Hi Everyone!
I feel fortunate that I was able to find such a valuable resource such as pricescope - your forum has provided great insight due to the many diamond experts that frequent this online community.
Over this entire research process, I have turned from someone who thought that diamonds were just sparkly pieces of carbon to someone who has a decent (I hope) understanding of the dynamics of light and its interaction with the proportions in a diamond.
I’m currently in the process of buying a pre-owned stone and I am concerned about head-obstruction. The pavilion angle is 40.4 degrees
and from what I’ve gathered from various posts in this forum, there are head obstruction issues with this pavilion angle in certain crown angle combinations.
Now this stone has a steep crown angle at 36, does anyone know if a steep crown could lessen the degree of obstruction?
I plan to meet with the seller to verify that there are no head obstruction issues and that it is eye-clean. If everything goes to
according to plan, I fully intend on having an appraiser review it for authenticity and damage as it has been worn for a little less than a
year.
The private seller (a doctor in Toronto) is posting it for CAD 8700 with some negotiating room. He said he purchased it from distributor called Corona.
What does everyone think of this stone? Are there any additional steps when purchasing a pre-owned stone that I should be aware of?
I appreciate and welcome any feedback. Thanks in advance.

He likely paid much more, and likely has an "appraisal" stating it is worth much more, but that does not mean you should pay what he is asking since you could get a similar stone brand new online for the same price he is asking. I would offer about 50% of the online retail price, if you really like it and it checks out with the appraiser. Maaaybe 70% of online retail. But it is very hard to sell diamonds on the secondary market, so take advantage of that
