A Star cut diamond is a novelty fancy shape faceted into a five- or six-pointed star outline, brilliant-faceted across each point to keep the shape lively rather than flat. It's used as an accent or statement stone in custom jewelry rather than as a standard center-stone cut. Guru Diam stocks Star cut as IGI-certified lab-grown loose diamonds, with 30 pieces currently on hand.
What is a Star cut diamond used for?
A Star cut is a specialty fancy shape — five or six points radiating from a center, brilliant-faceted so each point still catches light instead of reading flat and graphic. It isn't a center-stone shape for a standard engagement ring; it's used as an accent stone in cluster settings, a statement stone in a custom piece built specifically around the shape, or a small detail stone in themed or distinctive jewelry design.
The points are also the reason so few wholesalers stock it as standing inventory. A sharp, symmetrical point on a diamond is inherently chip-prone, and a five- or six-point star has several of them to protect through cutting, setting, and daily wear. That difficulty is exactly why most of the trade treats Star cut as a one-off custom order rather than a shape worth holding real stock in.
Sourcing and custom work
Most Star cut demand comes through custom jewelry builds rather than off-the-shelf orders — a client wants a specific statement piece, and the star shape is chosen for that piece rather than pulled from a case. Lab-grown production makes that workable at the sourcing level: a cutter can produce a Star cut to spec (point count, size, symmetry) on demand instead of a buyer hunting for a rare loose stone that happens to already exist in the right size.
Guru Diam pairs 30 Star cut pieces on hand with made-to-order cutting for anything outside current stock, so a custom build isn't dependent on finding the exact stone by chance.
Certification and what to check
Guru Diam's Star cut inventory is IGI-certified, CVD-grown. Because the points are the highest-risk part of the cut, check facet symmetry and point condition under magnification before setting — a chipped point is far more visible and far harder to repair invisibly than damage on a rounded or beveled edge.

Frequently Asked Questions
What is a Star cut diamond used for? Star cut diamonds are used as accent or statement stones in custom jewelry — cluster settings, themed designs, or a centerpiece built specifically around the shape — rather than as a standard center stone for an engagement ring.
Why don't more wholesalers stock Star cut diamonds? The five or six points on a Star cut are chip-prone and difficult to cut and set cleanly, so most of the trade treats it as a one-off custom order rather than standing inventory.
Are Star cut diamonds certified? Yes. Guru Diam's Star cut inventory is CVD-grown and IGI-certified, with GIA certification available on request.
Can I get a Star cut diamond made to a specific size for a custom piece? Yes. Made-to-order cutting is available for sizes outside current on-hand stock, and custom jewelry (CAD to finished piece) runs 4–6 days from our New York and Los Angeles desks.
