Just went to JP n eclarity today.
Super ideal
0.527 F VS2 $3,800
0.51 E VS1 $4,150
Solasfera
0.53 E VS1 $5,300
Eclarity price is cheaper with similar specs. But no scope. N they claim that HCA is not recognised. How true is that?
HCA is a useful tool to reject out poorly cut diamond
only. It cannot be used a a decision maker to choose your diamond as there's still alot of other important factors it ignores. A diamond with a high HCA score confirms the diamond is poorly cut, indicating that the basic diamond proportion is poor.
High HCA score = reject
But... a low HCA score doesn't confirm that the diamond is good. You need to further confirm it with the scopes
Low HCA score = Check further with scopes
Eclarity does not carry Super Ideal Cuts. Their quality is different and won't be a fair comparison. Super Ideal cut is worth more.
JP just uploaded a video comparison of Super ideal cut and Ideal cut. Difference is quite obvious.. Even the Ideal cut diamond have a lower HCA score 0.9
Goes to show, HCA score is not everything.
The video beckslim posted is a good example.
Super Ideal cut diamond - HCA score 1.1
Ideal Cut diamond - HCA score 0.9
The Ideal cut have a lower HCA score but still pales in comparison against a Super Ideal Cut.
