 DIAMOND QUALITY-YOU GET WHAT YOU PAY FOR

Low quality synthetic diamonds

weaker crystals with irregular shape

shorter life & lower cutting rates

lower thermal stability

does not handle steel & hard aggregates well

jagged points that break causing faster wear & lower cutting & drilling performance

widely used in low priced dry products

Medium quality synthetic diamonds

good crystal strength & shape

good for sawing & drilling applications

good cutting speed

handles moderate steel & hard aggregate applications

High quality synthetic diamonds

strongest crystals 

lasts longer

withstands high temperatures

octahedral shape for increased tools life & faster cutting

high impact strength against steel & hard aggregate
