When you buy diamonds from Stuller, you can buy with confidence. We do not tolerate undisclosed synthetic diamonds in our inventory. In July 2014, we acquired the De Beers Automatic Melee Screening Device (AMS), which screens all diamonds 1.4mm+ for synthetics in accordance with De Beers’ protocols. We require all our loose diamond and diamond set jewelry suppliers to warrant that they are not supplying us with synthetics. For additional security, we further stipulate that our vendors screen all diamonds from .20+ carats for synthetics.
No Conflict Diamonds
We are committed to selling diamonds ethically and with integrity, giving you confidence in the diamonds you purchase. We believe it is completely unacceptable to tolerate conflict diamonds and/or human suffering in any way and we fully support the Kimberley process. Stuller Inc. offers this commitment to you. In turn, it can act as your commitment to your customers.
All rough and polished diamonds sold by Stuller Inc. comply with the Kimberley Process. The Kimberley Process ensures that rough diamonds are:
Exported and imported with a government validated Kimberly Process certificate stating the diamonds are conflict-free.
Transported between signatory countries in a sealed and tamper-proof container.
Sold with a statement from the seller (known as a warranty) on all invoices guaranteeing that the diamonds being sold are conflict-free.
