Some alloy mixes work better for casting and some are better for handcrafting like bending the prongs over fragile diamond corners. For those who live in remote areas far from fine jewelry stores, and for those with too little time to visit numerous jewelry stores in the quest for that perfect ring, it provides an opportunity to see what is available and what's new and exciting. The first disadvantage is the inability to see and compare the gemstones firsthand and to determine how well made the ring is or how it might compare to alternatives.
Explanation of Cut, Color and Clarity of This Diamond
Cut Quality Ideal cut refers to the angles and proportions of a diamond that satisfy very precise mathematical formulas. The result is that the the ideal cut diamond internally reflects most light from one mirror-like facet to another and disperse and reflect it through the top of the stone. This results in a display of brilliance and fire, thereby placing ideal-cut diamonds higher on the quality pyramid than deep or shallow-cut diamonds.
Color D color diamonds are absolutely colorless. D is the highest color grade. Natural diamonds of this color grade are extremely rare and expensive.
Clarity The stones of SI2 clarity have inclusions which are fairly easy to see under a loupe with 10X power magnification. Such inclusions may be visible to an unaided eye depending on their location. SI2 clarity diamonds of G or H color look nearly perfect when mounted. For those looking for near perfection these sure come close.
