Each diamond we receive is graded and verified by at least two GIA Gemologists to provide accuracy and consistency.

We reject half to three quarters of all certified diamonds we grade due to misrepresented, inaccurate certifications, ensuring that stones we do sell meet our rigorous grading standards.

Due to 80 years of relationships built in the diamond industry and a triple-A credit rating, we are privy to extensive diamond memo programs that give our customers special access to diamonds for preview. This is in stark contrast to purchasing a diamond online. This gives our customers the luxury to hand-pick the perfect diamond that satisfies all their criteria before the purchase, not after.

Our long-standing relationships with our suppliers also benefit our customers by allowing Kubes to operate with lower margins on top of lower costs, giving us the ability to compete in price with even the largest online wholesalers.
