1.70 Ct. Blue Sapphire from Australia

This transparent 1.70 carat oval shape blue sapphire from The Natural Sapphire Company measures 8.87 by 6.75 by 3.36 mm, and it stands out for combining classic proportions with modern brilliance. The mixed brilliant cut brings a lively play of light across the surface while preserving weight and depth, and the excellent polish ensures strong facet contrast and refined sparkle. With a clarity grade of very slightly included evaluated at eye level the gem shows only minimal natural character that does not detract from its visual appeal. The dark color intensity delivers a rich, inky blue that reads as timeless and versatile for an engagement ring, and the stone has been responsibly heat treated to enhance its color, a standard and stable enhancement widely accepted in fine jewelry. Origin Australia gives this sapphire a distinct personality compared with lighter Sri Lankan material or the velvety tones of historic Kashmir gems, offering a deeper, more dramatic hue that photographs beautifully and makes a bold statement on the hand.

When compared with other engagement center stone options, this sapphire offers several advantages in quality, value, and uniqueness. Versus a comparable sized diamond the sapphire provides immediate color and presence at a more accessible price per carat, while retaining exceptional durability thanks to sapphire hardness near the top of the scale, making it perfectly suited for daily wear. Versus other natural sapphires on the market this Australian gem combines a desirable dark saturation with a mixed brilliant cut that maximizes scintillation without sacrificing depth, and its very slightly included clarity offers an attractive balance between eye appeal and natural origin. Against synthetic or heavily treated alternatives this sapphire offers authentic natural character and traceability when purchased through The Natural Sapphire Company, where each gem is evaluated by experienced gemmologists and presented with transparent information about treatment and origin. For an engagement ring the result is a stone that is distinctive, enduring, and elegant, offering the emotional resonance of a colored gem with the reliability and refinement expected in fine jewelry.
