Pretty sure it's a purple urkle look alike, I wouldn't sell it as a purple urkle since there is no proof of linage, but it is a very nice coral for sure!
Just contacted the seller, and asked where she got it. She said it was sold to her on eBay as a Purple Urkle. She had no idea it was a collector piece! Such a cool find! I'm actually cutting a frag for her to have, since she sold it for less than $50.
It's a nice piece Brooks. Always nice to see a decent colony grown from a frag. I will say that if the buyer got it 2 years ago off of Ebay, the actual Purple Erkel was going for around $1000 / eye back then (and only a handful of people had it). So unless she (original buyer) is a hardcore chalice collector, I would say that it may be a look alike. A name is just a name, of course. But it matters to a lot of folks...lol.
All of that being said, it is a great looking chalice and we appreciate you sharing it with us. Any chance for a top down shot so we can get a better look at the colors?
