One-of-a-Kind Aquamarine and Diamond Two-Tone Ring
Crafted in 14K white and yellow gold, this Croft & Stern original design features a 2.30ct bezel-set Alexander Kreis–cut aquamarine accented by 13=0.20ctw channel- and prong-set earth-mined round brilliant cut diamonds. Made in finger size 8.75 and finished with a bright polish.
Collector’s Note: Alexander Kreis–Cut Gem
An Alexander Kreis–cut gem is not factory perfection—it’s artistic intuition. Kreis cuts completely freeform, by hand, without a predetermined pattern. He studies the rough, listens to the material, and lets the gem dictate what it wants to become. No two gems are ever alike. Based in Germany near Idar-Oberstein—the historic heart of European gem cutting—the Kreis family has more than 500 years of continuous gem-cutting tradition, passing down skill and sensitivity to gems through generations. Instead of forcing symmetry or chasing carat weight, Alexander prioritizes optical movement, internal architecture, and the natural personality of the gem. Collectors seek his work because it’s the opposite of mass production: each piece is a conversation between cutter and gem, a one-of-a-kind sculpture in miniature.
