Sapphire · Facet Rough · Synthetic · #2 Pink · Split Boule

Bring your own gemstone designs to life with #2 Pink synthetic sapphire rough. This laboratory-grown pink corundum offers an appealing starting point for faceters who enjoy planning, cutting, and polishing their own colored gemstones.

Choose your rough to suit your project. Each boule has its own proportions, allowing you to compare the available pieces by photograph, weight, and dimensions before deciding which best accommodates your intended design. Longer pieces offer scope for sectioning into several cutting blanks, while the width and depth help determine the size and proportions of individual stones.

Cutting choices play an important role in the finished appearance. A deeper design and a thinner, more open cut can present the pink color differently, even when cut from the same boule. Lighting and the thickness of the rough also influence the color seen in photographs, so the uncut material serves as a guide rather than an exact preview of a finished gem.

With a Mohs hardness of 9, synthetic sapphire combines excellent scratch resistance with the ability to take a fine polish. It is suitable for both experienced cutters developing custom designs and hobby faceters building their skills with synthetic corundum.

Use the variation selector to explore the available boules. Every selection corresponds to a specific piece with its own reference number and product image. The piece pictured for your chosen variation is the one you will receive.
