| The
table is the large flat facet on the
crown or top of a diamond. The table
directly affects scintillation, or sparkle
in a diamond. The combination of table
size and crown angle governs the balance
between brilliance, flashes of white
light returning to the eye from within
the diamond, and dispersion, the play
of spectral colors seen by the eye created
by refracted light as it prisms through
a diamond's facets. |

GIA
has not established ideal table measurement
percentages for oval cut diamonds. But,
oval cut diamonds with table percentages
that measure below 62 percent or less deliver
exceptional brilliance. Oval diamonds within
this range are usually preferred for their
better balance of sparkle. Table measurements
that are within these ranges are considered
by Gemologists to have very fine table proportions.
Generally oval diamonds have table percentages
in the 52% to 62% range. Larger tables are
not as common in oval diamonds as they are
in other cuts. The brilliance of your diamond
depends on proper cutting. United Diamonds
selects only ideal to premium cut diamonds
to ensure that the diamond you choose will
be as brilliant as it is beautiful. A diamond
with these premium proportions will cost
more but its brilliance is well worth the
added investment. Our Certified Gemologist-Appraisers
will be happy to assist you in selecting
the most brilliant oval cut diamond possible.
