CARE ADVICE

What are our gemstones quality guidelines?

Fenton & Co. only source fine, natural gemstones, that are expertly cut to bring out the best colour and brilliance of each gemstone. We select gemstones that are visually compared against masterstones that we have chosen, to ensure that the colour of these natural products are as closely matching to the depicted gemstone colours on our website as possible. We mainly source gemstones, that are evenly saturated and that are transparent, or translucent and cut it (using reasonable care and skill) to give them brilliance. All gemstones will have some inclusions that in some cases may be visible to the naked eye. We generally avoid gemstones with black inclusions and with surface reaching fissuers.

Discrepancies between gemstones

Gemstones are a product of nature and as such are an individual and unique product of geological creation. Some gemstone varieties, such as rubies and sapphires, are not exclusively found in one location, but are available in several different deposits around the globe. Each deposit has its own specific geological formation and characteristics and in each of these deposits the composition and concentration of the "colouring elements" is slightly different from the next. Even rubies from the same source deposit (mine) can have a different colour, or hue and it is therefore understandable that colour-matched colour gemstones command a higher price, as a larger quantity of gemstones has to get produced and assorted to create a perfectly matched set (such as those we use for our Fenton & Co. Garland Rings).

Gemstone colours vs. renderings

When we are sourcing the gemstones that we use in our Fenton & Co. engagement rings, we travel with a set of masterstones, which we have selected to represent our Fenton & Co. level of quality. These masterstones serve as limit samples to benchmark each new gemstone purchased against the established standard. While we allow a small variation of colour intensity and saturation (since we are dealing with a natural product), we are making sure, that our colour selection is aligned to the gemstone colour, which is shown on our website, as much as possible. However, it must be noted here that "colour is virtually in the eye of the beholder", meaning that each human being has a unique set and quantity of colour receptors in his/her eye and colour perception is therefore subjective. The perception of colour is furthermore affected by the presence and quality of light. For instance, different digital devices feature different monitor and screen technology to display colour and a bright back-lit desktop screen will show the same picture in a different colour than a small LCD screen on a mobile phone. It should therefore be understood, that the colour gemstone that you have received from Fenton & Co. might look slightly different in colour than that of the picture you have seen online.

Gemstone size guidelines

We select each of our gemstones based on a large number of contributing factors, of which size is one. Gemstones of this size and quality are often not cut in exact calibrated sizes (8x6, 9x7mm etc) so there might be some slight variances in the mm size of your gemstone. All gemstones will be closest to the stated size with a tolerance of up to 0.45mm. We are always happy to provide exact information upon request.

Gemstone treatment overview

Fenton & Company is only working with natural colour gemstones, that are treated in a way that follows common jewellery and gemstone industry standards. The AGTA gemstones guidelines represent an international value system and provide the applicable nomenclature. Fenton & Co. colour gemstones, might be heat treated (to improve the colour intensity of a gemstones and our emeralds might be clarity enhanced by having been treated with a colourless oil. However, we don't believe in any other known gemstone treatment, such as laser drilling, fracture filling, deep diffusion treatment, berylium treatment and glass-filling are treatments and therefore do not use in relation to our carefully sourced engagement rings.

Emerald and aquamarine specific warnings and care

Heat can damage emeralds, especially by extending existing fractures or fissures. Any expose to heat above 60 degrees Celsius risks making the oil in the emerald change viscosity and "run". A trip to the sauna can permanently damage an emerald, and so can steam coming out of a cappuccino machine for instance. Emeralds should also not be exposed to dish washing water (particularly if it involves oil removing dish soap). Light (as it creates heat) and chemicals can cause the oil, that is used to fill fissures, to change the appearance of an emerald. The complete removal of clear oil can result in the deterioration of clarity of an emerald.

Finally, do not subject your gemstones to drastic or sudden temperature changes. For instance, when wearing your Fenton & Co ring, do not reach into an ice box, and then suddenly hold your hand near a boiling pot of water.

Emerald and aquamarine cleaning

Since the great majority of cut and polished natural emeralds contain filled fractures, it’s risky to clean them in ultrasonic bathes, or with steam. Ultrasonic vibrations can weaken already fractured stones, and hot steam can cause the oil to seep out of fissures. Using warm water coupled with gentle scrubbing with a soft brush is the safest way to clean emeralds.

Metal purity and diamond quality overview

All Fenton & Co. engagement rings are manufactured in 18 karat gold, or in 950 platinum. The purity of our rings are guaranteed by the hallmark of the British Government, that checks and verifies the metal purity of each and every Fenton & Co. engagement ring. Our proposal rings are manufactured in 925 Sterling silver and are likewise audited and hallmarked through the British Hallmarking Authorities. Unless specifically stated otherwise, our expertly cut diamonds are of G-H color grade and of VS clarity. The diamond weights stated on our website are minimum weights (there are no negative weight tolerances).

