Mark Cartwright of Sapphire Sky Gem Lab in Fayetteville, Arkansas wrote the following letter to us about Perfect Diagram:
As a professional appraiser, my reports have to reflect the care and attention to detail my clients deserve and expect. With your Perfect Diagram software I can precisely match nearly every diamond my clients bring me and provide them with a clean, professional report. I can't imagine appraising diamonds without it. Great job Bill, and thanks again for the updates.
