Hongkong Jingcan Crystal Craft Limited is one of the leading manufacturers and suppliers of lab created oval diamond in China, featured by quality products and low price. If you're going to wholesale the newest lab created oval diamond made in China, welcome to get quotation from our factory. Customized orders are welcome.
The oval-cut lab-grown diamond has become a highly sought-after choice for jewelry designers and wholesalers, celebrated for its graceful elliptical silhouette. This elongated shape is a designer's secret weapon, as it beautifully elongates the wearer's finger and makes the finished jewelry appear significantly larger and more delicate than its actual carat weight suggests.
Our IGI-certified oval loose diamonds are available in a premium D color grade, delivering that crisp, icy-white appearance that high-end clients desire. To accommodate diverse design budgets and cost-control strategies, we offer a versatile range of carat weights from 1ct up to 5ct, with clarity options spanning VS2, VS1, and VVS1. Every stone is accompanied by an official IGI certificate, ensuring complete parameter verification and quality tracing. Coupled with an excellent cut, these diamonds guarantee stable, attractive light reflection and maximum brilliance.
These ethically sourced oval diamonds are incredibly versatile, perfect for crafting breathtaking engagement rings, classic solitaire pendants, and elegant dangle earrings. Offering the exact same visual beauty as natural oval diamonds but with a distinct price advantage, they are an ideal raw material for bulk wholesale, custom bridal collections, and gem-stock preparation. For fine jewelry businesses, they represent a reliable, high-margin choice that satisfies the growing consumer demand for sustainable luxury.

Frequently Asked Questions (FAQ)
Q1: Why are oval-cut diamonds so popular for engagement rings?
The oval cut offers the best of both worlds: the brilliant sparkle of a round diamond combined with a unique, elongated shape. Because of their extended silhouette, oval diamonds create an optical illusion that makes the stone look larger and the wearer's fingers appear longer and more slender. This flattering effect makes them a top choice for modern brides.
Q2: What is the "bow-tie effect" in oval diamonds, and how do you prevent it?
The bow-tie effect is a dark, shadowy area that stretches across the center of elongated step or brilliant-cut diamonds, resembling a man's bow tie. It is caused by light leakage due to the cutting angles. Our premium oval diamonds are expertly cut to minimize this effect, ensuring a bright, even light reflection across the entire stone without distracting dark shadows.
Q3: How does a VS2 clarity grade perform in an oval cut?
Oval diamonds are generally excellent at hiding inclusions because their complex, brilliant facet patterns create a lot of sparkle and light distortion. A VS2 clarity grade is often considered the "sweet spot" for oval cuts, as it is typically 100% eye-clean to the naked eye while offering significant cost savings compared to VVS or flawless grades.
Q4: Are lab-grown oval diamonds physically identical to natural ones?
Yes, absolutely. Lab-grown diamonds are pure crystallized carbon, sharing the exact same chemical, physical, and optical properties as mined diamonds. The only difference is their origin. An IGI-certified lab-grown oval diamond will test positive as a real diamond on standard diamond testers and possess the same Mohs hardness of 10, making it perfectly suited for everyday wear.
Q5: Do you offer matched pairs or calibrated sizes for earrings and pendants?
Yes, we specialize in providing calibrated loose diamonds for jewelry manufacturers. Whether you need perfectly matched pairs for dangle earrings or specific calibrated sizes for solitaire pendants, our IGI-certified inventory ensures consistent D color and precise measurements, streamlining your production process and guaranteeing symmetrical, high-quality finished pieces.
