Chelsea and Synthetic Emerald Filters Made Easy: The "RIGHT-WAY" Guide to Using Gem Identification Tools (The Antoinette Matlins "RIGHT-WAY" Series to Using Gem Identification Tools)

I have used the Chelsea filter before but she explains the little instructions that make the accuracy stick❗ Correct lighting, correct positioning to get the accurate reading people are respected for. Builds business confidence when your correct.

Excellent book a must have for gem identification in my opinion the way its written makes it so easy to understand the charts are invaluable a must have and I have now purchased all of her guidebooks

Good info

Very helpful and nice hand book

Good synopsis of the use and limitations of a Chelsea filter, would have liked more extensive listing and details of what to expect to see when looking at gemstones through it, or best equipment to accompany with other tests.

Not what I expected but probably my own fault for not checking reviews
