When buying a diamond, everyone talks about "the 4 Cs". It sounds technical, but it's simple and helps you spend your budget well. Here it is in plain terms, from a workshop that works only with certified natural diamonds.
The 4 Cs
1. Cut — the most important
It's how the diamond is cut, and it's what makes it sparkle. An excellently cut diamond returns light like a mirror; a poorly cut one looks dull even if large. If you must prioritise one C, prioritise cut.
2. Colour
Graded from D (colourless, purest) downward. The more colourless, the cleaner it looks. Tip: in yellow or rose gold you can drop a little colour without it showing, and save.
3. Clarity
The diamond's tiny natural inclusions. Many aren't visible to the naked eye. You don't need maximum clarity — "eye-clean" is enough.
4. Carat
The weight (size). Price rises non-linearly: just under the round weights (0.90 instead of 1.00 ct) usually offers great value.
How to prioritise on a budget
Our usual recipe: excellent cut + eye-clean clarity + colour balanced with the metal + the size your budget allows. That gets you maximum sparkle for your money.
Why certified and natural
An independent certificate guarantees what you're buying. And at Arelana we work exclusively with natural diamonds: finite, irreplaceable and better at holding value — which makes sense for a lifelong piece.
Frequently asked questions
Which C matters most?
Cut. It affects sparkle the most.
Do I need maximum clarity and colour?
No. Eye-clean and a colour balanced with the metal look perfect and save money.
Are all your diamonds natural?
Yes, natural and certified.

Gold & Diamond Jewellery Repair and Restoration in Barcelona
The jewellery we love most is the jewellery we wear most… and sometimes it breaks or wears down. At Arelana we repair and restore gold and diamond jewellery in our Barcelona atelier, with the same care we put into making it: respecting each piece's original detail.
What we repair
Our approach: premium and careful
We work on gold and diamonds — not costume jewellery — with the delicacy a piece of value (sentimental or material) requires. We respect the original design: the idea isn't to "change it" but to bring it back to life as it was.
The process
Repair or transform?
Sometimes a heavily damaged piece — or one you no longer wear — makes more sense to transform into something new than to repair. We advise you honestly on what's best. (See transforming old or inherited jewellery.)
Frequently asked questions
Do you quote before repairing?
Always. We value the piece for free and give a fixed quote before starting.
Can I send my jewellery if I'm not in Barcelona?
Yes. We work with clients across Spain and tell you how to send it safely.
Do you repair any jewellery?
We specialise in gold and diamond jewellery. If it's costume jewellery, we'll tell you honestly.

Keepsake Jewellery: Turn a Loved One’s Pieces into a Tribute
Some jewellery is worth far more than its gold: a mother's, a grandmother's, a person who is no longer here. Keeping it in a drawer is one way to preserve it; turning it into a piece you carry with you is a way to keep them close always. At Arelana we create keepsake jewellery from a loved one's pieces, with all the care they deserve.
What we can do
Stories we've been part of
These are special commissions, and we treat them as such: with time, care and respect.
How we do it
With great care and transparency at every step: prior valuation, a design approved by you before anything is touched, and constant communication. We know what these pieces mean. (See our transform inherited jewellery service.)
Frequently asked questions
I'm afraid of losing the sentimental value. How do you handle it?
With utmost respect: nothing is touched without your design approval, and we guide you every step.
Can you keep part of the original piece?
Yes — if you wish, we can integrate an original element (a stone, a fragment) into the new piece.
Can something be engraved?
Yes — a name, a date or words that make the piece even more personal.

Melt Your Old Gold Jewellery to Create a Unique Piece
Do you have gold sitting in a drawer — broken chains, unworn rings, single earrings — and don't know what to do with it? Instead of selling it by weight, you can turn it into a new piece you'll actually wear. At Arelana we melt your own gold to create a bespoke piece in our Barcelona workshop. (Part of our transforming old or inherited jewellery service.)
How it works
Is all the gold reused?
Almost all. There's a small natural loss in melting and refining, and sometimes it's worth adding a little new gold for the chosen design. We explain everything transparently before starting: how much gold you have, how much is reused, and the final quote.
What you can create
A ring, a bracelet, a pendant, wedding bands… whatever you imagine. The gold from several old pieces can become one special new piece.
Frequently asked questions
Is my gold good enough quality?
We check it for free. We work with various purities and tell you what's possible with yours.
Can I combine gold from several pieces?
Yes, very common: we gather the gold from several pieces to create a new one.
And if there isn't enough for the piece I want?
We add the missing gold at the day's price, fully transparently.

