5.32 Ct. Blue Flash Cabochon Moonstone from Ceylon (Sri Lanka)

This beautiful translucent 5.32 carat round blue flash moonstone, measuring 10.48 x 10.31 x 7.18 mm, offers a level of presence and optical play that outshines many of the more common, heavily included cabochons on the market. The cabochon cut maximizes the stone s ethereal adularescence, producing a clean blue flash that reads vividly against a light body color. With a clarity grade of very slightly included, evaluated at eye level, and an excellent polish, this Sri Lankan gem displays clarity and surface finish that are closer to fine aquamarines and sapphires than to the typical commercial moonstones. Unlike heat treated or otherwise enhanced stones, this moonstone is completely natural with no enhancement, and its Ceylon origin contributes to a purer sheen and translucency compared to many sources. At 5.32 carats the size is rare for such quality, offering superior value per carat when compared to smaller, lower grade moonstones that lack the same clean blue flash and polish, and The Natural Gemstone Company stands behind this piece as a top tier selection for discerning customers.

For a custom piece this moonstone pairs especially well with White Opal as a complementing accent due to the opal type White Opal s soft play of color, which creates a gentle contrast with the moonstone s blue adularescence. A halo of small brilliant cut diamonds will add sparkle and visual separation, elevating the moonstone s floating glow while protecting the cabochon shoulder in a bezel or half bezel setting. For a bolder, color rich look, deep blue sapphires or Australian blue sapphires will deepen the perceived blue flash, while pale aquamarines will harmonize with the stone s translucency for a serene tonal composition. Warm metals like 18k rose gold will coax peachy undertones from the moonstone, whereas platinum or white gold will create a crisp, icy presentation that emphasizes the blue flash and contrasts beautifully with White Opal flashes.

Design ideas that particularly suit this gem include a solitaire pendant with a diamond halo for everyday elegance, a three stone ring with sapphires flanking the central moonstone for classic symmetry, or paired drop earrings with matched White Opal accents for a sophisticated bridal set. Because this moonstone is large, well cut, and untreated, it offers a rare combination of beauty, durability in everyday jewelry, and long term value, and our team at The Natural Gemstone Company can help you visualize and create a custom piece that highlights these strengths.
