🔥 Why This Stone Is a Powerful Investment

💠 Huge aquamarines are skyrocketing in demand.
Once you cross the 15ct mark, stones become highly collectible — at 21.74ct, this one sits firmly in the “investment grade” category.

💠 They’re not making more of these.
Large, clean natural beryl of this size is now incredibly scarce. This is the kind of stone buyers look back on and say, “I wish I’d grabbed it when I had the chance.”

💠 Wearable and investable.
It’s bright, icy, clean, and elegant — perfect for a future showstopper ring or to keep as a loose collector’s stone.

💠 Timeless appeal.
Aquamarine never goes out of fashion. It’s a heritage gemstone with long-term value, not a trend that fades after a season.

💠 Favoured by luxury houses.
Brands like Bulgari, Cartier, and Oscar Heyman consistently use large aquamarines, keeping global demand elevated — especially for stones over 20ct.
