How the price checker works
We use publicly available market data to calculate what a diamond with your specs typically costs in Hatton Garden. Here is what goes into the calculation.
1
Diamond base price
We start with the typical Hatton Garden price for a diamond at your carat weight, then adjust for shape, cut grade, colour, and clarity. Lab-grown diamonds are priced separately.
2
Setting cost
Different metals and setting styles cost different amounts. Platinum costs more than gold. A halo or three-stone setting uses more material and labour than a solitaire.
3
Range comparison
We combine the diamond and setting costs to give you a typical range, then compare your quote against it. You get a clear verdict — fair, high, or worth investigating further.
Understand what you are paying for
A price is only meaningful if you understand the specs behind it.

Common Questions
How accurate is this price checker?+
The ranges are based on publicly available market data for Hatton Garden jewellers as of 2026. They cover the typical range you would expect to pay — not the cheapest possible price and not the most expensive. Actual prices depend on the specific diamond, the jeweller's overheads, and any bespoke work involved. Use this as a sanity check, not a valuation.
Why might my quote be above or below the range?+
Quotes above the range can reflect premium service, bespoke design work, aftercare packages, or simply a higher-margin business model. Quotes below the range might come from online-first jewellers with lower overheads, or could indicate a diamond graded by a less rigorous lab. The key is to compare like-for-like and always check the certificate.
Does this include the setting or just the diamond?+
The price range includes both the diamond and the setting. You select the metal and setting style, and the tool factors in typical setting costs for Hatton Garden. If your quote includes extras like engraving, resizing, or a presentation box, that could explain a slightly higher figure.
Should I always go with the cheapest quote?+
No. The cheapest quote is not automatically the best. What matters is whether you are paying a fair price for a properly certified diamond from a reputable jeweller who offers aftercare. A GIA or IGI certificate, a clear returns policy, and a jeweller who answers your questions without pressure are worth more than saving a few hundred pounds.
What certificate should I ask for?+
GIA (Gemological Institute of America) and IGI (International Gemological Institute) are the two most trusted independent grading labs. Every diamond you are considering should come with a certificate from one of these labs. If a jeweller offers an in-house certificate or no certificate at all, treat that as a red flag and get a second opinion.
