We handle the exit strategy for our investors in collaboration with our expert, ensuring we achieve the best possible outcome based on market conditions. Depending on the market, the stone will either be sold to a private buyer or offered as a single lot at a gemstone auction. An auction is considered if the price has evolved such that the reserve matches market value and there is high demand for the artist’s works. Both options are carefully assessed, and we select the one that maximizes returns for our investors.
Colored gemstones have long captivated investors and collectors alike, offering a unique blend of aesthetic beauty and financial resilience. Unlike traditional assets, their value is driven by rarity, cultural significance, and rising global demand. The market for high-quality emeralds, sapphires, spinels, and rubies has experienced steady appreciation, supported by limited supply and growing interest from emerging markets. In contrast to diamonds, where synthetic alternatives challenge pricing, high-quality natural colored gemstones retain significant value due to their individuality and limited production. With auction records continually being set, investing in high-quality colored gemstones is not only about appreciation but also about owning a tangible piece of history with enduring value.
The intensely blue-green sapphire stands out as a highly sought-after investment because it combines a rare mix of size, unheated status, and intense coloration. At 8,600 carats, it ranks among the larger sapphires, especially given that most stones over 5 carats are already genuinely rare. The fact that it shows no signs of heating significantly increases its market value, as naturally vibrant, unheated sapphires are estimated to be 75 to 100% more valuable than heated stones.
Certified by Bellerophon, this cushion-cut gemstone originates from West Africa and combines exceptional provenance with technical quality. Its eye-clean clarity and optimal proportions make it even more attractive to collectors seeking flawless, investment-grade stones.
The purchase price of €19,910 reflects a 27% discount versus comparable retail prices and offers a substantial margin of safety. Current benchmarks from premium dealers confirm that comparable unheated sapphires in this weight class trade at significantly higher prices, validating the price advantage.
Furthermore, the sapphire market continues to show steady long-term appreciation, with a historical compound annual growth rate (CAGR) of 11.5% (2010–2023). Combined with an expected balanced return of 13.7% p.a. and a projected optimistic outcome of 19.1% p.a., this investment benefits both from downside protection and considerable growth potential.
Its rarity, together with robust collector demand and limited supply of high-grade stones, makes this sapphire an attractive acquisition over a 5- to 7-year period, supported by its uniqueness and certified origin.
The intensely blue-green sapphire offers a rare opportunity to acquire a high-quality gemstone below market value. Backed by certification, historical performance data, and limited availability, it combines low volatility, long-term growth prospects, and strong collector demand, making it an attractive addition to a diversified alternative-assets portfolio.
