The Allure of Sapphires: Nature’s Most Enchanting Gemstone

Oval-cut sapphire gemstone with deep blue facets supplied by Sico International, London

When it comes to rare and precious gemstones, sapphires have long captivated royalty, collectors, and connoisseurs alike. At Sico International, based in London’s prestigious Hatton Garden, sapphires are not just a speciality — they’re a passion. With over 26 years of global experience, and sourcing offices in Colombo, Sri Lanka, and Chantaburi, Thailand, we offer clients access to some of the rarest and most valuable natural sapphires in the world.

Why Choose a Sapphire?

Sapphires are famed for their rich blue hues, but their allure goes far beyond a single colour. These gemstones come in a rainbow of shades — from velvety royal blue to vivid pink, orange, yellow, and even the elusive Padparadscha, a rare pink-orange variety prized by collectors. The unique brilliance and durability of sapphires make them ideal for both high-end jewellery and long-term investment.

Natural. Untreated. Exceptional.

In a world where many sapphires are heat-treated to enhance colour and clarity, natural, untreated sapphires are increasingly rare — and highly sought after. At Sico International, we focus exclusively on natural stones, many of which are unheated, preserving their purity and ensuring they retain maximum value.

Each sapphire in our collection is hand-selected and independently certified by leading gemological laboratories to guarantee origin, authenticity, and quality.

Our Global Advantage

With sourcing offices in Sri Lanka — home to some of the most celebrated sapphires in history — and Thailand, a major trading centre, we are uniquely positioned to procure stones that never reach the mainstream market. This international presence allows us to act quickly, negotiate directly with miners and dealers, and offer our clients first access to exceptional stones.

Investment Potential of Fine Sapphires

In recent years, the value of natural sapphires has steadily increased, especially for stones with no thermal enhancement and exceptional provenance. Fine sapphires are now recognised not only for their beauty but also as secure and appreciating assets — often outperforming more traditional investments.

Whether you're acquiring a sapphire for a bespoke jewellery creation or building a portfolio of rare gems, Sico International ensures every stone we offer meets the highest standards of rarity, quality, and certification.

Custom Sourcing for Unique Requests

Looking for a Kashmir sapphire with velvety depth? A Ceylon sapphire with unmatched brilliance? Or a rare, investment-grade Padparadscha?
