18.19 Ct. Cabochon Moonstone from Ceylon (Sri Lanka)

One beautiful translucent oval grey moonstone is offered by The Natural Gemstone Company with a weight of 18.19 carats, dimensions of 16.03 by 11.42 by 13.43 millimeters, a classic cabochon cut, and a clarity grade of eye clean as evaluated at eye level. This specimen shows a medium color intensity and an excellent polish, it is fully natural with no enhancement, and it originates from Ceylon Sri Lanka. These specifics matter because many stones offered in the market are smaller, heavily included, heat treated, or dyed to compensate for weaker natural appearance. By presenting full measurements, cut style, clarity assessment, color strength, polish grade, and origin, The Natural Gemstone Company allows you to compare this moonstone side by side with alternatives, and to appreciate that this is a large, untreated, well finished gem that retains natural character and collector value.

When you compare this 18.19 carat Ceylon moonstone to typical commercial moonstones, the differences are immediately evident. Many mass market moonstones are under ten carats, often cut with shallow domes that mute the adularescence, and they frequently display surface polishing that hides scratches and abrasions. Others are sourced from less established localities or have undergone treatments that alter color and sellability. This grey moonstone with a tall cabochon profile benefits from its 13.43 millimeter height to enhance the ethereal light play that defines top quality moonstone. Its eye clean clarity stands out in a market where visible inclusions are common, and the absence of enhancement preserves both the stone s integrity and its long term value. In short, this is a seller grade gem that competes with higher priced pieces while offering a more honest natural presentation than many alternatives.

Beyond technical superiority, this moonstone offers distinct aesthetic advantages that make it unusually versatile for both contemporary and classic settings. The medium grey tone provides a soft neutral canvas that complements white gold, yellow gold, rose gold, and sterling silver, and it adapts well to both minimalist bezels and ornate vintage inspired mounts. The cabochon dome intensifies adularescence in changing light, producing a gentle sheen rather than a harsh flash, which is preferred for wearable fine jewelry. Compared to labradorite and certain synthetic options that display sharper flashes but less subtle shimmer, this moonstone maintains a serene glow that reads as refined and luxurious. Its substantial size and clean appearance also make it an excellent candidate for a statement ring, a pendant centerpiece, or a collector s study stone. For designers and collectors who value natural origin and untreated material, a Sri Lankan moonstone like this one carries provenance and aesthetic charm in equal measure.

At The Natural Gemstone Company we prioritize honest, informed comparison so you can choose the best gem for your purpose, whether that is a signature jewelry commission, an investment grade addition to a collection, or a meaningful heirloom. We can provide additional views under multiple lighting conditions to demonstrate the adularescence and polish, and we will disclose any relative strengths and limitations so you know how this gem will perform in a finished piece. Because it is untreated, eye clean, well proportioned, and sourced from Ceylon Sri Lanka, this 18.19 carat grey moonstone represents exceptional value compared with treated or lower clarity stones that may appear similar in photographs but disappoint in hand. If you prefer stones that are rare in size, honest in origin, and designed to wear beautifully for decades, this moonstone is an outstanding choice, and our team is ready to assist with sizing, setting recommendations, and secure shipping.
