Forget the outdated “three months’ salary” rule — it’s 2025, not 1985. Your budget should reflect your comfort zone and your priorities. Some clients spend $15,000, others $80,000. What matters most is getting the best possible quality and value within your range.
A good rule of thumb:
Keep 10% aside for resizing, engraving, or insurance. Focus on cut and craftsmanship over size. A well-cut diamond will always look better than a larger, poorly cut one. Lab grown diamonds now offer 30–40% better value, giving you more sparkle for your spend.In 2025, you have more options than ever:
Lab-grown diamonds are chemically identical to mined diamonds and are now mainstream, with transparent sourcing and excellent pricing.
Natural diamonds remain timeless and are still preferred by those who want rarity and tradition.
Coloured gemstones especially sapphires, emeralds, and rubies are increasingly popular for unique, personal designs.

Your setting defines the style and story of your ring. Here’s what’s trending in 2025:
Solitaire – timeless and always elegant.
Hidden halos & bezel settings– modern, minimal, and protective.East–West orientations – contemporary twists for elongated cuts, like our East West Golden Horizon Semi-Bezel Engagement Ring.
Mixed metals – yellow and white gold combinations are making a comeback.
Chunkier bands & vintage inspiration – for bold, sculptural looks, like our Acacia Bezel Asscher Diamond Engagement Ring.
Your metal choice should match your partner’s everyday style — what they wear already is a great clue. Platinum is durable and premium, yellow gold is warm and classic and rose gold is romantic and flattering.
