Review for Magic Diamond - Dillon Review For Magic Diamond - Dillon Google User Sep 6 '16 at 15:11 I recently came across Black Diamond Gourmet, while planning an event in Breckenridge, CO for Food Network Magazine. I spoke with Katrina, who was absolutely wonderful. She was accommodating to say the least, and very responsive! Their services are top-notch. I really enjoyed the interaction, overall, and will definitely be keeping this company in mind for future events! View full site to comment or like
