If you’re looking for the best lab diamonds for sale in Canada, consider these four factors:
Excellent cut.
When it comes to a lab-created diamond, the cut will likely be better than what you can get from a mined diamond because of the way the stones are made. As long as your chosen lab diamond has been expertly faceted, it should have excellent symmetry and sparkle that outshines mined diamonds with poorer cuts.
High color grade.
In order to look natural and beautiful, your purchased lab diamond must also have a high color grade—a rating based on how much a stone absorbs light across its surface area. A lower color grade means less absorption and thus more light reflected back at you (and others), making your gem look whiter and more brilliant than if it was given a higher grade like “G” or “H” on its certification report card (if such reports are available). So make sure yours is rated below “D.”
High clarity grade.
While we’re talking about certifications here, don’t forget about clarity! Lab-created diamonds usually have fewer internal flaws than their mined counterparts do (because they’re grown rather than extracted), so they’ll almost always score better when tested under magnification by an independent inspector during grading processes like those done at GIA Laboratories or IGI USA Ltd., who often verify whether each stone meets industry standards set forth by their respective organizations before issuing certificates of authenticity upon completion of inspection processes; most labs perform both visual checks plus additional tests depending on how much money customers want to invest in this step alone versus other steps taken together throughout production cycles running anywhere between three months up until two years depending upon which company makes them–and whether customers choose custom cuts/designs versus standard ones already available online prior.
