Your Curiosity. Our Transparency
In a world where luxury is often shrouded in mystery, we at Alter Luxe choose transparency.
We receive many questions every day, a sign that those who choose our jewels do so with attention, awareness and a desire to understand what makes each creation special. This is where this section comes from.
We’ve collected answers to frequently asked questions to guide you through every step of the Alter Luxe experience, from first look to final delivery.
Because true luxury is knowing the essence of what you choose.

Do you have the perfect piece of jewelry in mind?
Do you want to transform an idea, a photo or a wish into a jewel all your own? We can make it happen.
We use only the highest quality laboratory moissanite in our jewelry.
This extraordinary gem is composed of silicon carbide (SiC) : a perfect combination of silicon and carbon , which gives rise to an exceptionally strong and brilliant crystalline structure.
Visually indistinguishable from diamond, moissanite offers even more intense brilliance thanks to a higher refractive index (2.65–2.69) , which gives it vivid reflections and an unmistakable sparkle.
With a hardness of 9.25 out of 10 on the Mohs scale , it is second only to diamond in terms of resistance: perfect for a jewel to be worn every day, without fear of scratches or signs of aging.
Furthermore, it is ethical, sustainable and traceable : a conscious choice that combines luxury and values.
Each stone is selected for color grade (D–F) and clarity (VVS) , and is accompanied by an Alter Luxe certificate attesting to its characteristics.
Moissanite is a 100% real stone , with its own chemical composition and crystalline structure.
It is not glass, it is not zirconia and it is not a “fake crystal or diamond” like those used in jewelry: it is a precious gem created in a laboratory, with authentic, measurable and certified physical characteristics .
It is made of silicon carbide (SiC) , a naturally extremely rare material, first discovered in 1893 by Henri Moissan , inside a meteorite crater in Arizona .
In nature it is rarer than diamond itself , and it is precisely its extraterrestrial origin that makes it unique.
Today it is grown in the laboratory to ensure quality, traceability and sustainability , without aesthetic compromises.
To the naked eye, it is almost indistinguishable from a diamond , but it has an even greater brilliance , thanks to its higher refractive index (2.65 versus 2.42).
It is also extremely durable, with a hardness of 9.25 out of 10 on the Mohs scale : perfect for everyday wear, without fear of scratches or tarnishing.
Choosing a moissanite means choosing a real, ethical, luminous and unusual stone.
A gem that doesn't pretend to be a diamond , but shines with a story all its own .
To the naked eye, absolutely not .
Moissanite is visually almost indistinguishable from a diamond , even to the most expert eyes. It sparkles intensely, has an extraordinary transparency and a light that often leaves those who look at it speechless.
In fact, many jewelers and gemologists use professional tools to distinguish it, because it is not possible to do so just by looking at it .
And indeed, those who receive a moissanite ring often receive more light, more ethics and more emotional value , because they know that it is not only a symbol of love, but also of awareness.
Moissanite also has a romantic and unique origin : it was born from a shooting star - discovered in a meteorite in 1893 - and carries with it a special story, perfect for those who want to give something real and different, without compromise.
It is not a copy. It is a choice. A gem that does not pretend to be a diamond, but that knows how to shine with its own light.
Yes, moissanite is increasingly chosen by international celebrities, influencers and designers , not only for its extraordinary appearance, but for the values it represents : sustainability, transparency, awareness.
One of the most notable advocates of ethical jewelry is Meghan Markle , who has worn brands known for using lab-grown stones and moissanite. Bindi Irwin has also publicly stated that she chose a moissanite for her engagement ring because “it is beautiful, responsible and perfect for an active lifestyle.”
Sustainable fashion ambassador Emma Watson has appeared multiple times wearing jewelry from independent designers who showcase moissanite as a luxury alternative, while Miley Cyrus and Ariana Grande have worn bespoke rings and pieces created by artisans who pay attention to the gem’s provenance.
Today, choosing a moissanite is not just an alternative:
it is a statement , a declaration of style that combines beauty and conscience , much loved by those who do not follow fashions, but anticipate them .
Because true luxury is knowing what you wear. And why.
Each Alter Luxe creation is made to order, with lead times that reflect the craftsmanship and quality of the materials.
The entire process takes on average 4–5 weeks : up to a week for the CAD preview (when applicable), followed by approximately three to four weeks of custom production.
For some models in 925 Silver , times may be quicker or, in some cases, the jewel may already be ready for shipping .
Once completed, your jewel is shipped via international express courier and arrives in 1–5 working days , in DDP (Delivery Duty Paid) mode: this means that you will not have to pay customs duties upon delivery .
You will receive regular updates at every stage, from the lab to the moment the package reaches your hands.
Yes, but with some conditions that it is good to know in advance.
We accept returns within 14 days of delivery exclusively for 925 Silver jewellery, provided that it has not been worn , is intact , in the original packaging and accompanied by the certificate .
For these returns, there is a 15% restocking fee , and shipping costs are the responsibility of the customer.
Gold or Platinum jewels are made to order and cannot be returned , because they are custom-made, according to the requested specifications (size, metal, finish).
We therefore recommend that you contact us before purchasing to receive support on sizes or technical questions: we want you to be satisfied from the first click.
Choosing the right size is easier than it seems, and we're here to walk you through it every step of the way.
On our website you will find a detailed size guide, with an international conversion table and clear instructions to help you find the correct size, whether you want to measure your finger directly or you have a ring already used on the same finger.
The guide is always accessible in the footer of the site and on the pages of each ring, so you can easily consult it at any time before proceeding with the purchase.
Some of the most effective methods include measuring the inside diameter of a ring you already wear, or printing out our ring sizer and gently wrapping it around your finger. If you’re giving the ring to someone else and want to keep it a surprise, we recommend discreetly using a ring that the person usually wears.
Also consider the type of jewelry and the use it will be put to: a ring to be worn every day, for example, should be comfortable and slightly softer, without being tight.
Since most of our creations — especially those in gold and platinum — are made to order, it is important to carefully choose the size before the ring goes into production, as it is not always possible to change it later.
If you have any doubts or would like a comparison before purchasing, do not hesitate to contact us. We will be happy to guide you in your choice, to ensure that your ring is truly perfect, in every detail.
Absolutely yes. We can create your favorite jewel starting from a simple photo, reinterpreting it with premium materials such as 925 Silver, 10K solid Gold or Platinum , and of course with our high quality moissanite , available in both the classic transparent version and in colored variations .
Whether you want to recreate a ring seen on a celebrity or customize an iconic design, we can transform your inspiration into an ethical, sustainable and bespoke creation , maintaining the same allure but at a fraction of the cost of traditional diamonds.
We will accompany you step by step, from the project to the realization, to offer you a jewel that not only resembles the one of your dreams, but that also reflects your values.
We only use high-quality metals selected for their resistance, beauty over time and safety on the skin : 925 Silver, 10K Gold and Platinum .
All the metals used by Alter Luxe are hypoallergenic , that is, nickel-free and treated to be gentle even on the most sensitive skin. They are chosen not only for their value, but also for their durability over time , because we believe that a jewel should accompany you every day without ever losing its shine.
925 Silver is a noble, elegant and luminous alloy, perfect for a refined and accessible look.
10K gold offers an excellent balance between strength and preciousness, making it ideal for everyday jewelry.
Platinum , finally, is the most resistant and prestigious metal: naturally white, incredibly durable and rare, it is the emblem of eternal luxury.
Every Alter Luxe creation is designed to last — with real, certified, and safe materials.
