Thread: Coticule ID

Any guesses? It was sold to me as a La Grosse blanche from Ardennes yet I've yet to get it to turn brown and it has some la dressante and la veinette features. It's fast on slurry and moderately fast on water with a chalky, loud and fine sound of abrasion

I'd tend to believe the folks at Ardennes. This is their business, and they handle these stones all day. I've got a La Grosse Blanche, and it only develops spots over time if left in the sunlight.
Coticule identification is very tricky, IMHO ... and, most everyone wants their stone to be La Veinnette!

I've got two LV's and an LD. The LV's are both fast on slurry, and slow on water, with no feel, sound or sense of abrasion.

The vein is just that - the vein of rock that it's cut from. I would definitely trust them since they are the ones who quarried it.

Reminds me of when I busted the crystal on my Hamilton 'Masterpiece' wrist watch. Brought it to an ancient watch maker in North Arlington NJ. I said, "Is it a good watch ?"

He said, "Does it keep good time ? If it keeps good time it is a good watch."

Does it leave a good edge ? If it leaves a good edge I don't care which vein it came from.
