Whether you love this ring for its twist on the classic gypsy ring, or you enjoy the romantic 'toi et moi' (French for 'you and me') interpretation of the two central old mine cut stones, this is a gorgeous piece! The stones (two old mine cut diamonds and two single cut diamond accents) range from SI1-SI2 clarity, F-G colour and are in lovely little starry flush settings. The diamonds are sparkly and lively, and the band has a fantastic weight to it - this is a well made piece that feels as good as it looks!

Before you buy
How do you authenticate your pieces?
We carefully assess every piece using our gemmological training, specialist tools, and industry experience. We are both GIA Graduate Gemmologists and have also completed the Applied Jewelry Professional (AJP) qualification.
We work closely with our jeweller, who has almost 50 years of experience and is also a qualified gemmologist.
Carat weights are estimates based on measurements taken in the setting unless otherwise stated. Precise weights can only be obtained from loose stones. Many of our diamonds are old cuts, which are often asymmetrical and not calibrated due to traditional hand-cutting techniques.
We aim to provide clear photos and videos from multiple angles to help you purchase with confidence.
Do US customers have to pay tariffs or duties?
No - for United States customers, the price shown includes insured DHL Express or Australia Post shipping and import duties/tariffs.
This means there should be no separate bill for these charges on delivery. We always ship at full declared value so your parcel stays compliant, secure, and fully insured.
Do you offer layaway or payment plans?
We offer an interest-free layaway (lay-by) service on orders over $500 AUD - please get in touch using the form below to set this up. Full details can be found on our layaway policy page.
