Visit Marcus TempusGemstone Questions
Useful to know.
Can I view gemstone jewellery in the showroom?
Yes. Selected jewellery is held in our Barnet showroom. Contact us before travelling if there is a particular piece you would like to see.
Can you source a particular gemstone?
Yes. We can discuss sourcing a particular gemstone variety, colour, cut or size through our jewellery and gemstone suppliers.
Is natural zircon the same as cubic zirconia?
No. Zircon is a natural gemstone. Cubic zirconia is laboratory-made and is a completely different material.
Can a One & Only piece be repeated?
Sometimes the setting can be recreated, but the exact gemstone may not be repeatable. Natural colour, pattern and inclusions vary from stone to stone.
Not all treasures are diamonds.