Transform Old or Inherited Jewellery into a New Piece | Barcelona
Almost all of us keep jewellery in a drawer that we no longer wear: a grandmother's ring, dated earrings, a broken chain, wedding bands from another time. They hold enormous value — sentimental and material — but no one enjoys them there. We can turn them into a new piece you'll actually wear, keeping their story alive. We do it by hand in our Barcelona atelier.
The idea: your family's gold, a new piece
It's not about "selling the gold". It's about reusing it: melting that gold, recovering its diamonds or stones, and creating a new piece designed by you. The result literally carries the material of the people you love.
What we can do
Real stories
Each one started in a drawer and became someone's favourite piece.
How it works
Frequently asked questions
Is all the gold reused?
Almost all. There's a small natural loss when melting; we explain it transparently before starting.
Can you reuse the diamonds from an old piece?
Yes — we recover diamonds and stones in good condition and set them in the new design.
It has huge sentimental value and I'm nervous.
We understand completely. We guide you at every step, with a valuation first and the design approved before we touch anything.

Emeralds, Sapphires and Rubies: Natural Gemstone Jewellery | Barcelona
The diamond isn't the only stone that moves us. Natural coloured gemstones — emerald, sapphire, ruby — give a piece character, colour and history. At Arelana we set them to measure in 18K gold, always natural and top quality. Here's their appeal.
Emerald
Intense green, a symbol of hope and renewal. It's a living stone, with its natural internal "garden" that makes it unique. Beautiful in rings and pendants, especially in yellow gold.
Sapphire
Though associated with deep blue, natural sapphire comes in many colours. It's very hard-wearing (ideal for daily use) and conveys serenity and loyalty. A timeless classic.
Ruby
Red par excellence, a symbol of passion and life. A rare, noble stone that brings warmth and presence. Spectacular as a centre stone.
Natural stones, always
As with diamonds, we work only with natural stones: they have soul, rarity and hold their value. Each one is different — and that's precisely their beauty.
Basic care
Coloured stones appreciate gentle handling: avoid knocks and chemicals, and an occasional professional clean (we do it at the atelier) keeps them radiant.
Frequently asked questions
Can they be worn daily?
Sapphire and ruby are very hard-wearing. Emerald is a little more delicate; we advise on the most protective setting.
Can I make an engagement ring with a coloured stone?
Yes, increasingly requested. (See coloured gemstone engagement rings.)
Are they natural stones?
Always natural and top quality.

Custom Jewellery in Barcelona | The Arelana Atelier
Arelana is an artisan jewellery workshop in Barcelona. We're not a chain or a display of repeated pieces: we're an atelier where jewellery is designed with you and finished by hand, in solid 18K gold and with 100% natural, top-quality diamonds.
The craft
Every piece passes through hands, not just machines. We design, cut, set and polish with time-honoured technique and today's tools (including 3D design, so you see the piece before it's made). That care is what makes a piece last — and be enjoyed — for a lifetime.
What we do
How we work
Online and in person
You can visit the workshop or do it entirely remotely: we advise you, show you renders and ship the piece to your door. We serve Barcelona, Vilanova i la Geltrú and all of Spain.
Frequently asked questions
Can I order a piece without visiting the workshop?
Yes. Many clients do it 100% online, with video-call advice and free shipping.
What materials do you use?
Solid 18K gold and 100% natural, certified diamonds and stones.
Do you offer a no-obligation quote?
Always. Tell us your idea and we'll prepare a proposal with no commitment.

Matching Your Wedding Ring with the Engagement Ring
The engagement ring and the wedding band are worn together, on the same finger, for life. Making them sit well together — or even interlock like a puzzle — makes the whole look perfect. At Arelana we design wedding bands to match your engagement ring, custom-made in 18K gold.
Ways to combine them
Designing them together (the best option)
If you don't have the bands yet, the ideal is to plan them alongside the engagement ring: we make sure they fit perfectly and the set makes sense. And if you already have the engagement ring, we design the band around it.
And his ring?
We also make the matching men's band (same gold, coordinated finish), so the couple's set works together.
Frequently asked questions
I already have the engagement ring — can you match the band?
Yes. We design the band from your existing ring so they fit.
What's a "fitted" band?
A band designed to hug the solitaire with no gap; the set looks like one piece.
Can you make both (hers and his) coordinated?
Yes, we design them as a couple's set.
