Every Red Box Diamond comes with a grading report from an independent lab or our team of GIA and AGS trained experts. Red Box graded diamonds are graded to GIA standards.


You will have proof positive identification, because each Red Box Diamond is laser inscribed with the unique number on its grading report.


Karla's Jewelry Showcase is committed to selling diamonds ethically and with integrity, so you feel confidence in the diamonds you purchase. We believe it is unacceptable to tolerate conflict diamonds and human suffering in any way. We support support the Kimberley process, because we offer it to you. The Kimberley Process ensures that rough diamonds are:

  • Exported/imported with a government validated Kimberley 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 their status.
  • This same warranty appears on all documents for Product Review/Conditional Sale items and on invoices for the products you purchase from Karla’s Jewelry Showcase.


You recieve full credit* for the Red Box Diamond when you trade it up for a higher priced Red Box Diamond in our active inventory.

*Diamond must be in original condition as when sold by Karla’s Jewelry Showcase.
