For Technical Q&A, see here: Whiteflash ACA Classic & New Line: Questions & Answers
There are two finishing styles used to brillianteer the girdle facets on Whiteflash ACA Hearts & Arrows diamonds. That is why you will sometimes hear them differentiated as Classic and New Line. To untrained observers the tangible differences are very slight. All Whiteflash ACA are cut with Visual Balance™ as a priority. In terms of overall performance they stand side by side. The untrained eye sees either as a dazzling diamond.
Of course, after studying, handling and playing with top performing diamonds one begins to make distinctions, much like a refined palate learns to sense differences in fine wines. When Whiteflash clients view the styles together, they can see slight character differences once we elaborate on them. They also confirm that both styles are at equal levels of beauty, and are perfectly happy with either.
Which is Which?
The style of cutting may be identified in the ideal-scope photograph provided for every diamond we sell:
ACA Classic are characterized by symmetrical points of contrast leakage along the girdle and at junctions where the upper girdle and star facets meet.
Whiteflash ACA New Line are characterized by minimal light leakage in their ideal-scope photos.
The Visual Difference: Brillianteering
All Whiteflash ACA are cut with Visual Balance™ as a priority. This means we have maximized traditional qualities of brilliance and fire through the broadest possible range of lighting conditions, so the differences are observable only in the character of our diamonds’ scintillation and contrast. These differences, while subtle, are intriguing.
ACA Classic have pronounced contrast, resulting in a fast, sharp, on-off quality to the scintillation.
This style represent a marriage of modern Hearts & Arrows patterning with traditional diamond finishing techniques. The upper girdle, crown and star facets are brillianteered with a balanced spread in their angular relationships. Light returning to the viewer’s eye is splintered along these symmetrical paths and junctions at different angles, giving the intense, on-off look to the scintillation. The sharper dispersion is beautiful in all illumination scenarios, with small pinpoint flashes that are especially intense in bright light conditions.
Whiteflash ACA New Line have a robust, broadfire scintillation that is described as fluid and colorful.
With New Line the brillianteer uses a polishing strategy called painting, where the crown facets are lightly run on the wheel from star to girdle rather than girdle to star. This approach results in upper girdle facet angles finished closer to the adjacent main crown and star angles. Optimized light return flows easily across these closely matched angles, creating large, broadfire scintillation, described as fluid and colorful. The spectral colors erupting from these diamonds are especially notable in soft light conditions like candlelight, when your pupils are dilated.
All told, the number of buyers who concern themselves with the differences is a tiny percentage of diamond enthusiasts. Classic and New Line Whiteflash ACA are at equal levels of craftsmanship and beauty.
We encourage everyone to have one of each.
