Diamond Price Assurance

Experience Diamond Bar

Rapaport Price List

The Rapaport Diamond Price list is NOT A WHOLESALE PRICE LIST for diamonds. It is an industry tool which is published every month to give a baseline price for dealers to trade well below. 99.9% of the diamonds in the market today trade at a wholesale price far below the Rapaport price. Many retail jewelers falsify this and tell you this is the absolute wholesale price. This is an unethical practice and not what we do at Spicer Greene Jewelers. We price our diamonds very competitively using our proprietary pricing tool, which places all of the information into your hands as the customer.

Ethical Diamond Practices

At Spicer Greene Jewelers, we can confidently say that our diamonds come from conflict free sources because we work directly with the diamond cutters and do not work through middle men. Additionally, of our diamonds have been vetted in an industry wide process known as the Kimberly process.

The Kimberley process is an international system established in 2003 to monitor the trade of rough diamonds. Spearheaded by the UN, this process requires all diamond shipments crossing international boarders be sent in a tamper resistant container with government validated certificate. All certificates are resistant to forgery and uniquely numbered to match each shipment.
