How do I order a TGF Engagement Ring?
We recommend booking a free initial phone consultation with our in-house diamond specialist, Ren, to gain an understanding of how we will create the perfect engagement ring for you. At this stage it would be good to know your budget and date you have in mind to propose.
Please call Ren on (+44) 020 7439 9357, Monday – Friday, 9am-5pm.
If you would like to proceed, we will source a selection of diamonds for you to chose from. Ideally, you will make an appointment to meet with Ren at our London store to see the stones for yourself. However if it is not possible to visit us in-store we will send high resolution photos with an honest description of each stone.
Please allow up to a week to source your perfect stone for you.
We make each ring to order. The process from confirming your order to creating your unique ring can take up to a month in total, so please take this into consideration if you have a particular date you need it by.
It’s great if you know the ring size you want, but don’t worry if you don’t (and don’t risk spoiling the surprise by ‘subtly’ trying to figure it out – they will notice*), we can make the ring in a standard size that we will happily resize for free after they have said yes. Even better if you can both come back into the store to get professionally measured.
Please note that we are currently only selling the wedding collection via our London store. If you are unable to collect in our London store and need your engagement ring shipped, we can quote for this when you enquire. Due to the high value of diamonds we will have to use a specialist courier to ensure safe delivery of your treasured ring. We can ship internationally.
For any further questions, please email Ren who will be happy to help.
*If your loved one has any inkling you’re about to put a ring on it, stay savvy. To start with, clear your browsing history once you’ve read this and don’t favourite the TGF Wedding landing page in your browser for goodness sake.
The 4 'C's
The 4 C’s refers to the 4 main elements we look for when choosing the best diamonds for you.
Possibly the most important element of the 4 Cs. When a stone is cut to precision it will show the diamond’s magical brilliance and interaction with light (the sparkle) – which is why we love diamonds so much! To compromise on the cut compromises on the overall look of the diamond.
Diamonds are graded from D – Z; D being colourless and the most desirable through to Z which is yellow. The whiteness of the diamond contributes to its brilliance when combined with the other Cs. We will only source diamonds that are graded from D-F; these are defined as ‘colourless’.
Clarity is defined as the absence of inclusions and blemishes. During a diamond’s formation when it is exposed to extreme heat and pressure, it can contain unique birthmarks, either internal (inclusions) or external (blemishes). Diamonds are cut to maximise the clarity, the fewer inclusions there are, the more expensive the diamond becomes.
A carat is the weight of the diamond. A carat doesn’t define the size of the diamond, this is a common misconception. Getting the biggest diamond doesn’t necessarily mean you will get the biggest carat. Choosing the correct carat will ultimately come down to the stone you have you heart set on and you think will look best on your future fiancé’s hand.
Diamond Shape & Weight
Our designs are made to fit round brilliant diamonds. This is the most classic and popular diamond shape. At this time we don’t offer different diamond shapes.
We offer 0.5 carat and 1 carat diamond weights as standard. If you have a bigger budget in mind and are looking for a special diamond with a higher carat, please contact Ren directly and we can source this for you.
Gold & Platinum
We only offer our smaller wedding and engagement bands in 18ct gold or platinum.
We offer our larger wedding bands (5mm, 9mm and Hewn) in 9ct gold as they are weightier rings and the price difference is quite a lot higher. However we would recommend choosing a minimum of 18ct gold for your wedding bands as it has a higher gold content and it looks brighter.
This collection is not available in silver. Silver is too soft to set diamonds; a diamond is much harder than silver so there is a chance the silver could wear away after a time causing the stone to come loose. And besides, if you’re going to spend money on a beautiful diamond, you want it to shine and to look its best.
How to Clean Your TGF Diamond Engagement Ring
A clean diamond not only reflects light better but also looks bigger that one that has been dulled by skin oils, soap and cosmetics.
The simplest way to wash the film that accumulates on diamonds at home is by making a detergent bath (washing up liquid).
- Prepare a small bowl of any mild detergent.
- Brush pieces gently with a toothbrush while they are in the bath.
- Run under warm water.
- Pat dry with a soft lint-free cloth.
Harsher cleaning methods are not recommended for home use; including powered abrasive household cleaners, ultrasonic cleaners and steam cleaners.
We offer a complimentary a check up and annual cleaning service on your TGF diamond rings in our London and Los Angeles stores.
The Mohs Scale of Mineral Hardness
The hardest gem stone of all is made of just one element: carbon. They were made approximately 1-3 billion years ago, and without getting too bogged down with the intricacies, we thought we’d share this description from Live Science of how geologists currently think diamonds were created.
1. Bury carbon dioxide 100 miles into Earth.
2. Heat to about 2,200 degrees Fahrenheit.
3. Squeeze under pressure of 725,000 pounds per square inch.
4. Quickly rush towards Earth’s surface to cool.
5. Mic Drop.
Diamonds are believed to be 58 times harder than anything else in nature and its hardness of 10 on the Mohs hardness scale. The Mohs Scale of mineral hardness originated in 1812 by German mineralogist Friedrich Mohs who chose 10 minerals and assigned numbers to them based on the relative ease or difficulty with which one could scratch another.
Although it’s worth noting it doesn’t give a completely fair representation of the strength of diamonds; for example, corundum is classed as 9 on the Mohs scale, but diamonds are many times harder. Only a diamond can scratch a diamond.
It is also worth noting that diamonds can scratch precious metals, so if your diamond is loose in its setting it could wear through over a period over time.
Although diamonds are hard, they’re not indestructible. Any stone, including a diamond, will break if it’s hit hard enough and in the right place. Please take care of your diamond ring and it should last a lifetime.
We buy our diamonds from a trusted gem stone supplier that we have been using for years. We don’t offer certified diamonds as standard, however, we can happily source certified diamonds of you, but the price will increase significantly. Please ask at the enquire at the time of enquiry so we can compare prices for you.
Why Can't I Purchase Certain Rings via the Website?
We cannot set fixed shipping prices on the website for the diamond engagement bands or heavier bands (5mm, 9mm and Hewn), however if you need your diamond engagement ring posted to you, we can make this happen, but we will need to quote for a specialist courier as price will vary dependant on location and value of your ring.
The thinner bands (Cross My Heart, Astral Light and Ad infinitum) can be purchased online and sent with our usual courier service.
Please email Ren for a quote.
We would prefer it if you could collect your diamond ring in person in-store. If this isn’t possible, we can post domestically and internationally, however due to the high value of the diamonds we are unable to use our current delivery company and will have to use a specialist courier who guarantee the safe arrival of your ring. Please enquire for a quote.
