Solitaire, halo, three-stone, pavé. 14k, 18k, platinum.
Hand-set in Sydney. Insured worldwide shipping. Lifetime warranty.
Weight, not size. A well-cut 1.5ct faces up larger than a poorly cut 2ct. We list dimensions on every stone.
D (colorless) through H (near-colorless). All Celestyn stones D-H grade. Anything below H shows warmth.
FL (flawless) through VS2. Inclusions invisible to the naked eye at 10x magnification. We never sell below VS2.
The only C controlled by human craft. Ideal and Excellent cuts only. This is where brilliance lives.
Celestyn Jewels is a partnership built on a simple thesis: the diamond supply chain has too many hands, and every hand takes a margin. We removed them.
Our Surat partner sources directly from the world's largest CVD lab-grown diamond growers. No brokers. No distributors. No legacy markup.
