Ruby, sapphire, emerald – the “big three” of gemstones are highly sought after and can command absolute premium prices. Carlo Mutschler, head of our goldsmith’s department, explains where the most valuable stones come from and what quality criteria are important.
Did you know that gemstones are often of superior quality to diamonds and are also found more rarely? Incidentally, after our two-hour seminar, we gave away a blue sapphire worth around CHF 1,500 in a prize draw and served our guests a glass of champagne. This course takes place regularly. It is free of charge for our clients and costs CHF 60 for outside guests. Are you interested? Then send us a message.