Correct ring care and servicing

With a little bit of regular care, your Fenton & Co. engagement ring will remain sparkly for years to come. Between professional servicing, most gold and platinum jewellery can be maintained with a non-abrasive cleaner, or just a bit of lukewarm soapy water. Examine your engagement ring settings regularly to make sure the prongs are snug fitting and the gemstone(s) are secure. If you have any doubts about a gemstone having come loose, don't try any repairs with glue or other DIY, but take the ring to a professional gemstone jeweler to tighten the setting, if required. Avoid exposing gold jewellery to household bleach and aggressive cleaners, which will cause gold to discolour and possibly damage the gold alloy by reacting with the copper. Jewellery storage is important as well. You should remove your jewellery when you sleep and between wearings, we recommend that you place it back in its original case or another suitably lined box or pouch. Avoid storage in a joined box where diamonds and hard gemstones can scratch and damage your polished gold and platinum surfaces by abrasion and touch.

Gemstone Care

Although gemstones are some of the hardest natural materials in the world, exposure to impact can make them vulnerable. In some cases the gemstone shape (for instance a baguette cut) can contributes to the vulnerability of a gemstone. Larger stones in particular should be worn and stored with care and protected from hits and abrasions.

Porous gemstones, such as emerald may be enhanced by oils, so it’s particularly important to avoid contact with face and body creams, sun tan lotion and household chemicals. Wash porous gemstones in lukewarm water with no soap additives (that could dissolve the oil) and dry with a lint-free soft cloth. Porous gemstones (such as emeralds) are more susceptible to damage when being exposed to heat. It is therefore recommended to avoid wearing jewellery to the beach or in the sauna, where the sea salt, sun and sand could easily harm the appearance of your gems. Likewise, porous gemstones should not be worn in a swimming pool or Jacuzzi where chlorine or other chemicals in the water can attack the gemstone substance.

Gemstone Country of Origin

We have stringent processes to ensure that we only source gemstones from the approved countries of origin described on our website and rely on both our direct relationships with dealers as well as third party lab testing to uphold these standards. We strive to ensure that we are always communicating the correct information to you in this respect. If there is an eventuality in which we unknowingly sell you a gemstone that is not from one of these countries and you are able to demonstrate that to us, we will exchange that for a stone that we can reliably prove the origin of immediately.

General wear and care advice

Colour gemstones have different hardness properties that are measured in Mohs (relative Moh's hardness scale). While diamond, ruby and sapphire are relatively hard and hard wearing gemstones, there are softer gemstones such as emeralds and aquamarine, that require protection and care, to avoid permanent stone damage. It is a general good practice to remove rings when cleaning, where the jewellery might get in contact with acids, cleaners or other chemical agents that could either damage the gemstone or the gold alloy. Once you have removed your Fenton & Co. engagement ring, wipe it with a soft cloth so that any residue from air pollution or contact dirt gets removed. Store the ring in a jewellery box, where the ring is not touching any other jewellery piece - to avoid scratches on the polished gold surfaces.

Insuring your investment

Once you have purchased your Fenton & Co. engagement ring, we recommend you ensure it so that it is properly insured, in the event of theft or loss. Although homeowner's and renter's policies will in most cases cover a portion of your loss, it is often a small amount in comparison to the original cost of an engagement ring or wedding band. It is advisable to find out how much is covered by the policies you have in place, and then decide on securing additional policies for adequate coverage.

Most insurance companies will not insure fine jewellery without an appraisal, so make sure you find out which appraisal reports are acceptable to your insurance company. Make sure you read the details of the policy carefully before you pay for extra insurance. Be conscious that your insurance company may require updated jewellery appraisals on an annual basis and be prepared to have your jewellery appraised at least every few years and proactively submit the updated appraisals.

Lead time to manufacture and deliver

We at Fenton & Co. believe in building lasting relationships with our customers and we will go out of our way to find just the right colour gemstone for the ring that you have selected. Many times we might be able to offer you a few gemstone options, where you can decide between similar gemstones with regards to size, colour saturation or carat weight. Our regular order lead time for completing your ring of choice, specific to your size and preferences, is 4 weeks. However, we might be able to expedite your order, if we are quickly able to procure your gemstone, so please let us know what your preferred delivery date is and we will try to meet that date. On some rare occasions, we might require up to 6 weeks lead time, particularly when gemstones of higher carat weight or of specific colour have been selected.

Resizing

As part of your purchase we are happy to offer one round of free resizing. If your ring needs to be resized above two sizes either way, we recommend that you exchange your ring for a larger size, rather than resizing to protect the long-term structural integrity of your ring. Please note that we cannot accept pieces that have been worn or resized, either by us or another jeweller for exchange or return.

Breakages due to poor care

Fenton & Co. will not be liable in relation to breakages which are caused by impact that the wearer subjects a gemstone to, and not by any manufacturing flaw. As mentioned above, some gems are softer and more prone to breakage than others,. Even the hardest substance on earth (diamond) breaks if hit with the right amount of force at the right angle. This fact is even used when cutting diamonds, as the diamonds are "knocked" along the planes and thus get broken off in a controlled way. It is therefore critical that you research which gemstones are most suitable for the lifestyle of the wearer. For instance, since emerald is one of the most fragile and breakable stones, we would not recommend it to a wearer who would wear it whilst doing a lot of physical activity or who handles chemical substances whilst wearing the ring. Loss of pave band or side stones is classed under regular wear and tear, the prongs holding these should be checked regularly as part of ring care and servicing.

Shipping and Resizing Policy

We offer free, insured shipping and free, insured returns within 60 days. All of our orders are made to order and delivered in 4-6 weeks with an average of 3 weeks. As well as free shipping, we also offer one free resizing per purchase.
