Lab Grown Blue Zircon Colour #120 Gemstone - Stone Set & Cast-In-Place - OVAL

Product Description

Designed for both lost wax casting (cast-in-place) and traditional stone setting, these lab grown spinel-based gemstones are a versatile choice for jewellers working across multiple production methods. They can be set directly into wax prior to casting or used in finished settings such as claws, bezels, and custom mounts, making them suitable for both manufacturing and bench setting workflows.

With a Mohs hardness of approximately 8, spinel offers excellent toughness and resistance to thermal shock, making it well suited to investment casting environments as well as durable enough for everyday wear once set in jewellery.

These stones are produced using the flame fusion method and are spinel based, providing consistent structure, colour stability, and reliability for repeatable production work. Their uniform appearance makes them ideal for matched sets and commercial jewellery manufacturing.
