Frequently Asked Questions
What makes trillion cut lab grown diamonds unique? +
Trillion (or trilliant) cut diamonds have a triangular shape with three equal sides,
often featuring slightly curved or straight edges and brilliant-style facets.
They deliver bold, modern sparkle and a very distinctive geometric look that stands out
in both rings and earrings.
Do trillion cut diamonds look larger than other shapes of the same carat weight? +
Yes. Because of their shallow depth and wide, triangular face-up area, trillion cuts often
appear larger than many other shapes of the same carat weight, offering excellent finger
and ear coverage for the size.
Do trillion cut lab grown diamonds sparkle as much as round or princess cuts? +
Trillion cuts use brilliant-style faceting, so they offer strong sparkle and lively fire,
especially at the edges. The look is different from a round—more edgy and directional—but
still very bright and eye-catching when well-cut.
Are the pointed corners of trillion cut diamonds prone to chipping? +
Yes, the three points are the most delicate parts of a trillion diamond. A secure setting
with protective V-prongs or bezel-style coverage at each corner is essential to reduce the
risk of chipping, especially for rings worn daily.
What is the ideal proportion or shape for trillion cut lab grown diamonds? +
Most buyers prefer trillions that are close to equilateral, with sides of similar length
and balanced angles. Well-cut trillions should not look too long and narrow or overly flat,
and they should show even brightness across the stone.
Do trillion cut diamonds show inclusions more than other shapes? +
Trillion cuts can reveal inclusions in the center due to their shallow depth and wide table,
but their intense edge sparkle helps disguise minor imperfections. Many buyers choose
VVS–VS clarity for center stones and are comfortable with VS–SI for side stones,
especially in lab grown diamonds.
Which settings look best with trillion cut lab grown diamonds? +
Trillion diamonds look stunning as side stones next to round, oval, or emerald centers,
and they also make striking solitaire center stones in modern, bezel, or three-prong settings.
They are also popular in stud earrings and contemporary pendant designs.
Do trillion cut diamonds show color easily, and which color grades are recommended? +
Because of their shallow cut, trillions can show a bit of color near the points and edges.
Many buyers prefer D–H color to keep the diamond looking bright and white, particularly
in white metal settings like platinum or white gold.
Are trillion cut lab grown diamonds comfortable for everyday wear in rings? +
Yes, with the right setting. When the corners are well-protected and the diamond sits
low enough in the ring, trillions can be worn daily. Their shape is more exposed than
some other cuts, so choosing a secure design is important.
Are trillion cut lab grown diamonds certified by IGI or GIA, and do they come in many sizes? +
Yes. Trillion cut lab grown diamonds can be certified by IGI, GIA, and other reputable
laboratories. They are available from small accent sizes to larger center stones, making
them suitable for engagement rings, side stones, earrings, and unique custom pieces.
