We will manage the exit strategy in collaboration with our expert on behalf of our investors, ensuring the best possible outcome based on market conditions at the time. Depending on the prevailing market situation, the stone will be sold to a private buyer or offered as single lots at a gem-auction. An auction is considered if the price has developed to the point where the minimum bid matches the market value and there is high demand for works by the artist. Both options are carefully considered, and we will choose the one that maximizes the return for our investors.
Colored gemstones have long captivated investors and collectors alike, offering a unique blend of aesthetic beauty and financial security. Unlike traditional assets, their value is driven by rarity, cultural significance, and increasing global demand. The market for fine sapphires, sapphires,spinel and rubies has seen a steady appreciation, supported by limited supply and growing interest from emerging markets. Unlike diamonds, where synthetic alternatives pose a pricing challenge, top-tier natural colored gemstones maintain strong value retention due to their individuality and limited production. With auction records continuously being set, investing in premium colored gemstones is not just about appreciation—it’s about owning a tangible piece of history with enduring worth.
This 5.711-carat blue sapphire, sourced from Sri Lanka (Ceylon), is a standout specimen due to three key factors: its natural, untreated origin, its rare cornflower blue colour, and its high clarity and cut quality. Certified by Bellerophon, the gemstone confirms “no indication of heating” – a key value driver in the world of high-end sapphires.
The acquisition price of €17,260 (before fees) translates to ~€3,000/ct, positioning this stone at a 48% discount to comparable retail market benchmarks. Historical data shows that similar stones (based on carat weight, colour, and clarity) have consistently appreciated at an average CAGR of 10.6% over the last decade. Applying a conservative probability (60%) to this historical CAGR, the projected net ROI stands at 14.2% p.a. in the balanced scenario.
With growing demand for certified no-heat sapphires from reputable origins, market data and auction house trends further reinforce the asset’s return potential. The gem’s size and top-tier characteristics are particularly appealing to high-end collectors in Asia and Europe, where origin, treatment status, and colour saturation command significant premiums. Additionally, the use of B2B channels for acquisition ensures a healthy margin of safety for investors.
With certified origin, natural no-heat status, and a 48% entry discount, this blue sapphire offers intrinsic value and robust appreciation potential over a 5–7 year horizon. Its strong risk-return profile makes it an excellent addition to diversified long-term portfolios.
