochon cut create a classic silhouette that flatters all hand sizes and jewelry proportions, while the semi transparent nature of this Crystal slash Jelly Opal invites light into the stone so you can enjoy complex play of color from every angle. If you want an opal that feels special, that reflects care and refinement, and that resolves the often frustrating search for the right material, this gem will likely end that search.

In practical and gemological terms this specimen stands out for its balanced combination of attributes. It measures 17.01 by 11.01 by 6.27 millimeters, dimensions that translate to a comfortable and noticeable face up size. The clarity is graded eye clean when evaluated at eye level, which means you will not see distracting inclusions with the unaided eye, preserving the visual impact of the fire and colors. The color intensity is medium and the polish is excellent, which accentuates the play of color without overstatement. This opal is heat treated, an enhancement that can intensify tone and stabilize certain materials, and it is important to know that the treatment has been disclosed. The origin is Australia, a provenance that is synonymous with quality opal specimens. As a Crystal slash Jelly Opal this stone offers semi transparency that allows internal color flashes to glow from within, producing vivid green and red flashes along with warm orange and yellow accents depending on the light and viewing angle. The cabochon dome was cut to optimize that internal light travel, giving lively slices of color as the piece moves.

Thinking about use and design, this opal is remarkably versatile and will satisfy a range of customer desires. For a customer seeking an engagement ring that stands apart from traditional diamond settings, the 5.85 carat size and the oval cabochon shape are both dramatic and elegant. A bezel setting will protect the stone and emphasize its soft outline, while a halo or open prong design can enhance the perceived size and add sparkle without overwhelming the opal itself. For collectors, the semi transparent character of a Crystal slash Jelly Opal is highly desirable because it demonstrates the internal structure and color play that make opals so prized. The excellent polish and eye clean clarity ensure that display under cabinet lighting or in a showroom will reveal bright, shifting color patches that are immediately captivating. Because the gem has been heat treated, we recommend thoughtful consideration of mounting and daily wear, opting for settings that protect from hard knocks and sudden thermal shocks, and choosing metals and design details that complement the opal rather than compete with it.

At The Natural Gemstone Company we understand that buying a gemstone is part emotional and part technical, and we stand beside this opal on both counts. We can provide additional photos, bespoke mounting suggestions, and guidance on care and insurance to help you move confidently from interest to ownership. Practical care for this heat treated Crystal slash Jelly Opal includes avoiding ultrasonic cleaners and steam cleaning, removing the piece for heavy activity, and storing it away from extreme heat and chemicals to preserve its polish and play of color. If you are designing an engagement ring we can advise on protective settings and matching accent diamonds or gemstones that will harmonize with the red, green, and warm tones in the stone. For collectors we can discuss documentation of origin and the nature of the enhancement, and provide secure shipping and packaging. Trust that this opal is a rare balance of beauty, size, and condition, and that accepting it into your jewelry or collection will be a decision that resolves the search for a meaningful, standout gem.
