Complete Guide to Certified Fancy Shape Lab-Grown Diamonds
A fancy shape diamond refers to any diamond cut crafted outside the standard round brilliant parameters. Each fancy shape features a unique facet arrangement designed to interact with light in distinct ways, producing varying levels of fire, brilliance, and scintillation.
Choosing laboratory-grown fancy shape diamonds ensures you receive a gemstone with the exact optical, physical, and chemical composition of a mined diamond. Created under precise technological conditions using CVD and HPHT processes, these stones achieve identical hardness (10 on the Mohs scale) and refractive index ($2.42$). When paired with independent gemological certificates, buyers gain full assurance regarding the precise 4Cs – Cut, Color, Clarity, and Carat Weight. Understanding the various types of diamond cuts helps buyers select a stone that complements their hand shape, setting style, and personal taste.
Why Choose Certified Fancy Cut Diamonds in 2026?
Modern consumers consistently choose certified fancy shape lab diamonds for several key aesthetic, optical, and practical advantages:
Enhanced Visual Carat Presence & Finger Coverage
Elongated cuts like marquise, oval, and emerald shapes carry more of their weight across the top surface area (the table). As a result, selecting lab grown oval engagement rings or a lab grown marquise diamonds design provides a significantly larger face-up appearance on the finger compared to a traditional round diamond of equal carat weight.
Conflict-Free Origin & Uncompromising Value
Laboratory-created diamonds eliminate the environmental impact and ethical concerns associated with traditional mining. Furthermore, because fancy cuts optimize the natural shape of rough grown diamond crystals, production efficiency yields exceptional savings. This allows buyers to invest in larger carat sizes, such as a 3 carat oval diamond ring or a 4 carat emerald cut diamond ring, while staying well within their planned budget.
Understanding Certification: GIA vs. IGI Grading Standards
Independent laboratory certification is essential when purchasing fine jewelry. At Lepdo Diamonds, our inventory features stones graded by the world’s leading gemological institutes: the Gemological Institute of America (GIA) and the International Gemological Institute (IGI).
When evaluating GIA certified lab grown diamonds versus IGI certified lab grown diamonds, both institutions provide rigorous, unbiased verification of:
Laser Inscription: Direct matching of the report number inscribed on the diamond’s girdle for security and immediate verification.
Color Grade: Independent evaluation of colorlessness from D through Z.
Clarity Grade: Detailed mapping of internal inclusions and surface characteristics under high magnification.
Proportions & Polish: Complete assessment of facet symmetry, table percentage, and depth ratio.
Understanding the nuances when comparing igi vs gia reports ensures complete confidence that your diamond’s optical performance and authenticity are fully documented.

Frequently Asked Questions (FAQs)
Q1: What are the advantages of buying GIA certified lab grown diamonds in 2026?
Purchasing gia certified lab grown diamonds guarantees that your diamond has been independently tested and graded according to strict global gemological standards. A GIA report confirms physical specs, color grade, clarity, and lab-created origin with complete accuracy and international authority.
Q2: What is the main difference between IGI vs GIA certification for fancy cuts?
Both GIA and IGI are internationally recognized, highly reputable laboratories. GIA is widely regarded as the historical pioneer of diamond grading standards, while IGI is the largest and most established laboratory for comprehensive lab-grown diamond certification worldwide.
Q3: Which fancy shape lab diamond gives the best size for a 2 carat lab grown diamond ring price?
Elongated fancy cuts such as marquise, oval, and pear shapes deliver the largest visual surface area face-up. When evaluating a 2 carat lab grown diamond ring price, an oval or marquise cut will look visually larger on the finger than a 2-carat round brilliant diamond.
Q6: How do GIA and IGI verify that a diamond is lab grown?
GIA and IGI utilize advanced spectroscopic analysis (such as photoluminescence and infrared spectroscopy) to examine the growth structure and atomic characteristics of the crystal lattice. This allows gemologists to definitively distinguish lab-grown CVD or HPHT diamonds from earth-mined stones and issue specialized laboratory reports confirming their lab-created origin.
Q7: Is the report number laser-inscribed on every GIA and IGI certified lab diamond?
Yes. Every loose lab-grown diamond certified by GIA or IGI receives a microscopic laser inscription on its girdle (outer edge). This unique report number matches the physical certificate, allowing buyers to easily verify the stone’s authenticity and grading specs using a 10x jeweler’s loupe or micro-microscope.
