Ask a question

I stepped out of my comfort zone to buy this beauty, the largest solitaire diamond I have ever owned.

I was drawn to its liveliness and clarity. The colour is N, but the warmth does keep the price very reasonable.

It’s an old brilliant cut weighing 2.66 carats in a platinum pierced mount that was handcrafted in about 1940.

Two small diamonds on each shoulder add the finishing touch to the minimalist design.

The stone has been certificated by our leading diamond grader in Sydney, and comes with a diamond grading report and an independent valuation.
