4.07 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This C.Dunaigre certified Blue 4.07 carat cushion shape blue sapphire from Ceylon Sri Lanka is a rare combination of size, clarity, and color, presented by The Natural Sapphire Company, transparent and precisely cut to dimensions of 8.78 x 8.23 x 5.61 mm. The faceted mixed brilliant cut and excellent polish maximize light return and scintillation, giving the stone a lively play of color that stands out even among premium Srilankan sapphires. With a vivid color intensity that captures the classic Ceylon blue, and a clarity grade of very very slightly included evaluated at eye level, this sapphire offers an exceptionally clean appearance to the naked eye, while retaining the natural character connoisseurs value. Compared with other market options, this gem outperforms many commercial sapphires that are smaller, more included, or lack the balanced saturation and tone that make a sapphire read as vivid without appearing too dark. Heat treated enhancement is industry standard, fully stable, and done to elevate the stone to its ideal visual potential, making it superior in value and consistency to untreated stones whose color can be uneven or overly muted, and to lower quality alternatives such as topaz or aquamarine which cannot match sapphire hardness or depth of color.

Beyond its visual virtues, this 4.07 carat Ceylon cushion sapphire is especially suited for daily wear, a key advantage for those seeking a practical and beautiful center stone. Sapphires rate nine on the Mohs scale, second only to diamonds for natural gemstones commonly set in jewelry, which means they resist scratches from daily contact far better than stones like opal, tanzanite, or quartz. The mixed brilliant facet arrangement and excellent polish not only enhance brilliance, they also minimize wear and tear by producing fewer shallow facet edges that chip easily. The combination of hardness and toughness inherent to sapphire makes this gem ideal for engagement rings, everyday pendants, and bracelets, offering long term stability and enduring beauty without demanding excessive special care. When you choose this C.Dunaigre certified Blue cushion sapphire from The Natural Sapphire Company, you are selecting a gem that balances rarity, visual impact, and the strength required for regular use, delivering superior value and peace of mind compared with many other gems on the market.
