Natural Blue Sapphire 1.70 Ct — Twilight Sovereign
From
$375.00
This exquisite Natural Blue Sapphire weighs 1.70 carats and displays a majestic blue hue prized since antiquity as the colour of royalty and heaven. Sourced from the renowned gem mines of Sri Lanka, this stone reflects the island's world-famous reputation for producing fine-quality gemstones with exceptional brilliance and clarity.
Expertly fashioned in an elegant oval cut, measuring 7.70 × 5.40 × 4.60 mm, the stone is proportioned to enhance light return and maximize sparkle. With a clarity grade of Eye Clean (VS), this gem shows outstanding transparency and lively brilliance throughout.
Importantly, this gemstone is completely untreated, meaning its beautiful pale blue color is entirely natural. Untreated Ceylon stones are increasingly rare and command premium demand in the international market. This stone is the classic Ceylon sapphire — the stone against which all other blue gems are measured.
This gemstone is ideal for fine jewelry, bespoke collector pieces, or investment. Its rarity, clarity, and natural origin make it a refined investment-grade stone.
