Description from the seller
Royal Antwerp Gem
Natural Greenish-Blue Sapphire 3.04 ct
Oval Cut | GRS Swiss Lab Certified | Antwerp
DESCRIPTION
A beautiful natural greenish-blue sapphire from Madagascar displaying an attractive combination of blue and green color tones and an elegant oval brilliant/step cut.
This gemstone weighs 3.04 carats and measures approximately 10.18 x 8.00 x 4.25 mm. The oval cut enhances brilliance and light reflection while maintaining balanced proportions that suit fine jewelry settings.
Greenish-blue sapphires are appreciated for their distinctive combination of blue and green hues, creating an elegant appearance that differs from traditional blue sapphires. Madagascar is a well-known source of natural sapphires, producing gemstones in a wide variety of attractive colors.
The gemstone features an appealing greenish-blue color and an elegant oval shape, making it suitable for rings, pendants, and custom jewelry creations. Its weight of over 3 carats also makes it an interesting choice for gemstone collectors.
Photographs are taken using professional macro lighting to reveal details similar to viewing through a jeweler’s loupe. Due to magnification and lighting conditions, inclusions may appear more visible in images than under normal viewing conditions.
