Rarity, quality & value

While coloured stones of gem qualities are rare, untreated and unheated sapphires, spinal and rubies of good quality are incredibly rare and make up less than 1% of what is available on the gemstones global market.

We believe that these gemstones have considerably more charm and have their value on the rise compared to treated gemstones.

At Serendi, we believe that these top-quality gemstones have considerably more charm and store more value than heated gemstones, and therefore have their value on the rise compared to treated gemstones, gemstones of lower qualities and diamonds. Our spectacular spectrum of coloured gemstones grants you a unique opportunity to pick your fairy-tale gemstone and create an exclusive jewel.

We exclusively offer the finest quality gemstones amongst the unheated and untreated gemstones. Each of our gemstones come with a third-party certificate of authenticity and quality provided by world-class laboratories like The Gem Research Swisslab (GRS) of Switzerland, to provide an extra layer of certainty and assurance.

To support hard-working individuals and their families, and to make sure we purchase and offer the finest quality gemstones at the most competitive prices, our procurement team directly sources gemstones from small-scale miners and the small circles around them, mainly in Sri Lanka where our procurement team is based.

Coloured gemstones are simply amongst the most beautiful marvels of nature. Every one of us in their life goes through special events that would be remembered and celebrated forever. At Serendi, we aspire to provide you with what would undoubtedly be the quintessential seal of your special life moments: our precious gemstones.

When choosing a precious gemstone for those special events, you will never find better than natural and untreated precious gemstones of colour. Each gemstone has evolved in nature over millions, if not billions, of years following a unique path that makes each one of them visibly different from the others and as unique and special as the event you are about to celebrate.

When considering coloured gemstones, particularly sapphires and rubies, understanding the terms “natural” and “untreated” are crucial to making an educated decision.

A natural untreated sapphire or ruby is one that has been taken from the ground and then faceted. Nothing at all was done to the stone to alter the natural beauty, which only elements and processes in the earth created naturally. These sapphires and rubies are exceptionally rarer and more valuable than heated ones.

The word “natural” identifies a gemstone that has been developed in nature, not synthetically created in a lab. The word “untreated” means that a sapphire or a ruby has not undergone any heat or chemical treatments to improve its colour or clarity.

Natural and unheated gemstones, whose value appreciates with time, are superior to diamonds, whose value is in decline over the last decade.

Precious gemstones and jewellery made of natural and unheated gemstones constantly appear in most high-end publications like Vogue and are in trend amongst the finest jewellery houses and distinguished families and individuals all over the world.

All of our gemstones weigh one carat and above whether offered in “Jewellery”, “High Jewellery” or “Create Ring” sections are certified and come with a unique original GRS (Gem Research Swisslab of Switzerland) certificate or another world-class company report, also known as a gemstone certificate. These reports have been created by experts at highly-respected GRS laboratories or other world- class companies around the world. They contain a detailed description of the characteristics of the specific gemstone.

Serendi proudly offer the four top metal options of white gold (18k), platinum, rose gold (18k) and yellow gold(18k) for you to choose from. Each of the four options has its own unique characteristics to satisfy your taste and provide the ultimate setting for your gemstone.

White gold:

White gold is an alloy of gold and nickel, sliver, or palladium. The inclusion of white metals in the alloy gives white gold its silvery colour. White gold is rhodium plated to provide it with a sparkling white appearance. Our 18k white gold is very durable.

Platinum:

Platinum is the hardest metal available. It is pale greyish-white in colour and it does not change colour over time. It is usually the most expensive metal used for jewellery as it is heavier than gold.

Rose Gold:

Rose gold (18k) is also known as pink gold. Serendi use it in special designs where a pinkish metal colour best suits the gemstone(s), and offer it as an option for all rings under "Create". The rose colour is derived from the addition of different alloys to the gold during the casting process.

Yellow Gold:

Our 18k yellow gold has a beautiful rich yellow colour. We offer it for those who like the ever-beautiful original colour of gold.

We ship entirely free within the UK. We ship with FedEx for shipments below £35,000 and with another company for shipments above this amount.

For the pre-made items picked from the “Jewellery” and “High Jewellery” sections, we aim to ship your order within ten working days unless a resizing is needed.

For items created from the “Create Ring” section, and given that all of our jewellery are 100% handcrafted, the handcrafting time for creating a ring cannot be reduced, and therefore we are unable to offer an express service.

Serendi natural unheated sapphires and rubies are particularly hard and durable; in fact, they are as hard as 9 out of 10 on Mohs scale. Therefore, they are not disposed to chipping, cracking or breaking under normal use.

We also only use genuine, high-quality diamonds and gold (18k) or platinum for our jewels.

Gold, for example, is very soft in comparison with sapphires and could easily be chipped by them. The hardness of 18k gold of Mohs scale is about 2.75.

Serendi will bring you fine jewellery in an excellent shiny condition. To keep it like this, and to extend its life, we recommend you do the following:

• Store your jewellery in its original Serendi box when you are not wearing it. This will protect the metal from scratches. Also bear in mind that different gemstones have different hardness and can easily scratch or knock each other if stored together.
• Travel with a jewellery case. While regular storage is essential, travel storage is even more important. Putting your jewellery in a plastic bag or suitcase can cause irreversible damage.
• Gently clean your Serendi jewellery using a soft cotton cloth to remove any oils, dust or contamination. You may also gently use simple, non-abrasive materials like soap and water, with a soft toothbrush.
• Avoid wearing it when you are doing gardening, using a spa or participating in a sport as direct physical pressure or severe temperature change could damage your jewellery.
• If your ring needs resizing or maintenance or you feel it needs professional cleaning, contact Serendi, and we will do this for you.
• For your peace of mind, insure your fine Serendi jewellery items.
• Frequently check your jewellery to make sure the stones are not loose
