We are a family owned and operated business since 1968.


Originally founded by our late father, Nathan Oami, solely as a diamond cutting venture in the late 60’s, we built upon our extensive understanding of diamond assaying and client needs to evolve into what we are today - a comprehensive and competitive buyer, seller and appraiser of complete estates, specializing in antique and fine jewelry as well as a loose diamonds and gemstones.


With our training and affiliation with experts in the field such as GIA and our large knowledge base, we utilize high standards and cutting edge technology to identify and evaluate estate pieces and stones to ensure our clients get the highest prices the market will allow. As we have a diamond cutting lab in house, we are also able to offer the most competitive prices for broken, chipped, abraised and worn stones.


We proudly possess a strong international reputation amongst our vast network of clients, partners, colleagues and vendors built on honesty, integrity, wholesale pricing and a keen sensitivity to our clienteles’ satisfaction.
