When returning items containing a 0.75 carat gemstone or larger, Rasko Diamonds will require additional time to verify the diamond, in which case a refund will be approved upon positive verification. This process will require approximately 7 to 10 business days.

When returning items with delicate hand work, Rasko Diamonds will require additional time to verify the integrity of the craftsmanship, in which case a refund will be approved upon positive verification. This process will require approximately 7 to 10 business days.

Over time, fine jewellery can begin to look worn and tired. Dust, pollution and daily wear cloud the brilliance of gemstones. The surface of gold, platinum and silver jewellery can become dulled. Timeworn prongs and clasps can result in the loss of a stone or an entire piece of jewellery.

Professional cleanings are recommended as often as once a year. We encourage you to bring your Rasko Diamonds jewellery back to us for professional servicing. Our staff is knowledgeable and experienced in all aspects of jewellery care, including cleaning gemstones, restringing pearls and repairing clasps and earring backs.
