Pure gold which is known as 24-carat gold is very soft and not ideal for modern everyday day jewellery. Pure gold is generally alloyed with other metals to enhance its hardness, strength and durability. In this alloying process, the proportion of gold to alloys is defined by the carat number which measures the parts of gold out of a total of 24 parts. In the UK, 18 and 9 Carat gold are more commonly used to craft jewellery, still, 22 and 14 Carat choices are available.

Platinum is an extremely rare metal. It is dense, ductile, naturally hypoallergenic, metal with a glossy white lustred shine. Platinum has a notable history, known to be found in ornamental treasures in ancient Egypt more than 3,000 years ago. The South American Inca Indians also used platinum to adorn their artefacts. The word platinum was derived from the Spanish term platina, meaning “little silver”. As a controversy, the Spanish people considered platinum to be far inferior to silver and its value was dropped during the 15-16th century. During the 1800’s its qualities are acknowledged and crowned back to precious metal.
Favoured by its remarkable strength, longevity, and beauty; today, platinum is regarded as the prestigious choice to mount fine diamonds and valuable gemstones, especially in engagement and wedding rings. Platinum is a very dense metal and feels noticeably heavier than other precious metals. Platinum is also a very malleable metal to craft your jewellery and one of the most resistant metals available and will not be affected by salt water or chemicals. Due to its purity, exceptional resistance and hard-wearing nature, platinum become a practical and glamorous choice for everyday fine jewellery, especially diamond-mounted pieces. Platinum Designs are a luxurious choice as a family heirloom to pass it down through generations.
Platinum is available in 950 or 500 purities. At Autumn and May, we only offer the most superior Platinum 950 fineness.
- Platinum Jewellery has 95% pure Platinum and 5% of alloys like Ruthenium (platinum family) and a trace of Cobalt.

- Platinum is very dense, around 88% heavier than 9 Carat gold, 34% heavier than 18 Carat Gold and four times stronger than gold.
- Only a few hundred tonnes of platinum are produced yearly around the Globe and it is the most expensive of all precious metals in Jewellery.
- Platinum has remarkable resistance to corrosion, and hypoallergenic properties and is considered a noble metal.
- Platinum has a clean grey/blueish white colour
- Platinum requires very little maintenance as it does not tarnish or discolour and is far less malleable than Gold.
- Do not require rhodium plating.

Palladium is an incredibly strong, rare, ductile, naturally hypoallergenic platinum family metal, thus shares a lot of chemical properties with platinum. Palladium was discovered in 1803 by the British chemist and physicist William Hyde Wollaston, who later discovered Rhodium as well. Palladium is named after one of the largest asteroids “Pallas”, which was discovered a year earlier. Palladium has a lustrous silvery-white sheen and has been used as a precious metal by Jewellery Designers since 1939. Palladium gained even more popularity in jewellery when platinum was declared a strategic metal During World War II. Palladium price has fluctuated over the years and sometimes was more expensive than platinum. The British Assay Office started Hallmarking Palladium in July 2009, this reflected immense popularity and dramatic demand for Palladium Engagement and Wedding Rings.
Today palladium become more fashionable and gaining enormous admiration. Palladium is revered as an elegant sophisticated precious metal and is even more beautiful, when mounted with diamonds or precious gemstones, its natural white hue is a great backdrop for diamond setting.

