You may remember the stunning Tanzanite & Diamond Cluster Ring featured in the Supper Club Auction Booklet.
The piece was withdrawn from auction at the event.
Please note this ring is not brand new, it is a vintage piece created by jeweller Julia Jefferson; it has now undergone professional reconditioning thanks to Cambridge Jewellers, and it has come up spectacularly!
We’re now offering a closed tender opportunity exclusively to our Rotorua Supper Club guests and supporters.
This breathtaking ring is cast and hand assembled in 18ct yellow gold, featuring a vivid oval Tanzanite from Tanzania, surrounded by 22 brilliant-cut diamonds in an elegant cluster setting. It’s a striking statement piece, generously donated by Julia Jefferson, an incredible supporter and volunteer for Ronald McDonald House Charities. New 2026 valuation by Wellington Jewellery Valuations values it at $12.5K.
We have already received an opening offer of $10,000.
We now invite confidential offers above this amount until SUNDAY 26TH APRIL 2026.
To submit an offer, simply email us at [email protected]. The highest offer at closing will secure the ring.
The ring is available to view in person, please call Win Macmillan on 027 4763010 to arrange a time.
This is a rare second opportunity to secure a truly exceptional piece while supporting the families that use the RMHC and the Rotorua Family Retreat!
