Origin
Ceylon's bright cornflower and royal blues against Australia's deeper teals and partis, compared on colour, price and treatment.
Colour
Royal and cornflower blue, teal and parti, pink, yellow and green, and what makes one colour more valuable.
Treatment
Why gentle heating is accepted and permanent but must always be disclosed, and why fine unheated stones are rarer.
Price
Real per-carat prices in AUD from our own stock, and what colour, size and heat add.
All our gemstones are 100% natural, and we only sell and source earth-mined natural gemstones and diamonds. Each ring is made to order in your choice of 9K to 21K gold, with bespoke commissions handcrafted in our Pitt Street workshop in Sydney, and an independent valuation certificate is available with any purchase for insurance purposes. Prefer to start from the stone? Design your ring around any loose sapphire in the house, or book a consultation at our Sydney showroom or by video.
Royal blue is the deepest saturated blue and the most sought after; cornflower is lighter and brighter; Australian blues run darker and often carry a hint of green. We show the options side by side at consultation, in daylight.
Some are and some are not. Heat treatment is a traditional enhancement of a natural stone, and unheated stones are rarer and priced accordingly. Heat treatment is a traditional enhancement of a natural stone; unheated stones are identified as such and priced accordingly.
From Ceylon (Sri Lanka) and from Australian fields, every one 100% natural and earth-mined.
