Moissanite Engagement Ring: The Ultimate Buying Guide

Bague de fiançailles en moissanite : le guide pour bien choisir

Choosing an engagement ring is a balancing act: you need to guess her taste, get the size right, stick to a budget — and keep it a secret. Here's the step-by-step method.

Step 1: Choose the stone shape

The shape ("cut") of the stone defines the character of the ring:

  • Round (brilliant): The timeless classic. Maximum brilliance, an absolute safe bet.
  • Oval: Elongates the finger, very popular, a brilliance that is "both soft and spectacular".
  • Emerald (rectangular): Art deco elegance, a more subtle and sophisticated "mirror" brilliance.
  • Pear: Romantic and distinctive, points towards the nail to slenderize the hand.
  • Radiant / Cushion: The compromise between the brilliance of the round and the character of the rectangular.

Hint for guessing: look at her current jewelry. Geometric lines → emerald or radiant. Softness and classicism → round or oval.

Step 2: Stone size (equivalent carats)

With moissanite, budget no longer dictates size — it's a matter of proportions and lifestyle. On slender hands, a 1 to 1.5 carat equivalent is already very noticeable. For discreet daily wear, 0.5 to 1 carat is ideal. Our advice: a beautifully set average stone is better than a large, poorly proportioned one.

Step 3: The metal

  • Rhodium-plated silver: Bright white, hypoallergenic, the "white gold" look without the price.
  • 18K yellow gold plated: Classic warmth, enhances golden skin tones.
  • 18K rose gold plated: Romantic and contemporary.

Step 4: Find her ring size (without giving yourself away)

  1. Borrow a ring she wears on her ring finger (left, ideally) and measure its inside diameter.
  2. Compare with a size guide — each WM Paris product page offers one.
  3. When in doubt, choose one size up: discreet resizing is always possible.

Step 5: The budget — and what it allows

Thanks to moissanite (we explain why it costs 10 times less than a diamond), a spectacular engagement ring no longer requires dedicating "three months' salary." At WM Paris, our 925 sterling silver and certified moissanite rings come in a signature box with a certificate of authenticity, with free shipping — for less than €150.
