Oecler custom-cuts lab-grown diamonds into almost any shape, including kite and kitty cuts, and each custom shape is cut to order. This guide covers how a custom outline is planned, how kite and kitty examples look in practice, how pointed shapes can be set, and what to expect on lead time, final sale, metals and certificates when you order from Oecler. Lab-grown colored gemstones are sold in standard cuts only; they are not custom-cut into fancy shapes.
What is a custom-cut lab-grown diamond?
A custom-cut lab-grown diamond is a laboratory-grown diamond faceted to an outline and facet plan you and the cutter agree on before work starts, rather than a stock round, oval, cushion or other standard fancy shape. Under the U.S. FTC Jewelry Guides, sellers must clearly disclose that a laboratory-created stone is not mined, for example by placing “laboratory-grown” or “lab-grown” right before the gem name (FTC). Oecler describes every stone it sells as lab-grown. Lab-grown colored gemstones at Oecler are offered in standard cuts only; they are not custom-cut into fancy shapes, because hardness and cutting methods differ from diamonds.
GIA explains that laboratory-grown diamonds have essentially the same chemical composition, crystal structure, and optical and physical properties as diamonds found in nature (GIA 4Cs). A custom-cut lab-grown diamond from Oecler is a newly grown and newly cut stone. It is not an antique, even when the outline is unusual or the design is inspired by vintage jewelry.
“Almost any shape” at Oecler means the cutter can work from a customer sketch or reference for outlines such as kite, kitty cut (listed as cat-face cut on the product page), shield, letter forms and other non-standard silhouettes, subject to what the rough will safely allow. It does not mean every sketch is equally efficient in weight retention or equally easy to set. Agreeing the outline early avoids surprises later, because custom stones are final sale once cutting is underway.
How kite and kitty cuts are planned
Three decisions matter before a custom shape is cut: the outline, the facet style and the setting plan.
Outline. Send a clear sketch or reference image with a rough length-to-width ratio. A kite cut is a diamond- or kite-shaped outline with pointed or near-pointed ends; a kitty cut is a figurative outline that reads as a cat’s face face-up (the product page also calls this a cat-face cut). Oecler shows working examples as a 4.406 ct fancy brown kite-shaped lab-grown diamond and a 1.162 ct D–E kitty cut lab-grown diamond.
Facet style. Brilliant-style faceting aims for sparkle and scintillation; a step-cut plan aims for broader flashes and a “hall of mirrors” look that GIA associates with step-cut shapes such as emerald cuts (GIA 4Cs). The same outline can look very different under the two approaches, so pick the look before cutting starts.
Setting plan. Pointed or sharp corners need a setting that protects them in daily wear. Agree whether the stone will be worn as a loose collector piece, a pendant, earrings or a ring before the final proportions are locked, because head height and point protection affect how much material the cutter can leave at the tips.
Marie, the founder of Oecler, sources the lab-grown stones herself, directly at the origin in Henan. That sourcing step comes before the custom cutting plan: the available rough or preform has to support the outline you want.
How pointed custom shapes are set
Pointed fancy shapes can be prong-set or bezel-set to protect the points, and Oecler offers both. GIA’s shape guidance for pointed styles such as pear and princess cuts likewise emphasizes a secure setting, such as a prong or bezel setting, to protect vulnerable tips and corners (GIA 4Cs).
When the custom-cut lab-grown diamond is set into jewelry, Oecler uses solid 14K or 18K yellow gold, solid 14K or 18K white gold, or platinum. Made-to-order pieces take 3–5 weeks to make, then 7–10 days in transit, with free DDP shipping to the US, UK and Australia. Shoppers who want to explore settings online can start from the engagement rings category, the custom page or the ring customizer.
How to order a custom shape from Oecler
- Share the outline. Email or WhatsApp a sketch, CAD still or photo reference with approximate length-to-width and the intended use (ring, pendant, loose stone).
- Confirm facet style and carat target. Brilliant-style vs step-cut, and whether weight or outline fidelity matters more if the rough forces a trade-off.
- Confirm the setting. Prong or bezel for pointed tips; metal choice among solid 14K or 18K yellow or white gold or platinum if the piece will be mounted.
- Sign off before cutting. Loose stones and custom pieces at Oecler are final sale, so the outline should be approved before the cutter starts.
- Decide on a report when you order. Certificates are available on request; nothing ships with a certificate by default (details below).

Certificates for custom-cut stones (on request)
Oecler does not include a certificate by default. On request:
- A loose lab-grown diamond can get an IGI certificate (grading report) — about 20 extra days on top of normal production time, $50.
- Finished jewelry can get an NGTC report — about 3 days, free.
- A loose lab-grown colored gemstone can get an AGL report — about 3 days, free.
Shoppers usually say “certificate”; labs often describe the document as a grading report. Ask for the report when you place the order if you want one, especially because custom and loose pieces are final sale.
