The centerpiece of this stunning ring is an approximately 4.37 carat oval cut natural yellow sapphire—it's bright yellow and looks like a frozen drop of the tangiest lemonade you've ever had! Set in a diamond accented crown that sits atop a wide diamond studded band, both the sapphire and the accent diamonds are of an exceptional quality. To boot, it's made of a buttery yellow 18 karat gold.

Hammerman Bros. (still operating today as "Hammerman Jewels" in New York) is a storied American design house known for inventing the watch bracelet in the 1940s!

This yellow sapphire is accompanied by a GIA Sapphire Origin Report and the ring comes with an independent GIA Graduate Gemologist's appraisal dated April 8, 2025.

Rare & Unusual

How to Wear with Care

Jewelry is meant to be worn, but it's also an expensive ornament. Here are a few suggestions to extend the life of your jewelry:

  • We encourage you to have your jewelry checked and cleaned by us or another trusted jeweler every six months.
  • You should remove your rings before swimming or performing any household cleaning, as harsh chemicals can interact with precious metals and permanently damage some stones.
  • Generally, we suggest that you do not wear your jewelry to the gym, in the shower, at the pool, or while sleeping.

We do not sell what we cannot service. Should an issue arise, please get in touch. We offer an extensive range of repair services and are here to help!