Silver is one of the oldest standing precious metals mined by pre-historic man to create objects, ornaments and jewellery. Silver has a lovely milky white lustrous hue, which sparks to the nickname “metal of the moon.” The word “silver” derived from the ancient Greek word “argyro”, “άργυρο”. Silver is known to be more precious and was more expensive than gold in Egypt during the fifteenth century BC. When “Sterling” was broadly recognised as a standard of English currency, the term, “sterling” now refers to the highest purity of silver and became part of its common name – “Sterling Silver”. Silver is mined all around the world, although Peru is known to have the highest amount of silver available. Sterling silver is a relatively inexpensive precious metal and become a primary choice by contemporary designers.
925 Sterling Silver
- Sterling Silver has 92.5% pure Silver and 7.5% other copper-based alloys.
- Or 925 pure silver parts per 1000 parts, hence the Hallmarking stamp 925 found in Silver Jewellery.
- The copper alloy enhances its hardness, strength and durability but causes the silver to tarnish over time.
- The 925 standard determines whether the jewellery should be designated as “Sterling Silver” or pure silver, anything less than 92.5% do not qualify as sterling silver.
- Sterling Silver is the least expensive precious metal.
- Silver can be transformed into different purities, although most silver designs are exclusively made of sterling silver.
- Fine silver has 999 parts of pure silver per 1000 parts. The fine silver does not tarnish but is extremely soft to use in jewellery. Fine silver is mostly used as investment bullion or trade metal products.
- Some Britannia silver has 958 parts of pure silver per 1000 parts.
Oxidised silver jewellery is essentially darkened, Sterling Silver. The surface has been carefully darkened through a chemical process called oxidisation. Unsurprisingly the surface patina colour occurs when the silver jewellery is introduced to sulphides and creates a layer of silver sulphide on the surface by giving it a blackened look. Oxidised blacken finish is a surface highlight and just occurs on the top layer of the jewellery. Over time, depending on the usage and wear-and-tear the oxidisation may wear off and the silver will shine through. Oxidised silver jewellery should be cared for separately and should not be cleaned with jewellery cleaning dips or harsh chemicals or aggressive polishing which may shred off the blackened detailing.
When required cleaning, only use a mild detergent and a very soft toothbrush with as little rubbing. Oxidisation can be done any time at Autumn and May, simply contact us or ask a member of staff.
. Strong . Ultra-light . Hypoallergenic .
Titanium is an incredibly strong yet amazingly lightweight, naturally hypoallergenic, metal with gorgeous grey colour. Titanium was discovered in 1791 by the British mineralogist William Gregor and named after the Titans of Greek mythology. Titanium is resistant to corrosion in seawater, chlorine or many other household chemicals, making it perfect for those with allergies sensitivities and to be worn in demanding environments. Titanium has the highest strength-to-density ratio of any metallic element and this ultra-lightweight nature is one of the most unique characteristics. Titanium jewellery is more resilient to bending and scratching or it won’t lose its shape in comparison with pieces made from other precious metals.
Jewellery Designers recognised its remarkable qualities and introduced it to their work in the 1990s. At Autumn and May, we only favour pure grades of titanium to craft our Designs. Experience taught us that the 99.2% pure grades of titanium have the best properties to create jewellery. Titanium is particularly brilliant for everyday jewellery like Wedding Rings, or for hypoallergenic earrings and body jewellery. Its masculine grey tinted colour makes exceptional popularity in men’s ranges of Jewellery, such as plain Band Rings, Cufflinks, bold Chains, Men’s Cuff-Bangles and Bracelets.
We understand titanium’s most amazing feature is to take on a whole spectrum of colours. The naturally occurring colourless oxide layer on titanium can be altered by a process known as anodic oxidation. Anodising allows us to control, vary and adjust the thickness of the surface oxide layer, which in turn causes optical interference colours to become visible. The principle is the same as the colours seen in nature and those in a soap bubble or oil on water. By precisely controlling the surface oxide level a spectrum of colours can be achieved. During the process, a specific anodising electric voltage is applied to the part to determine and obtain the desired colour. Titanium anodising is not a coating nor a dyed colour. This oxide layer of colour is reasonably robust and will not fade but is liable to become damaged caused by abrasion.
Titanium Ring Resizing
Most Jewellers will tell you that Titanium Rings cannot be re-sized due to its properties and extreme strength. Our workshop uses updated allows and modern techniques with traditional hands-on approach to create unique titanium pieces. We are able to offer you the peace of mind of a re-sizing service on all Titanium Rings bought from Autumn and May.
Facts about Titanium
- Titanium is 99.2% pure.

Titanium is not Hallmarked as it is not a precious metal.
. Gloss . Elegant . Shielding .
Rhodium is a rare, strong, corrosion-resistant, naturally hypoallergenic noble metal with a silvery white glossy shine that belongs to the platinum family. Rhodium was discovered in 1803 by the British Chemist and physicist William Hyde Wollaston soon after his discovery of the fashionable precious metal – Palladium. Rhodium plating is an electro-plating process and adapted to the jewellery industry in the early 1930s due to its portraying characteristics, quality, and elegance, and its plating help to protect the white gold. Rhodium does not affect by water or heat up to 600 degrees.
As a modern-day jewellery standard, almost all white gold designs are enhanced with rhodium plating to give a brilliant white glossy lustre. Jewellery Designers also introduced rhodium plating to their silver jewellery in order to enhance its appearance with a white glossy sheen and to prevent the jewellery from tarnishing. Although being strong, subject to usage and care, rhodium wears away over time and may reveal the pale white or yellowy coloured white gold underneath. This is less of an issue for occasional jewellery or earrings that do not come in contact with other items. Restoring rhodium plating is a simple process, this will reinstate the shiny gloss appearance and bring back the original brand-new look to your jewellery. This can be done any time in Autumn and May, simply contact us or ask a member of staff. You can also request your white gold rings without rhodium plating, by adding a note during the checkout while placing your order.
