What are the 4C’s?
The 4C’s is a terminology created by the Gemological Institute of America (GIA), used to describe four main attributes of a diamond’s quality; Colour, Clarity, Cut and Carat Weight.
Are Shirin Uma diamonds certified?
Our diamonds are certified by the most reputable laboratories in the world, the majority of which have been certified by GIA (Gemological Institute of America).
Is it safe to receive a diamond in the mail?
Goods purchased online are sent by FedEx or Royal Mail Special Delivery and are insured. If there is a high value item, it would be sent fully insured using a shipping company that specialise in high value and luxury items only.
What gemstones does Shirin Uma use in its jewellery?
In our current collections, we use precious stones; diamonds, emeralds, blue sapphires and rubies.
If we have been commissioned to create a bespoke piece and the client has requested semi-precious stones or pearls for example, we are more than happy to oblige.
Can I have my damaged/worn gemstone made to look new again?
The stone would need to be viewed physically and assessed before we could confirm, but we frequently recut and polish diamonds and other precious stones, giving them a new lease of life.
If I am having my goods shipped, do I pay customs duty & tax?
Shipping is complimentary but you will have to pay customs duty and tax.
How long will it take for my order to arrive?
From the time of shipment, we would advise 7-10 business days, although our clients usually receive their jewellery earlier than this.
How long will a bespoke design take to create?
This would depend on how intricate/complex a design is. Usually, once the design concept has been completed and approved, we allow four weeks as standard practice.
Whether the design is simple or complex, we will always advise you before taking a deposit on the length of time it will take to create.
Of course, under some urgent circumstances, we have been known to make miracles happen, so please do let us know if you have a specific timeframe and we will always do our best to accommodate your request.
What are the shipping fees?
Shipping is complimentary.
How do I make payment?
You will be invoiced, payable via bank transfer.
I would like to have my jewellery engraved, is this a service you offer?
We offer both hand engraving and laser engraving and each request is assessed individually. Please contact us for more information.
